[0010] The object of the present invention is to provide an electrically conductive multi-component system and a method for producing an electrically conductive multi-component system, in particular to enable controlled metering of the components of the multi-component system and their arrangement, so as to increase the reaction efficiency of the multi-component system on the one hand and to achieve a precise and accurately defined electrical conductivity on the other hand.
[0011] According to the invention, the object is achieved by a multi-component system having the features of claim 1. A conductive multi-component system having at least one first substance and at least one substrate is provided, wherein a) the first substance is present in one or more substance parts, b) at least one first substance part is formed with at least one first functional group and is provided with a first linker (or linking group) and / or wherein the substrate is formed with at least one second functional group and is provided with a second linker, c) the first functional group reacts with the second functional group and / or the substrate via a predetermined interaction and connects them to one another and / or wherein the second functional group reacts with the first functional group and / or the first substance via a predetermined interaction and connects them to one another, d) the substance parts of the first substance are present as particles or in particle form and are at least partially conductive.
[0012] The invention is based on the basic idea that at least one first substance and at least one substrate are arranged in a defined manner relative to one another by means of a defined spatial arrangement by means of a linker and a connection by means of functional groups. Thus, the first substance and the substrate can now be arranged in a defined ratio (relationship) and at a defined distance. Conductivity can be achieved by corresponding activation, in particular in the region in which the first substance is bonded to the substrate. Even in very small structures, conductivity can be produced in a very specific and well-defined manner. In particular, it is conceivable that conductive connections in the micrometer range or nanometer range or smaller are produced here by means of a multicomponent system, which are usually produced by bonding or soldering or gluing or the like. The at least one particle can in particular be a microparticle or a nanoparticle.
[0013] In particular, it can be provided that the conductivity of the material part is electrical conductivity and / or thermal conductivity and / or signal conductivity.
[0014] It is conceivable that the particles can self-assemble or self-align. Here, the particles can be arranged independently on the substrate in a predeterminable or predetermined direction, for example, a conductor track.
[0015] Self-assembly can be achieved, for example, by thiol groups (SAM surfaces, see also below) and / or Janus (nano) particles, and / or plate-like particles, and / or by magnetism (particle and surface magnetism) and / or by electrostatic interactions. Such interactions can be achieved, for example, by positively charged surfaces, negatively charged surfaces and / or by weak interactions and / or by chemical reactions, such as linking chemistry (e.g. Thiol-Ene-Click-Chemie), Michael reactions, etc.
[0016] Furthermore, it can be provided that the distance between the functional group and the substance moiety and the substrate is determined by the corresponding linker.
[0017] The substrate can be a circuit board or printed circuit board or a conductor track, for example in the field of semiconductor technology (wafer (for example silicon wafer or silicon wafer) or chip). In particular in the field of microelectronics, i.e. when connecting conductor tracks on circuit boards or chips or 3D integrated bodies etc., an electrically conductive connection at the correct position is of great advantage, which is also stable, has a higher conductivity, has fewer short circuits and allows miniaturization. The electrically conductive connection can be produced on the substrate by means of a multi-component system as follows: first the multi-component system is positioned, in which case position correction is also possible; then the multi-component system is activated (for example as described below) and the electrically conductive connection is produced.
[0018] If (individual (or single)) particles are used, it is possible, for example, to produce an electrically conductive connection between two conductor tracks by the particles contacting the two conductor tracks and then being fixed there accordingly by activation.
[0019] In the case where a plurality (or a plurality) of particles are present, the particles are in contact with one another and form a “constant path” between two conductor tracks. This also produces a correspondingly conductive connection.
[0020] Activation releases the particles. The particles then align themselves at the desired locations (so-called self-assembly) via, for example, terminal sulfhydryl groups or conductive polymers or via Janus (nano) particles. This process can also be supported, for example, by magnetic and / or electric fields.
[0021] It can also be provided that the substrate is a second substance.
[0022] In particular, it can be provided that the functional groups of the substance part of the first substance and the functional groups of the substrate bind specifically to one another.
