Summary of the Invention

Problems to be Solved by the Invention

[0004] In Patent Documents 1 and 2, for forming a thin film on the substrate surface, a container filled with a vapor deposition substance or an inorganic material or the like is used. The thin film is formed on the substrate surface by vaporizing the vapor deposition substance from the container or the inorganic material and vapor-depositing the vapor deposition substance on the substrate surface. After the vapor deposition, the container or the inorganic material remains. In order to fill new vapor deposition substance, it is necessary to collect the container or the inorganic material each time. Therefore, there is a demand for a material that can form a thin film in a simpler process.

[0005] An object of the present disclosure is to provide a composite material capable of forming a thin film in a simpler process.

[0007] According to the present disclosure, a composite material capable of forming a thin film in a simpler process can be provided.

Embodiments for Carrying Out the Invention

[0008] The composite material of the present disclosure includes a fluoropolyether group-containing silane compound and a depolymerizable polymer.

[0009] The fluoropolyether group-containing silane compound is a compound containing a fluoropolyether group and a hydrolyzable silane group.

[0010] The depolymerizable polymer is a polymer obtained by reacting an ethylenically unsaturated monomer and having depolymerization characteristics. Here, the ethylenically unsaturated monomer means a monomer having an ethylenically unsaturated bond (i.e., a carbon-carbon double bond) and forming a polymer by a polymerization reaction such as radical polymerization.

[0011] More specifically, the depolymerizable polymer is a polymer containing a structural unit derived from an ethylenically unsaturated monomer and having a chemical structure derived from an ethylenically unsaturated group in the main chain. The depolymerizable polymer has depolymerization characteristics such that the main chain is cleaved by heating and thermally decomposed into ethylenically unsaturated monomers.

[0012] The ethylenically unsaturated monomer is not particularly limited as long as it is a monomer containing an ethylenically unsaturated bond, and examples thereof include monomers having an ethylenically unsaturated group such as a vinyl group, a vinylene group, a vinylidene group, a (meth)acryloyl group, or a (meth)acrylamide group. The hydrogen atom bonded to the carbon atom forming the ethylenically unsaturated bond may be substituted by a halogen atom and / or a substituent.

[0013] As used herein, the term "(meth)acryloyl group" means "acryloyl group" and "methacryloyl group". The same applies to the expression "(meth)acrylate". The term "(meth)acrylamide group" means "acrylamide group" and "methacrylamide group".

[0014] By including the above configuration, the composite material of the present disclosure can form a thin film on the surface of the substrate in a simpler process for the following reasons.

[0015] By applying heat or the like to the composite material of the present disclosure, the depolymerizable polymer is vaporized to deposit the fluoropolyether group-containing silane compound on the substrate surface, thereby forming a layer derived from the fluoropolyether group-containing silane compound on the substrate. The depolymerizable polymer can undergo depolymerization and decomposition due to the applied heat. The decomposition products generated by the decomposition, such as low molecular weight compounds such as ethylenically unsaturated monomers that constituted the depolymerizable polymer, can be gasified by heat and released from the system because of their low binding ability to the substrate. Therefore, after the vapor deposition treatment, the depolymerizable polymer is unlikely to remain as a residue in the system, and the step of recovering the depolymerizable polymer can be omitted.

[0016] In one embodiment, the composite material of the present disclosure may contain the fluoropolyether group-containing silane compound as a liquid compound. For example, the composite material of the present disclosure may contain a solution containing the fluoropolyether group-containing silane compound.

[0017] Since the depolymerizable polymer is unlikely to remain as a residue after the vapor deposition treatment, the composite material of the present disclosure can be suitably used, for example, in a vapor deposition method including a continuous vapor deposition process. In particular, when the composite material of the present disclosure is used in a vapor deposition method including a continuous vapor deposition process, the vapor deposition substance of the liquid compound can be suitably used in the continuous vapor deposition process.

