These polymerization initiators may be used alone or in combination of two or more kinds. Among these polymerization initiators, a photopolymerization initiator is preferable from the viewpoint of not leaving a thermal history in the polymer matrix.

[0056] Examples of the photopolymerization initiator include 2,4,6-trimethylbenzoyldiphenylphosphine oxide, 2,2'-bis(o-chlorophenyl)-4,4',5,5'-tetraphenyl-1,1'-biimidazole, 2,4,6-tris(trichloromethyl)-1,3,5-triazine, 2,4-bis(trichloromethyl)-6-(p-methoxyphenylvinyl)-1,3,5-triazine, diphenyliodonium tetrafluoroborate, diphenyliodonium hexafluorophosphate, 4,4'-ditert-butyldiphenylphosphine oxide, and the like. phenyliodonium tetrafluoroborate, 4-diethylaminophenylbenzenediazonium hexafluorophosphate, benzoin, 2-hydroxy-2-methyl-1-phenylpropan-2-one, benzophenone, thioxanthone, 2,4,6-trimethylbenzoyldiphenylacylphosphine oxide, triphenylbutylborate tetraethylammonium, diphenyl-4-phenylthiophenylsulfonium hexafluorophosphate, 2,2-dimethoxy-1,2-diphenylethan-1-one, phenyl Photoradical polymerization initiators such as glyoxylic acid methyl ester, 2-methyl-1-[4-(methylthio)phenyl]-2-morpholinopropan-1-one, bis(2,4,6-trimethylbenzoyl)-phenylphosphine oxide, 1,2-octanedione, 1-[4-(phenylthio)-2-(o-benzoyloxime)], bis(η5-2,4-cyclopentadiene-1-yl)bis[2,6-difluoro-3-(1H-pyrrol-1-yl)phenyltitanium], 2,4,6-tris(trichloromethyl)-1,3 Examples of photo-induced cationic ring-opening polymerization initiators include, but are not limited to, 2,4-bis(trichloromethyl)-6-(p-methoxyphenylvinyl)-1,3,5-triazine, diphenyliodonium tetrafluoroborate, 4,4'-ditert-butyldiphenyliodonium tetrafluoroborate, 4-diethylaminophenylbenzenediazonium hexafluorophosphate, and diphenyl-4-phenylthiophenylsulfonium hexafluorophosphate, but the present disclosure is not limited to these examples. These photo-induced polymerization initiators may be used alone or in combination of two or more.

[0057] When a photopolymerization initiator is used as the polymerization initiator, the amount of the photopolymerization initiator is usually preferably about 0.01 parts by weight to about 20 parts by weight per 100 parts by weight of the total monomers.

[0058] Examples of the thermal polymerization initiator include azo-based polymerization initiators such as azobisisobutyronitrile (AIBN), 2,2'-azobis(methyl isobutyrate), 2,2'-azobis(2,4-dimethylvaleronitrile), 2,2'-azobis(2-methylbutyronitrile), and 1,1'-azobis(cyclohexane-1-carbonitrile), and peroxide-based polymerization initiators such as benzoyl peroxide, potassium persulfate, and ammonium persulfate, but the present disclosure is not limited to these examples.

[0059] When a thermal polymerization initiator is used as the polymerization initiator, the amount of the thermal polymerization initiator is usually preferably about 0.01 parts by weight to about 20 parts by weight per 100 parts by weight of the total monomers.

[0060] When a polymerization initiator that generates nitrogen (N2) during the polymerization reaction, such as AIBN, is used, the resulting composite may contain bubbles. Since such bubbles can be the starting point of breakage, the properties of the composite, such as its extensibility, may be reduced, but it is expected that the impact absorption ability may be improved. The bubbles contained in the composite are not limited to those derived from the polymerization initiator, and may be bubbles obtained by a known method that can include bubbles in a resin, such as those obtained by adding a foaming agent or removing a solvent.

[0061] Other polymerization initiators that can be used in the present disclosure include, for example, redox polymerization initiators such as hydrogen peroxide and iron (II) salt, persulfate and sodium hydrogen sulfite, ATRP (atom transfer radical polymerization) initiators using alkyl halides under metal catalysts, ICAR ATRP initiators and ARGET ATRP initiators using metals and nitrogen-containing ligands, RAFT (reversible addition-fragmentation chain transfer polymerization) agents, NMP (polymerization via nitroxide) agents, polymeric polymerization initiators such as polydimethylsiloxane unit-containing polymeric azo polymerization initiators, and polyethylene glycol unit-containing polymeric azo polymerization initiators, but the present disclosure is not limited to only these examples.