[0023] In particular, it can also be provided that the functional groups of the substance moieties bind selectively to metal surfaces, for example SAM surfaces (self-organized monolayers).
[0024] The nanoparticles may consist at least partially of silver, gold and / or copper and / or composites and / or other metals or alloys thereof and / or other materials.
[0025] Furthermore, it can be provided that the substrate is a surface or has a surface. The surface can be, for example, a wafer, a (micro)chip, a flexible electronic device or a printed circuit board or the like. Furthermore, it is conceivable that the surface is a conductive substrate. The substrate can also be a substrate with printed conductors. The printed conductors can, for example, be deposited, printed or etched. The printed conductors can also be applied to the substrate using thin-film technology or some other technology.
[0026] In particular, it can be provided that the size of the nanoparticles is smaller than the distance between the conductor tracks.
[0027] It is also conceivable that the first connector is longer than the second connector, or vice versa. This leads to the advantage that, for example, the distance between the first substances after corresponding bonding is greater or smaller than the distance between the first substance and the substrate.
[0028] Alternatively, both connectors are of the same length.
[0029] The linker can be any form of connection between a moiety and a functional group.
[0030] The linker may also be any type of direct connection between the substance moiety and / or the capsule and / or the substrate and the functional group.
[0031] Possible linkers include biopolymers, proteins, silk, polysaccharides, cellulose, starch, chitin (chitin), nucleic acids, synthetic polymers, homopolymers, DNA, halogens, polyethylene, polypropylene, polyvinyl chloride, polylactams, natural rubber, polyisoprene, copolymers, random copolymers, gradient copolymers, alternating copolymers, block copolymers, graft copolymers, acrylonitrile-butadiene-styrene (ABS), styrene-acrylonitrile (SAN), butyl rubber, polymer blends, polymer alloys, inorganic polymers, polysiloxanes, polyphosphazenes, polysilazanes, ceramics, basalts, isotactic polymers, syndiotactic polymers, atactic polymers, linear polymers, cross-linked polymers, elastomers, thermoplastic elastomers, thermosetting polymers, semicrystalline linkers, thermoplastics, cis-trans polymers, conductive polymers, supramolecular polymers.
[0032] It is also conceivable that the functional group is homogeneous or heterogeneous. For example, it is conceivable that a substance and the relevant functional group are heterogeneous, that is, different functional groups can be used. This is desirable, for example, when it is desired to achieve the following: for example, in the manufacturing process, some connectors are first provided with protective groups and will be used for some combinations (or binding), such as the first substance and the first substance or the first substance and the substrate (or the substrate and the substrate). It is also conceivable that the first functional group can connect two material parts, and the different second functional groups can connect the first substance to the substrate. It is also conceivable that the first functional group can combine material parts, and the different second functional groups can change the characteristics of the capsule, such as biocompatibility, solubility, aggregation or similar characteristics. It is also conceivable that heterogeneous functional groups make it possible to design three-component or multi-component systems.
[0033] Instead of a protective group, it is also possible to provide alternatively for two bonds to be present, wherein the first bond binds the capsules to one another and the second bond binds the capsule or the substance part or substance to a substrate, a surface or a fiber or the like.
[0034] However, it is also conceivable that all functional groups are homogeneous, ie identically formed. In the case of a heterogeneous design, it is also conceivable to combine this with other properties or differences in the linker design (eg length, angle, linker type, etc.).
[0035] It is also conceivable that the substance of the first substance is arranged in a capsule, in particular in a nanocapsule and / or a microcapsule. Encapsulation can easily provide a first substance of a defined mass or a defined volume for a conductive multi-component system. For a multi-capsule system or, for example, a two-component capsule system (2K-capsule system), the capsule contents can be combined with each other in a defined amount and / or a defined ratio or amount and distance in a separate volume until the capsule is activated and the contents of the capsule can react with each other or be forced to react with each other or mix when the capsules have the same contents. One or more substance parts of the substance are arranged or packaged in each capsule. It is also conceivable that the capsule contains a plurality of substance parts. The capsule arrangement with the first substance (or the second or third substance) can also be referred to as a capsule complex and has a function roughly similar to a (micro) reaction flask, in which the reagents are mixed with each other after activation at a defined time point and the reaction between the substances is started. A large number of these capsule complexes makes the effect cumulative, and a greater effect occurs or the mixing and reaction of the substances is improved. Another advantage comes from the better mixing of the individual substances or reaction components with each other, so that - compared with previous systems - higher conversion rates can be achieved, while reducing material consumption.