[0018] When a liquid compound is used as a vapor deposition material to be vapor-deposited on a substrate, the vapor deposition material can be filled in a container or carrier made of a porous material such as metal, metal oxide, and / or ceramic and used for vapor deposition. Vapor deposition on the substrate can usually be carried out by heating the container in a chamber under vacuum conditions to vaporize the vapor deposition material. After the vapor deposition process, the container can be recovered. Here, in order to recover the container after the vapor deposition process, it is necessary to return the pressure in the chamber from vacuum to normal pressure. Therefore, when carrying out a continuous vapor deposition process in which a plurality of different vapor deposition materials are vapor-deposited on a substrate, it is necessary to return the pressure in the chamber to vacuum or normal pressure again each time the container is installed and recovered.

[0019] Regarding this point, when a liquid compound is used as a vapor deposition material in a vapor deposition method including a continuous vapor deposition process, it is difficult to carry out efficient vapor deposition from the viewpoint of pressure adjustment during installation and recovery of the above container. For example, in a vapor deposition method including a continuous vapor deposition process, a plurality of chambers communicating with each other are used, and the vacuum state in the chamber can be maintained for several weeks, so it may be difficult to recover the container after the vapor deposition process. When a liquid material is used as a vapor deposition material without using a container, for example, it is conceivable to provide a supply unit for the liquid material, but it may require significant changes to the vapor deposition method and equipment, etc.

[0020] As described above, the composite material of the present disclosure can omit the step of recovering the depolymerizable polymer remaining as a residue after the vapor deposition process. Therefore, when the composite material of the present disclosure is used in a vapor deposition method including a continuous vapor deposition process, a liquid compound can be preferably used as the vapor deposition material.

[0021] Examples of the vapor deposition method including a continuous vapor deposition process include a manufacturing method of an OLED (Organic Light-Emitting Diode).

[0022] The composite material of the present disclosure can further adopt the following embodiments.

[0023] In one embodiment, the fluoropolyether group-containing silane compound may be impregnated in the depolymerizable polymer. "Impregnation" means that the fluoropolyether group-containing silane compound is retained in the structure and / or tissue of the depolymerizable polymer. The fluoropolyether group-containing silane compound may be impregnated in a part of the depolymerizable polymer (for example, the surface or the central part of the depolymerizable polymer), or may be impregnated throughout. By impregnating the depolymerizable polymer with the fluoropolyether group-containing silane compound, more fluoropolyether group-containing silane compound can be contained in the composite material, and the fluoropolyether group-containing silane compound can be more efficiently vapor-deposited on the base material.

[0024] In one embodiment, the depolymerizable polymer has a monovalent organic group or a halogen atom bonded to a carbon atom located at the α-position. By having such a feature, the residue of the depolymerizable polymer after the vapor deposition treatment can be less. The carbon atom located at the α-position means the carbon atom to which the functional group is bonded among the carbon atoms forming the ethylenic unsaturated bond. The type of the functional group is not particularly limited, and may be, for example, one functional group selected from the group consisting of an ester group, a carboxy group, a halogenated carboxy group, a hydroxy group, a ketone group, an amine group, an amide group, an aryl group, and a halogen. From the viewpoint of reducing the residue of the depolymerizable polymer after the vapor deposition treatment, the functional group may preferably be an ester group, an aryl group, or a halogen, more preferably an ester group.

[0025] The "monovalent organic group" means a monovalent group containing carbon. The monovalent organic group is not particularly limited, but may be a hydrocarbon group or a derivative thereof. The derivative of the hydrocarbon group means a group having one or more N, O, S, Si, amide, sulfonyl, siloxane, carbonyl, carbonyloxy, etc. at the terminal or in the molecular chain of the hydrocarbon group.