These chain transfer agents may be used alone or in combination of two or more. The amount of the chain transfer agent is not particularly limited, but may usually be about 0.01 to about 10 parts by weight per 100 parts by weight of the total monomers.

[0063] The atmosphere in which the monomer is photopolymerized is not particularly limited, and may be air or an inert gas such as nitrogen gas or argon gas.

[0064] The temperature at which the monomer is photopolymerized is not particularly limited, and is usually preferably about 5 to 100° C. The time required to polymerize the monomer varies depending on the polymerization conditions and cannot be generally determined, so it is optional, but is usually about 1 to 20 hours.

[0065] The polymerization reaction can be terminated at any time when the amount of the remaining monomer becomes 20% by mass or less. The amount of the remaining monomer can be measured, for example, by gel permeation chromatography (GPC).

[0066] By polymerizing the monomers as described above, a polymer matrix can be obtained.

[0067] In one embodiment, the monomers are polymerized in the absence of a crosslinking agent, hi another embodiment, the monomers are polymerized in the presence of a crosslinking agent.

Among these polymerization methods, bulk polymerization and solution polymerization are preferred.

[0070] The polymerization of the monomer can be carried out by, for example, a radical polymerization method, a living radical polymerization method, an anionic polymerization method, a cationic polymerization method, an addition polymerization method, a polycondensation method, a catalytic polymerization method, or the like.

[0071] When the monomer is polymerized by a solution polymerization method, for example, the monomer can be polymerized by dissolving the monomer in a solvent and adding a polymerization initiator to the resulting solution while stirring the solution, or the monomer can be polymerized by dissolving a polymerization initiator in a solvent and adding the monomer to the resulting solution while stirring the solution. The solvent is preferably an organic solvent compatible with the monomer.

[0072] The copolymers included in the conductive material of the present disclosure may be polymerized by using peroxide-based initiators (eg, benzoyl peroxide, and azobisisobutyronitrile, and analogs thereof) as polymerization initiators.

[0073] When the above-mentioned usable polymerization initiators are used as the polymerization initiator, the amount of the polymerization initiator is usually preferably about 0.01 parts by weight to about 20 parts by weight per 100 parts by weight of the total monomers.

In the electron beam polymerization, the electron beam is irradiated in the presence of a photopolymerization initiator in one embodiment, and in the absence of a photopolymerization initiator in another embodiment. Either embodiment is within the scope of the present disclosure.

Usually, the polymerization reaction temperature is about 50°C to about 120°C. The atmosphere during the thermal polymerization reaction is preferably an inert gas atmosphere such as nitrogen gas. The thermal polymerization reaction time of the monomer varies depending on the polymerization reaction temperature and the like and cannot be determined in general, but is usually about 3 to 20 hours.

[0092] (Preferred embodiment) The preferred embodiments of the present disclosure are described below.

Therefore, it is clear that a person skilled in the art can make appropriate modifications within the scope of the present disclosure in light of the description in this specification. It is also understood that the following embodiments of the present disclosure can be used alone or in combination.

[0093] (Applications for improving conductivity) In one aspect, the present disclosure relates to electrical conductivity enhancement applications.

[0094] More specifically, in a specific aspect, the present disclosure provides a composition (conductivity enhancer) or combination for improving the electrical conductivity of an electrical conductor, comprising at least one compound from a group of ether moiety-containing (meth)acrylic monomer components, at least one compound from a group of halogen-containing (meth)acrylic monomer components, and at least one compound from a group of hydroxy-containing (meth)acrylic monomer components.

[0095] In the past, in systems in which a large amount of silver filler is present, as in the present disclosure, it was thought that the polymer composition did not affect the conductivity, and therefore sufficient consideration had not been given to this. However, as a result of polymer consideration, it was confirmed that the resistivity was lower than that of conventional products in a system in which a fluorinated alkyl acrylate, an ether moiety-containing acrylate, and a hydroxyl-containing acrylate were copolymerized. Further investigation confirmed that the resistivity was lower as the fluorine atom content in the fluorinated alkyl acrylate increased. From the viewpoint of resin solubility, it was decided to use 2,2,2-trifluoroethyl acrylate (V#3F) in this system.

[0096] In one specific embodiment, the conductive material of the present disclosure includes a copolymer of an alkoxy-substituted alkyl acrylate, which is an embodiment of an ether moiety-containing (meth)acrylic monomer, a fluorinated alkyl (meth)acrylate, which is an embodiment of a halogen-containing (meth)acrylic monomer, and a hydroxy-containing acrylate, which is an embodiment of a hydroxy-containing (meth)acrylic monomer, and a conductive component. In this way, the copolymer can improve the conductivity of the conductive component.