[0036] Possible capsule types include, for example, double capsules, multi-core capsules, capsules with cationic or anionic properties, capsules with different shell materials, Janus particles, lamellar particles, porous capsules, capsules with multiple shells, capsules with metal nanoparticles, matrix capsules and / or hollow capsules, capsules with multiple layers of shell material (so-called multilayer microcapsules) and / or empty porous capsules (e.g. for encapsulating odors).
[0037] Furthermore, it can be provided that the capsules for the first substance have the same size. This results in an adjustment of the volume ratio of the first substance to the substrate (or vice versa) and / or an adjustment of the activation behavior (if at least part of the multicomponent system is activatable).
[0038] It is also conceivable that at least part of the multi-component system is activatable and that the activation of the multi-component system is carried out by at least one change in pressure, pH value, UV radiation, penetration, temperature, light intensity, moisture, etc. This has the advantage that the time point of activation can be precisely controlled. It is conceivable to provide one or more activation mechanisms. In the case of providing a plurality of activation mechanisms, redundant activation options are created. Thus, for example, it is ensured that activation is always possible.
[0039] Furthermore, it can be provided that the nanoparticles consist of a metallic material and have a surface coating, in particular a metallic surface coating and / or a surface functionalization. In particular, the nanoparticles can have electrical conductivity and / or magnetic properties.
[0040] The metallic surface coating may comprise any metal and / or any metal alloy, in particular gold, silver, copper and / or bronze.
[0041] In particular, magnetic, electrically conductive nanoparticles (coated with an electrically conductive metal) can thus be obtained.
[0042] The metal surface of the nanoparticles can be achieved by functionalization with terminal reactive groups, in particular with polymers having at least one thiol group, for example 11-mercaptoundecanoic acid or the like, or more thiol groups, for example dithiols, in particular 1,2-ethanedithiol, 1,3-propanedithiol, 1,4-butanedithiol, 1,5-pentanedithiol, benzene-1,4-dithiol, 2,2'-ethylenedioxydiethanethiol, 1,6-hexanedithiol, tetrakis(ethylene glycol)dithiol, 1,8-octanedithiol, 1,9-nonanedithiol, 1,11-undecanedithiol, hexa(ethylene glycol)dithiol, 1,16-hexadecanedithiol or the like.
[0043] It is also conceivable that the nanoparticles are, for example, round, oval, angular, rod-shaped, rhombus-shaped, spherical, egg-shaped, cuboid, cylindrical, conical or star-shaped or take any other common or unusual shape.
[0044] Furthermore, the surface coating and / or the surface functionalization can be formed at least partially, in particular completely, by terminal functional groups and / or linkers which selectively bind to the metal surface and / or the SAM surface and / or the stabilizer.
[0045] Generally, stabilization of the nanoparticles can be performed by steric stabilization, electrostatic and / or electrochemical stabilization and / or other stabilization methods.
[0046] In particular, it can be provided that the stabilizer is polyethylene glycol (PEG) and / or polyvinyl alcohol (PVA) and / or citrate, and / or an organic ligand or the like.
[0047] Furthermore, the surface coating may be a conductive surface coating, such as a conductive polymer.
[0048] It is also conceivable that the nanoparticles are stabilized by a matrix, in particular an environmental matrix.
[0049] Furthermore, it can be provided that the matrix consists of at least one polymer, an adhesive or another electrically non-conductive material.