[0026] In one embodiment, the monovalent organic group is an alkyl group having 1 to 6 carbon atoms. From the viewpoint of reducing the residue of the depolymerizable polymer after the vapor deposition treatment, the alkyl having 1 to 6 carbon atoms is preferably an alkyl group having 1 to 3 carbon atoms, and more preferably a methyl group. The alkyl having 1 to 6 carbon atoms may be linear or branched. The halogen atom includes a fluorine atom, a chlorine atom, a bromine atom, and an iodine atom. From the viewpoint of reducing the residue of the depolymerizable polymer after the vapor deposition treatment, the halogen atom is preferably a fluorine atom.

[0047] The content of the fluoropolyether group-containing silane compound contained in the depolymerizable polymer can be quantified, for example, by the extraction weight by solvent extraction. The solvent used for solvent extraction may be, for example, water, an organic solvent, or a mixture thereof. The organic solvent may be an alcohol-based, ether-based, ketone-based, ester-based, halogen-based, or hydrocarbon-based solvent. Examples of the halogen-based solvent include a chlorine-based solvent or a fluorine-based solvent. The extraction weight may be obtained by removing the solvent after extraction and measuring the weight of the fluoropolyether group-containing silane compound, or may be obtained by analyzing the content of the fluoropolyether group-containing silane compound by instrumental analysis of the solvent after extraction.

[0048] In one embodiment, the depolymerizable polymer may be porous. Porous means a state having a large number of pores on the surface and / or inside. The pores may have a diameter observable by, for example, a scanning electron microscope. When the depolymerizable polymer is porous, it becomes possible to include more of the fluoropolyether group-containing silane compound in the depolymerizable polymer, and the fluoropolyether group-containing silane compound can be efficiently vapor-deposited on the substrate. Note that when the depolymerizable polymer is porous, the composite material of the present disclosure may also be porous.

[0049] In one embodiment, the depolymerizable polymer may be in the form of a tablet or powder.

[0050] When the depolymerizable polymer is in powder form, the average particle size of the depolymerizable polymer may be from 0.1 μm to 100 μm. From the viewpoint of efficiently vaporizing the fluoropolyether group-containing silane compound from the depolymerizable polymer, the average particle size of the depolymerizable polymer may be from 1 μm to 80 μm, preferably from 3 μm to 50 μm. Note that when the particle size of the depolymerizable polymer is within the above range, the composite material of the present disclosure may also have a substantially similar particle size. The average particle size of the depolymerizable polymer in the present disclosure means the primary particle size.

[0051] The method for producing the depolymerizable polymer in powder form is not particularly limited and may be conventional means. For example, a powder-form depolymerizable polymer may be produced by pulverizing a lump-form, granular, or pellet-form depolymerizable polymer with a pulverizer. As another method for producing a powder-form depolymerizable polymer, there may be mentioned a method of obtaining particles by growing atoms or molecules by a chemical reaction and forming aggregates. For example, the powder-form depolymerizable polymer may be produced by emulsion polymerization, suspension polymerization, or the like.

[0052] The average particle diameter of the depolymerizable polymer may be the particle diameter D50 when the cumulative particle volume from the small particle diameter side reaches 50% of the total particle volume in the particle size distribution determined by the laser diffraction / scattering method.

[0053] "Tablet form" means a solid having a certain shape, for example, a tablet-shaped mass. The shape of the tablet-form depolymerizable polymer is not particularly limited and may be a cube, rectangular parallelepiped, sphere, cylinder, prism, cone, pyramid, ellipsoid, circular cylinder, or a combination thereof. By being processed into tablet form, the handleability can be further improved. Note that when the depolymerizable polymer is in tablet form or powder form, the composite material of the present disclosure can be in the same tablet form or powder form as the depolymerizable polymer.

[0054] The tablet-form depolymerizable polymer may be, for example, a product obtained by compressing and molding a powder-form depolymerizable polymer. For example, the tablet-form depolymerizable polymer may be a formed body shaped to have a predetermined shape by tableting and molding at high pressure. In other words, the tablet-form depolymerizable polymer may be an aggregate in which powders are solidified. The tablet-form depolymerizable polymer may be produced by firing a powder-form depolymerizable polymer. Or, it may be dissolved in a solvent or the like and molded into a predetermined shape.