[0050] It is also conceivable that the nanoparticles each have at least one shell and at least one core. For example, so-called core-shell or core-shell-shell nanoparticles are conceivable.
[0051] Furthermore, it can be provided that the core contains an environmental matrix.
[0052] It can also be provided that the nanoparticles are accommodated in particles, wherein the particles have at least one core and at least one shell, wherein the core or at least one core contains at least one nanoparticle.
[0053] It is conceivable that the core consists of at least one magnetic metal, in particular iron, nickel, cobalt, gadolinium, terbium, dysprosium, holmium and / or erbium.
[0054] It is conceivable that the nanoparticles are magnetic nanoparticles and / or are not provided with functional groups.
[0055] It is contemplated that the surface coating is formed with terminal functional groups and / or linkers that selectively bind to the metal surface, and / or form a SAM surface and / or stabilizer and in a polar solvent.
[0056] Furthermore, it can be provided that at least some of the nanoparticles are arranged in a first capsule and that a second substance portion is provided which is also arranged in at least one capsule, wherein the capsules are in each case activatable.
[0057] The nanoparticles may have substantially the same size and / or the second substance portion may have substantially the same size. Size may particularly refer to spatial extent, but may also refer to mass or occupied volume. It is conceivable that the nanoparticles and the second substance portion each have the same size or amount.
[0058] However, it is also conceivable in particular that the nanoparticles and the second substance portion have different sizes.
[0059] For example, it is conceivable that the nanoparticles are in a first capsule and the adhesive, in particular an epoxy resin or a PU adhesive or an acrylate adhesive, is in a second capsule. In particular, a double microcapsule can be provided. The nanoparticles in the first capsule and the epoxy resin in the second capsule can be released by activation. This allows the formation of electrically conductive bonding points. The activation can be carried out as described above. In particular, this allows a precisely controlled (in time and space) conductivity of the substrate to be achieved.
[0060] Any type of one-component adhesive and / or resin in the sense of an adhesive is conceivable.
[0061] Any form of multi-component adhesives, in particular resins and curing agents, can also be envisioned. In the case of multi-component adhesives, the components can be present in different capsules and / or capsule groups and / or capsule types. Two-component adhesives are also conceivable (e.g., capsules for granules, capsules for a first adhesive component and a second capsule for a second adhesive component).
[0062] It is envisaged that the capsules (or substance portions) may be activated simultaneously and emptied simultaneously.
[0063] It is conceivable that the capsules may be activated one by one and emptied one by one.
[0064] The choice of size also determines the corresponding (local) volume and / or the corresponding local concentration of the corresponding substance.
[0065] The multicomponent system can have a network structure with gaps, wherein the network structure is formed by material parts of the first substance, wherein the surrounding medium and, if appropriate, at least in sections, at least one material part of the second substance are arranged in the gaps.
[0066] The capsules are formed or functionalized with a linker and a functional group. The linker should crosslink the capsules to one another. It can be provided that the functional groups are also provided with protective groups. The distance between the capsules can be determined by the length of the linker. The length of the linker is selected so that the radius of the contents of the capsules emptied of liquid slightly overlaps the volume of the adjacent capsules to ensure crosslinking. In the case of a more viscous ambient medium, the length of the linker is selected to be smaller than in the case of a less viscous medium, such as a paste or a liquid.
[0067] Generally, the in-line (intra-linking, or intra-group cross-linking) of capsules is possible. In this case, the capsules of a capsule group are cross-linked with each other.
[0068] Typically, capsules with the same contents can be cross-linked by interlinking.
[0069] Generally, the interlinking (intervernetzung, or called intergroup crosslinking) of capsules is possible as an alternative or in addition. Here, capsules from at least two different capsule groups are crosslinked with each other.
[0070] Typically, capsules with different contents can be cross-linked via intermolecular cross-linking.
[0071] A selected release profile can also be achieved by capsules of a multi-component capsule system, for example a two-component capsule system. For example, a gradual and / or delayed release of various substances can be envisaged.
[0072] It is also conceivable that in a batch process, two capsule populations of a two-component capsule system on a carrier material are interconnected with each other with identical contents but different activation mechanisms. This can achieve a more sustained release compared to a one-component capsule system.
[0073] The capsules can generally be manufactured by physical methods, chemical methods, physicochemical methods and / or the like.
[0074] Capsules can generally be made by solvent evaporation, thermal gelation, gel formation, interfacial polycondensation, polymerization, spray drying, fluidized bed, droplet freezing, extrusion, supercritical fluid, coacervation, air suspension, pan coating (pan coating), coextrusion, solvent extraction, molecular incorporation, spray crystallization, phase separation, emulsion, in situ polymerization, insolubility, interfacial deposition, emulsification with nanomolecular sieves, ionotropic gelation, coacervate phase separation, matrix polymerization, interfacial crosslinking, coagulation, centrifugal extrusion and / or one or more other methods.
[0075] The shell of the capsule may generally comprise at least one polymer, wax resin, protein, polysaccharide, gum arabic, maltodextrin, inulin, metal, ceramic, acrylate, microgel, phase change material, and / or one or more other substances.
[0076] The shell of the capsule may generally not be porous or not completely porous. The shell of the capsule may generally be almost completely impermeable or completely impermeable.
[0077] The core of the capsule may generally be solid, liquid and / or gas.
[0078] In general, the capsules can be formed from linear polymers, multivalent polymers, star-shaped polyethylene glycols, self-assembled monolayers (SAMs), carbon nanotubes, ring-shaped polymers, DNA, dendrimers, ladder polymers and / or similar substances.
[0079] As SAM surface, disulfide, phosphoric acid, silane, thiol and polyelectrolyte can be used. In particular, acetylcysteine, dimercaptosuccinic acid, dimercaptopropanesulfonic acid, ethanethiol (ethanethiol (Ethylmercaptan)), dithiothreitol (DTT), dithioerythritol (DTE), captopril, coenzyme A, cysteine, penicillamine, 1-propanethiol, 2-propanethiol, glutathione, homocysteine, mesna, mercapto undecanoic acid, mercapto undecane alcohol, methyl mercaptan (methyl mercaptan (Methylmercaptan)) and / or thiophenol can be used.
[0080] Furthermore, the invention relates to a method for producing a conductive multi-component system having at least one first substance and at least one substrate, wherein the first substance is present in one or more substance parts, the method comprising the following steps:
[0081] - at least one or more first material parts are formed with at least one first functional group and provided with a first linker, and / or the substrate is formed with at least one second functional group and provided with a second linker,
[0082] The first functional group reacts with the second functional group and / or the substrate via a predetermined interaction to establish a conductive connection, and / or wherein the second functional group reacts with the first functional group and / or the first substance via a predetermined interaction to establish a conductive connection.
[0083] In particular, it is conceivable that the method is carried out in such a way that an electrically conductive multi-component system is provided, which has at least one first substance and at least one second material, wherein the first substance is present in a plurality of substance parts, the method comprising the steps of:
[0084] - a first material portion is formed with at least one first functional group and is provided with a first linker,
[0085] - the second material is formed with at least one second functional group and is provided with a second linker,
[0086] - the first functional group reacts with the second functional group via a predetermined interaction, thereby connecting them to each other, and
[0087] The distance between the functional group and the corresponding substance part is determined by the corresponding linker.
[0088] In particular, it can be provided that the first substance part is formed with at least one third functional group and is provided with a third linker, wherein the third functional groups each have at least one protecting group, so that only the correspondingly functionalized substance part of the first substance is bound to the substance part of the first substance, and wherein the method further comprises at least the following steps: the protecting group is initially present and is only removed when the first substance parts are to be connected to each other via the third functional group. This prevents the substance part of the first substance (i.e. the first substance part), in particular the capsule, from already and initially being connected to other substance parts of the first substance. The protecting group can be removed after being provided in the form of a gaseous, low-viscosity, liquid, high-viscosity or solid phase, whereby inlining occurs.