[0055] The size of the tablet-form depolymerizable polymer is, for example, 10 mm 3 ~1000 mm 3It may be.

[0056] From the perspective of improving handleability, as the depolymerizable polymer, in addition to the tablet shape, those obtained by compacting and granulating primary particles may also be used. Regarding the granulation method, the primary particles may be compressed and / or fired. From the perspective of efficiently performing granulation, the primary particles may be granulated in combination with a solvent and / or a binder. The particles after granulation may be spherical or non-spherical. The particle diameter of the particles after granulation may be in the size range of 0.1 to 10 mm, more preferably in the size range of 0.5 to 5 mm. When the particles after granulation are non-spherical, the particle diameter of the particles after granulation may be the long diameter. As the particles after granulation, particles having the same particle size may be used after classification is performed after granulation.

The ceiling temperature of the depolymerizable polymer may be 100 °C or higher, 200 °C or higher, or 300 °C or higher.

[0058] "Ceiling temperature" means the temperature at which the polymerization rate from monomer to polymer and the depolymerization rate from polymer to monomer are in an equilibrium relationship. When the ceiling temperature is exceeded, the depolymerization rate becomes greater than the polymerization rate. When the depolymerizable polymer reaches a temperature exceeding the ceiling temperature, for example, the decomposition of the polymer by depolymerization becomes more dominant than polymerization, and more monomers or oligomers that constituted the polymer are generated, and the monomers or oligomers can be released from the polymer by gasification or the like, so the mass of the depolymerizable polymer can decrease.

[0059] Note that the decrease in the mass of the depolymerizable polymer does not necessarily occur when the ceiling temperature is exceeded. For example, it can occur at a temperature ranging from -20% to +20% of the ceiling temperature, -10% to +10% of the ceiling temperature, or -5% to +5% of the ceiling temperature.

[0060] In one embodiment, the depolymerizable polymer may have a decomposition start temperature of 100°C to 400°C. From the viewpoint of facilitating the control of the depolymerization of the depolymerizable polymer, the depolymerizable polymer may have a decomposition start temperature of 150°C to 350°C, preferably 180°C to 300°C, more preferably 200°C to 260°C. "Decomposition start temperature" means the temperature at which 1 mass% of the depolymerizable polymer decomposes (or decreases) when the depolymerizable polymer is heated from 25°C to 600°C at a heating rate of 10°C / min under a nitrogen atmosphere using thermogravimetric differential thermal measurement.

[0061] In one embodiment, the depolymerizable polymer may have a decomposition end temperature of 300°C to 600°C. From the viewpoint of facilitating the control of the depolymerization of the depolymerizable polymer, the depolymerizable polymer may have a decomposition end temperature of 350°C to 550°C, preferably 400°C to 520°C, more preferably 430°C to 490°C. "Decomposition end temperature" means the temperature at which 99 mass% of the depolymerizable polymer decomposes (or decreases) when the depolymerizable polymer is heated from 25°C to 600°C at a heating rate of 10°C / min under a nitrogen atmosphere using thermogravimetric differential thermal measurement.

[0062] In one embodiment, the glass transition temperature (Tg) of the depolymerizable polymer may be 0 °C or higher and 300 °C or lower, preferably 50 °C or higher and 250 °C or lower, more preferably 70 °C or higher and 200 °C or lower, still more preferably 80 °C or higher and 150 °C or lower, and particularly preferably 85 °C or higher and 125 °C or lower. When the Tg of the depolymerizable polymer is within these ranges, the residue of the depolymerizable polymer after the vapor deposition treatment can be made less. The Tg of the depolymerizable polymer can be obtained by a differential scanning calorimeter (DSC) or the like.

[0063] The average molecular weight of the depolymerizable polymer may be 1,000 or more, 10,000 or more, or 50,000 or more, up to 100,000. The average molecular weight of the depolymerizable polymer may be 500,000 or less, 250,000 or less, or 150,000 or less. The above average molecular weight may be a weight average molecular weight or a number average molecular weight.

[0390] The above fluorinated oil may have an average molecular weight of 500 to 10,000. The molecular weight of the fluorinated oil can be measured using GPC.

[0391] The fluorinated oil may be contained in the composite material of the present disclosure, for example, in an amount of 0 to 50% by mass, preferably 0 to 30% by mass, more preferably 0 to 5% by mass. In one embodiment, the composite material of the present disclosure is substantially free of the fluorinated oil. Substantially free of the fluorinated oil means that it may contain no fluorinated oil at all or may contain a trace amount of the fluorinated oil.

[0392] In one embodiment, the average molecular weight of the fluorinated oil may be made larger than the average molecular weight of the fluoropolyether group-containing silane compound.

[0393] In one embodiment, the average molecular weight of the fluorinated oil may be made smaller than the average molecular weight of the fluoropolyether group-containing silane compound.

[0394] As the silicone oil, for example, a linear or cyclic silicone oil having a siloxane bond of 2,000 or less can be used. The linear silicone oil may be a so-called straight silicone oil or a modified silicone oil. Examples of the straight silicone oil include dimethyl silicone oil, methylphenyl silicone oil, and methylhydrogen silicone oil. Examples of the modified silicone oil include those obtained by modifying a straight silicone oil with alkyl, aralkyl, polyether, higher fatty acid ester, fluoroalkyl, amino, epoxy, carboxyl, alcohol, etc. Examples of the cyclic silicone oil include cyclic dimethylsiloxane oil.

[0395] In the composite material of the present disclosure, such silicone oil may be contained in an amount of, for example, 0 to 300 parts by mass, preferably 50 to 200 parts by mass, based on 100 parts by mass in total of the fluoropolyether group-containing silane compounds of the present disclosure (in the case of two or more kinds, the total thereof, the same applies hereinafter).

[0396] Examples of the compatibilizer include fluorine-substituted alcohols such as 2,2,2-trifluoroethanol, 2,2,3,3,3-pentafluoro-1-propanol, or 2,2,3,3,4,4,5,5-octafluoro-1-pentanol, preferably a fluorine-substituted alcohol having a terminal of CF 2 H, fluorine-substituted aryls such as 1,3-bis(trifluoromethyl)benzene, preferably fluorine-substituted benzenes, etc.

[0397] Examples of the catalyst include acids (such as acetic acid, trifluoroacetic acid, etc.), bases (such as ammonia, triethylamine, diethylamine, etc.), transition metals (such as Ti, Ni, Sn, etc.).

[0398] The catalyst promotes the hydrolysis and dehydration condensation of the fluoropolyether group-containing silane compound of the present disclosure, and promotes the formation of the layer formed on the substrate by the composite material of the present disclosure.

[0399] As other components, in addition to the above, for example, tetraethoxysilane, methyltrimethoxysilane, 3-aminopropyltrimethoxysilane, 3-glycidoxypropyltrimethoxysilane, methyltriacetoxysilane and the like can also be mentioned.

[0400] In addition to the above-described components, the composite material of the present disclosure may contain, as impurities, for example, trace amounts of Pt, Rh, Ru, 1,3-divinyltetramethyldisiloxane, triphenylphosphine, NaCl, KCl, condensates of silanes, and the like.

[0401] In one embodiment, the depolymerizable polymer of the present disclosure may be a carrier material used in combination with a liquid material for vapor deposition. Specifically, the depolymerizable polymer of the present disclosure is a depolymerizable polymer that is a carrier material used in combination with a liquid material for vapor deposition, and in TG-DTA measurement, when the depolymerizable polymer is heated from 25°C to 600°C at a heating rate of 10°C / min in a nitrogen atmosphere, the residue amount of the depolymerizable polymer at 500°C is 5% or less of the initial weight of the depolymerizable polymer, and it may be a depolymerizable polymer for vapor deposition.