[0089] Furthermore, it can be provided that the multi-component system is a multi-component system according to one of claims 1 to 12 .

[0362] Fig.21 A further exemplary embodiment of a multicomponent system 1210 according to the invention is shown, namely a functionalized system with (nano)particles having double microcapsules.
[0363] In this case, capsule K10 is filled with a binder and capsule K20 is filled with (electrically) conductive particles (eg one or more rod-shaped nanoparticles).
[0364] In this embodiment, the binder is in a first microcapsule and the at least one (nano)particle and / or carbon nanotube is in a second microcapsule.
[0365] The binder is encapsulated in the microcapsule K10. At least one (nano)particle made of (electrically) conductive material is located in the microcapsule K20.
[0366] Here, the surface of the (nano)particles may be functionalized with functional groups R, for example terminal thiol groups or other functional groups R. The shell of the microcapsule K10 may consist of the same material and the same thickness as the shell of the microcapsule K20. Furthermore, the microcapsule K10 may have the same dimensions as the microcapsule K20. However, the parameters may also differ from one another in at least one or more points.
[0367] The mechanism can be a parallel opening mechanism:
[0368] The microcapsules are applied to the metal area / metal surface. The second metal surface is then positioned parallel to the first metal surface. Due to the defined activation mechanism, the two microcapsules open at the same time and release the contents. Here, the released nanoparticles functionalized with terminal functional groups (e.g. thiol groups) are combined with the two surfaces of the metal surfaces arranged in parallel. The (nano) particles form a network with each other. This can be achieved by aggregation and / or by combining functional groups such as thiol groups with each other (interlinking). After the activation of the microcapsules K10 filled with adhesive, the microcapsules K10 are emptied and the (nano) particle connections of the (electrically) conductive connections are stabilized. In addition, the adhesive bonds the upper and lower surfaces together.
[0369] A sequential opening mechanism is also conceivable:
[0370] Microcapsules are applied to the metal area. Microcapsules K10 have a different opening mechanism than microcapsules K20. The second metal surface is then positioned parallel to the first metal surface. By a defined activation mechanism, such as temperature, the microcapsules with (nano) particles are first opened and their contents are released. Here, the released nanoparticles functionalized with terminal functional groups R2, such as thiol groups, are bound to the two surfaces of the parallel metal surfaces. The (nano) particles form a network with each other. This can be achieved by aggregation and / or by bonding functional groups, such as thiol groups, to each other (interlinking and inlinking). By the second opening mechanism, this is preferably achieved by microcapsules K10 having a different shell material from microcapsules K20 and / or different sizes and / or different thicknesses of the shell material of microcapsules K10. The following second activation mechanisms are conceivable, such as ultrasound, pH changes, induction, pressure, etc. In addition, sequential activation can be achieved by changing the first activation mechanism, such as by increasing the temperature. After activation of the microcapsules 1 filled with adhesive, the microcapsules 1 are emptied and the (nano) particle connections of the (electrically) conductive (nano) particles are stabilized. Furthermore, an adhesive bonds the upper and lower surfaces together.

[0372] Here, the binder is encapsulated in microcapsules K10. (Nano)particles are in microcapsules K20, which are made of (electrically) conductive material. Here, the (electrically) conductive surface of the conductor track is functionalized with terminal thiol groups. The (nano)particles are not functionalized.
[0373] The mechanism can be a parallel opening mechanism:
[0374] The microcapsules are applied to the metal area. Then, the second metal surface is positioned parallel to the first metal surface. Through a defined activation mechanism, the two microcapsules open simultaneously and release the contents. Here, the released nanoparticles bind to the two surfaces of the parallel metal surfaces functionalized with terminal thiol groups. The (nano)particles form a network with each other. This is achieved by mutual aggregation.
[0375] A sequential opening mechanism is also conceivable:
[0376] The connection mechanism here is Fig.21 The mechanism is the same as described in the exemplary embodiment of , except that the surface is functionalized instead of the (nano)particles.