[0402] The carrier material means a material capable of containing a vapor deposition substance. For example, the carrier material may be a material capable of holding or supporting a vapor deposition substance. In one embodiment, the carrier material may be composed of a depolymerizable polymer. The liquid material for vapor deposition means a vapor deposition substance that is liquid at room temperature and can be vapor deposited on a substrate. The liquid material for vapor deposition may be composed of a single material or a plurality of materials. For example, the liquid material for vapor deposition may be a solution containing a vapor deposition substance.

[0403] By having the above characteristics, the depolymerizable polymer of the present disclosure can provide a composite material in which the residue of the depolymerizable polymer after vapor deposition treatment is reduced, and a thin film can be formed on the surface of the substrate in a simpler process. Further, it becomes difficult for the depolymerizable polymer to be vapor deposited on the surface of the substrate, and it becomes easier for a layer derived from the liquid material to be formed on the surface of the substrate.

[0404] The TG-DTA measurement of the depolymerizable polymer of the present disclosure can be carried out by heating the depolymerizable polymer from 25°C to 600°C at a heating rate of 10°C / min in a nitrogen atmosphere using thermogravimetric differential thermal measurement. The TG-DTA measurement of the depolymerizable polymer of the present disclosure is described in detail in the examples.

[0405] The residue amount of the above depolymerizable polymer at 500°C may be 3% or less of the initial weight of the depolymerizable polymer, preferably 2% or less, more preferably 1% or less, still more preferably 0.5% or less, and particularly preferably 0.3% or less. The initial weight of the depolymerizable polymer means the weight before heating the depolymerizable polymer.

[0406] In one embodiment, the depolymerizable polymer of the present disclosure is used in combination with a liquid material for vapor deposition. When the liquid material for vapor deposition is vapor-deposited on a substrate, the depolymerizable polymer can also be vapor-deposited on the substrate. In this regard, the amount of the depolymerizable polymer vapor-deposited on the substrate is preferably less than the amount of the liquid material for vapor deposition vapor-deposited on the substrate. Specifically, the amount of the depolymerizable polymer vapor-deposited on the substrate may be, for example, 30% by mass or less of the amount of the liquid material for vapor deposition vapor-deposited on the substrate, preferably 10% by mass or less, more preferably 5% by mass or less, still more preferably 1% by mass or less, and particularly preferably 0.1% by mass or less.

[0407] In one embodiment, the vapor deposition material includes a depolymerizable polymer having the above characteristics and a fluoropolyether group-containing silane compound. By including such characteristics, it becomes difficult for the depolymerizable polymer to be vapor-deposited on the substrate during vapor deposition, and it becomes easier to form a thin film derived from the fluoropolyether group-containing silane compound.

[0408] In one embodiment, the depolymerizable polymer of the present disclosure may be a depolymerizable polymer used in combination with a fluoropolyether group-containing silane compound in the vapor deposition of the fluoropolyether group-containing silane compound. By performing vapor deposition by combining the depolymerizable polymer of the present disclosure and the fluoropolyether group-containing silane compound, it becomes difficult for the depolymerizable polymer to be vapor-deposited on the substrate, and a thin film derived from the fluoropolyether group-containing silane compound is more likely to be formed on the substrate.

[0409] In one embodiment, the composite material of the present disclosure may be a vapor deposition material. The "vapor deposition material" means a material used to vapor-deposit a vapor deposition substance on a substrate or the like. In this regard, it can be understood that the fluoropolyether group-containing silane compound is the "vapor deposition substance" that is vapor-deposited on the substrate, and the depolymerizable polymer is the "carrier material" that supports the vapor deposition substance.

[0410] In one embodiment, the composite material of the present disclosure may contain an additive for adjusting the thermal conductivity of the composite material. Such an additive may be, for example, at least one selected from the group consisting of metals, metal oxides, and ceramic powders. Examples of the metal include silver, copper, gold, nickel, or aluminum. Examples of the metal oxide include alumina, zinc oxide, magnesium oxide, or titanium oxide. Examples of the ceramic powder include silicon nitride, aluminum nitride, silicon carbide, titanium nitride, or titanium carbide.

[0411] In one embodiment, the composite material of the present disclosure may contain an additive for promoting the decomposition of the depolymerizable polymer. Such an additive may be, for example, an organic acid compound or an organic base compound. Examples of the organic acid compound include formic acid, acetic acid, citric acid, maleic acid, lactic acid, oxalic acid, or gluconic acid. Examples of the organic base compound include triethylamine, pyridine, sodium ethoxide, or imidazole.

[0412] In one embodiment, the composite material of the present disclosure may include a crosslinking agent for adjusting the solubility of the depolymerizable polymer. Such a crosslinking agent may be, for example, a polyfunctional compound having radical polymerizability. Such polyfunctional compounds may be, for example, (meth)acrylates having polyfunctional groups, vinyl compounds, allyl compounds, etc. Examples of the functional groups of the polyfunctional compound include an amino group, a hydroxy group, an isocyanate group, a vinyl group, or a carboxy group).

[0413] From the viewpoint of stably storing the composite material of the present disclosure, the composite material of the present disclosure may be stored in a container or the like. For example, during transportation, the composite material may be stored in the above container or the like, and the composite material of the present disclosure may be taken out of the container during use. Such a container preferably has one or more performances selected from the group consisting of light shielding properties, airtightness, gas impermeability, and moisture and water vapor impermeability.

[0414] [Deposition method] The deposition method of the present disclosure is preparing a deposition material by combining a depolymerizable polymer and a fluoropolyether group-containing silane compound, heating the deposition material and depositing the fluoropolyether group-containing silane compound on a substrate.

[0415] By the deposition method of the present disclosure, a layer derived from the fluoropolyether group-containing silane compound is formed on the substrate. The thin film of the fluoropolyether group-containing silane compound can provide excellent water repellency, oil repellency, antifouling properties, etc. For example, the thin film of the above fluoropolyether group-containing silane compound can function as a masking for the substrate during metal patterning of the substrate. Specifically, the thin film of the fluoropolyether group-containing silane compound formed on the substrate repels the deposited metal (that is, has metal repellency), and thus the thin film may have a property that it is difficult for the metal to be deposited thereon.

[0416] The depolymerizable polymer and the fluoropolyether group-containing silane compound used in the vapor deposition method of the present disclosure may be the depolymerizable polymer and the fluoropolyether group-containing silane compound described in the specification of the present application.

[0417] Combining the depolymerizable polymer and the fluoropolyether group-containing silane compound may, for example, involve incorporating the fluoropolyether group-containing silane compound into the depolymerizable polymer. The above combination can be achieved, for example, by bringing the depolymerizable polymer into contact with or mixing it with the fluoropolyether group-containing silane compound.

[0418] In one embodiment, the depolymerizable polymer may be dried before combining it with the fluoropolyether group-containing silane compound. Such drying can reduce the moisture contained in the depolymerizable polymer, making it easier for the fluoropolyether group-containing silane compound to exist more stably after the above combination.

[0419] In one embodiment, the combination of the depolymerizable polymer and the fluoropolyether group-containing silane compound may involve impregnating the depolymerizable polymer with the fluoropolyether group-containing silane compound. The impregnation of the depolymerizable polymer with the fluoropolyether group-containing silane compound may use known methods, for example, vacuum impregnation, pressure impregnation, or vacuum-pressure impregnation, etc.