[0377] Fig.23A further exemplary embodiment of a multi-component system 1410 according to the invention is shown, namely a functionalized variant with (nano)particles and (electrically) conductive surfaces.
[0378] The binder is encapsulated in microcapsules K10. The (nano)particles made of (electrically) conductive material are in microcapsules K20. Here, the surface of the (nano)particles is functionalized with terminal thiol groups, as is the (electrically) conductive surface of the conductor track (i.e. substrate B).
[0379] Here, both parallel and sequential opening mechanisms are conceivable (see above in conjunction with Fig.21 and 22 Description of exemplary embodiments of the present invention).
[0380] Fig.24 A further exemplary embodiment of a multi-component system 1510 according to the invention is shown, namely a variant with homogeneous functionalization of the (nano)particles and functionalization of the (electrically) conductive surface with reactive functional groups (excluding thiols).
[0381] In this variant, microcapsules K10 are filled with a binder. Microcapsules K20 are filled with functionalized (nano)particles. The (electro)conductive surface is functionalized by complementarity with the functional groups of the (nano)particles.
[0382] The opening mechanisms may occur in parallel or sequentially (see above in conjunction with Fig.21 and 22 Description of exemplary embodiments of the present invention).

[0384] In this exemplary embodiment, both surfaces of the substrate B (nano)particles and the (electrically)conductive surface are "charged" (in other words). Here, the surface of the (nano)particles is negatively charged. The surface of the (electrically)conductive surface (of the substrate B) has a positive charge. In another embodiment variant, the surfaces can also be oppositely charged, i.e. the (nano)particles are positively charged and the (electrically)conductive surface or substrate B is negatively charged.
[0385] Fig.26 A further exemplary embodiment of a multicomponent system 1710 according to the invention is shown, namely a variant with heterogeneous functionalization of the (nano)particles (substance S1 ) for inter- and intra-connection and functionalization of the (electrically) conductive surface (substrate B).
[0386] In this exemplary embodiment, the (nano)particles are functionalized with two different functional groups. Here, one functional group may be a terminal thiol R4 and the other functional group may be a carboxyl R2. The (electrically)conductive surface is functionalized with a functional group complementary to the (nano)particles. In this example, it is a terminal primary amine R1. The (nano)particles are cross-linked to each other (by interlinking and / or interlinking) via the thiol groups.
[0387] Fig. 27 A further exemplary embodiment of a multicomponent system 1810 according to the invention is shown, namely a variant with functionalization of the microcapsules (substance S1).
[0388] Double microcapsules are prepared as described above. Another functional group, which is not responsible for the mutual binding of the microcapsules, is bound to the (electrically) conductive surface (substrate B). For this purpose, in particular terminal thiols should be used which only selectively bind to metal regions. In this way, the microcapsules can only be placed at the desired locations (for example) on the metal surface, which means that there is no conductivity in the x direction.
[0389] Fig.28 A further exemplary embodiment of a multi-component system 1910 according to the invention is shown, namely a functionalized variant with an (electrically) conductive surface (substrate B).
[0390] In this exemplary embodiment, the (electrically) conductive surface is functionalized with a terminal thiol group R1. At least one nano- and / or microcapsule has metal (nano) particles on its surface. By applying the microcapsules to the surface, the microcapsules with metal (nano) particles selectively bind only to the surface with the terminal thiol group.
[0391] Instead of metal (nano)particles, the microcapsules can also be completely and / or partially coated (or sheathed) with a metal surface.

[0393] Here, the surface of the microcapsules is provided with metal nanoparticles. By adding a compound R3 with a terminal polymer, for example a thiol compound, the (nano)- and / or microcapsules can be functionalized. The second functional group of the polymer can be provided with a further functional group R5. In this way, the thiol group R3 is bonded to the metal particles of the (nano)- and / or microcapsules. The second functional group remains active and is available for further reactions. Thus, the microcapsules have a defined number of defined functional groups.
[0394] Using dithiols, microcapsules can be functionalized and bound to (electrically) conductive surfaces.