[0420] In the vapor deposition method of the present disclosure, the vapor deposition of the fluoropolyether group-containing silane compound onto the substrate can be carried out by heating the vapor deposition material. The vapor deposition method may be a conventional vapor deposition method, for example, vacuum vapor deposition. Specific examples of vacuum vapor deposition include resistance heating, electron beam, high-frequency heating using microwaves, etc., ion beam, and similar methods.

[0421] The heating of the vapor deposition material may be to heat the vapor deposition material to 100°C to 600°C. From the perspective of further reducing the residue of the depolymerizable polymer after the vapor deposition treatment, preferably, the vapor deposition material may be heated to 150°C to 550°C, more preferably 200°C to 500°C, still more preferably 250°C to 550°C, and particularly preferably 300°C to 500°C.

[0422] From the perspective of further reducing the residue of the depolymerizable polymer after the vapor deposition treatment, the heating of the vapor deposition material may be at a temperature higher than the ceiling temperature of the depolymerizable polymer, preferably at a temperature 10°C or more higher than the ceiling temperature, more preferably 30°C or more higher, and still more preferably 50°C or more higher.

[0423] From the perspective of making it easier to vaporize the fluoropolyether group-containing silane compound from the vapor deposition material, the vapor deposition may be carried out under reduced pressure. For example, the vapor deposition may be carried out under a pressure of 10 -1 Pa to 10 -5 Pa, preferably 10 -1 Pa to 10 -4 Pa, more preferably 10 -2 Pa to 10 -4 Pa.

[0424] The substrates that can be used in the vapor deposition method of the present disclosure can be composed of, for example, glass, resin (natural or synthetic resin, such as common plastic materials, and may be in the form of plates, films, or other forms), metal (a single metal such as aluminum, copper, iron, etc. or a composite such as an alloy), ceramics, semiconductors (such as silicon, germanium, etc.), fibers (such as woven fabrics, non-woven fabrics, etc.), fur, leather, wood, ceramics, stone, etc., building members, etc., any suitable material.

[0425] As the glass, sapphire glass, soda-lime glass, alkali aluminosilicate glass, borosilicate glass, non-alkali glass, crystal glass, and fused silica glass are preferable, and chemically strengthened soda-lime glass, chemically strengthened alkali aluminosilicate glass, and chemically bonded borosilicate glass are particularly preferable. As the resin, acrylic resin and polycarbonate are preferable.

[0426] Such a substrate may be made of a material that originally has hydroxyl groups at least on its surface portion. Examples of such materials include glass, metals (especially base metals) on which a natural oxide film or a thermal oxide film is formed on the surface, ceramics, semiconductors, etc. Alternatively, when it is not sufficient to have hydroxyl groups like resins, etc., or when there are no hydroxyl groups originally, by subjecting the substrate to some pretreatment, hydroxyl groups can be introduced or increased on the surface of the substrate. Examples of such pretreatment include plasma treatment (e.g., corona discharge) and ion beam irradiation. Plasma treatment can be suitably used not only to introduce or increase hydroxyl groups on the substrate surface but also to clean the substrate surface (remove foreign substances, etc.). Another example of such pretreatment is a method in which an interfacial adsorbent having a carbon-carbon unsaturated bond group is formed in the form of a monomolecular film on the substrate surface in advance by the LB method (Langmuir-Blodgett method) or chemical adsorption method, etc., and then the unsaturated bond is cleaved in an atmosphere containing oxygen, nitrogen, etc.

[0427] Or, such a substrate may be made of a material that contains at least on its surface portion another reactive group, for example, a silicone compound having one or more Si-H groups or an alkoxysilane.

[0428] In a preferred embodiment, the substrate is glass.

[0429] The shape of the above substrate is not particularly limited and can be appropriately determined according to the use and specific specifications of the article to be manufactured.

[0430] The thickness of the above-mentioned substrate may be, for example, in the range of 0.1 mm to 30 mm.

[0431] As the above-mentioned substrate, if necessary, a substrate that has been partially protected in advance by masking or the like may be used.