[0395] Fig.30 and 31 A further exemplary embodiment of a multicomponent system 2110 or 2210 according to the invention is shown in each case, namely an alternative functionalization with thiol groups.
[0396] In order to bond the microcapsules K10 , K20 to the (electrically) conductive surface (substrate B), the (nano)- and / or microcapsules K10 , K20 are provided with functional groups R3 and the (electrically) conductive surface B is coated with complementary functional groups R1 .
[0397] Here, only one of the double microcapsules can be provided with functional groups (cf. Fig.30 ) or the two microcapsules in the double microcapsules may be provided with functional groups (see Fig.31 ).
[0398] Figure 32 to Figure 34 Each shows a method according to the present invention having multiple microcapsules (each suitable for attachment to a substrate ( Figures 32 to 34 Another exemplary embodiment of multi-component systems 2310 , 2410 , 2510 , and 2610 )) is not shown.
[0399] Figure 32 to Figure 34 The exemplary embodiments shown can be produced according to the production steps described above and below and can accordingly have corresponding features of other systems.
[0400] Here, the adhesive (glue) can be a one-component or two-component adhesive, wherein the adhesive can be in the same and / or separate material parts. It is also conceivable that if it is a multi-component adhesive, then even a plurality of components can be provided accordingly.
[0401] Fig.32 A multi-component system 2310 is shown, which (viewed from left to right) has a binder 1 in a substance portion K10 of a first capsule (far left), a single nanoparticle in a second capsule K20, and another capsule K10 with binder 1. Embodiments with multiple nanoparticles in one capsule are also conceivable.

Binder 1 and Binder 2 may be components of a single, dual, or multi-component adhesive.
[0405] In principle, through the above exemplary embodiments, (electrical) conductivity can be achieved in a specific, specified or specifyable direction as follows: wherein the conductivity is not limited to electrical conductivity, but can involve the transmission of electrical conductivity, heat, data, etc.:
[0406] Use is made of (nano)particles or magnetic particles functionalized with terminal thiol groups or substrates and / or particles provided with functional groups. Electrostatic interactions can also be used.
[0407] The terminal functional groups may be provided with protecting groups.
[0408] The nanoparticles and binder can be encapsulated, for example, in microcapsules.
[0409] Then proceed as follows:
[0410] 1. As described in (our first patent), microcapsules wrapped with (nanoparticles) are aggregated together in an ambient medium.
[0411] 2. The microcapsules open and release particles through an activation mechanism (e.g. temperature)
[0412] 3. Arrange the particles in the desired direction through chemical reactions, self-assembly, magnetism or other mechanisms.
[0413] 4. Fixing the particles by passing them through an ambient medium, for example, also by heating.
[0414] The opening of the microcapsules, the alignment of the particles and the solidification of the surrounding medium can take place in parallel or sequentially.
[0415] In another exemplary embodiment, for example, the structure can be made into three layers, namely a surface (substrate), then a first layer (e.g., an environmental medium, such as an adhesive, a SAM coating, etc.), then a second layer with microcapsules in which the nanoparticles are encapsulated, and then a third layer (an environmental medium, such as an adhesive).
[0416] Here, the surface or substrate is first coated.
[0417] This is followed by coating with functionalized capsules with nanoparticles, which can be opened by a defined activation mechanism.
[0418] Here, the terminal functional groups may be blocked with protecting groups.
[0419] The particles are arranged along the X direction through chemical reactions such as self-assembly, electrostatic interaction, magnetism, etc.
[0420] In all of the above-described exemplary embodiments, it is in principle also possible to use a plurality of nanoparticles in one capsule.
[0421] For example, a single nanoparticle can be isolated and placed in a capsule using Nanoporetech's technology (see Venkatesan, Bala Murali and Rhashid Bashir, Nanopore Sensors for nucleic acid analysis, Nature Nanotechnology 6.10 (2011): 615). This method allows only a single DNA strand to pass through a single channel and can also be used to isolate nanoparticles.