[0097] By providing this technology of the present disclosure, the conductivity of any conductive component can be improved.

[0098] In one preferred embodiment, the copolymer used in the present disclosure is advantageously a copolymer of an alkoxy-substituted alkyl acrylate, a fluorinated alkyl (meth)acrylate, and a hydroxy-containing acrylate. The reason for this, without wishing to be bound by theory, is the effect of repelling compounds (surface activity effect). Fluorine-based resins are used as antifouling coating agents and release agents, and have the effect of repelling compounds (surface activity effect). As for the reason for the decrease in resistivity in the present disclosure, it is believed that the silver particles are more densely packed together due to the repulsion between the fluorinated alkyl (meth)acrylate and the silver particles caused by the surface activity effect of the fluorine compound. In addition, it is believed that the polarity of the copolymer also affects the decrease in resistivity, and it is believed that these factors have a combined effect, causing the decrease in resistivity. Furthermore, it is an unexpected result that the effect is manifested with a small amount of addition such as in the examples.

[0164] The present disclosure has been described above by showing preferred embodiments for ease of understanding. The present disclosure will be described below based on examples, but the above description and the following examples are provided for illustrative purposes only and are not provided for the purpose of limiting the present disclosure. Therefore, the scope of the present disclosure is not limited to the embodiments or examples specifically described in this specification, but is limited only by the scope of the claims. EXAMPLES

[0165] Examples are described below. The handling of the organisms used in the following examples complied with standards stipulated by regulatory agencies, if necessary. The specific reagents used were the products described in the examples, but equivalent products from other manufacturers (Sigma-Aldrich, etc.) can also be used.

[0166] Example A: Preparation of polymer matrix In this example, a polymer matrix was prepared.

[0167] Example 1 2-Methoxyethyl acrylate (62 g, manufactured by Osaka Organic Chemical Industry Co., Ltd., trade name 2-MTA) as monomer A, 2,2,2-trifluoroethyl acrylate (36 g, manufactured by Osaka Organic Chemical Industry Co., Ltd., trade name Viscoat V#3F) as monomer B, 4-hydroxybutyl acrylate (1 g, manufactured by Osaka Organic Chemical Industry Co., Ltd., trade name Viscoat 4-HBA) as monomer C, 2,4,6-trimethylbenzoyldiphenylphosphine oxide (1 g, manufactured by BASF, trade name Irgacure (registered trademark) TPO) as a polymerization initiator, and α-methylstyrene dimer (1 g, manufactured by NOF Corporation, trade name Nofumer MSD) as a chain transfer agent were mixed to obtain a monomer component containing a polymerization initiator. The obtained monomer component was poured into a transparent glass mold (length: 100 mm, width: 100 mm, depth: 2 mm), and then the monomer component was exposed to an irradiation dose of 0.36 mW / cm. 2 The monomer components were irradiated with ultraviolet light so that the temperature reached 100° C., and the monomer components were bulk polymerized for 2 hours to obtain a polymer.

[0168] Preparation of conductive material precursor The resulting polymer (2.50 g) was dissolved in 3-methoxy-3-methyl-1-butanol (7.50 g) to obtain a resin solution. The above resin solution (4.00 g) was mixed with silver filler (4.00 g, manufactured by Fukuda Metal Foil & Powder Co., Ltd., product name AgC-A), a crosslinking agent (0.010 g, manufactured by Asahi Kasei Corporation, product name MF-K60B), 2-(2-butoxyethoxy)ethanol (0.10 g) as a dispersant, and a rheology modifier (0.010 g, manufactured by Big-Chemie Japan, product name RHEOBYK-410) using a Mazerustar manufactured by Kurabo Industries, to obtain a conductive material precursor.

[0169] (paint film formation) The obtained conductive material precursor was applied to a release polyethylene terephthalate film (manufactured by Mitsui Chemicals Tocello Inc., product name Separator SP-PET PET-01-Bu) as a release film to form a coating film.

[0170] (Conductive film) The resulting coating was heated in an oven at 120° C. for 30 minutes to obtain a conductive film having a thickness of approximately 40 μm.

[0171] (Examples 2 to 4) An acrylic resin solution was obtained in the same manner as in Example 1, except that the ratios of monomer A, monomer B, monomer C and the crosslinking agent were changed as shown in the table below.

[0172] Example 5 An acrylic resin solution was obtained in the same manner as in Example 1, except that ethyl acrylate (EA, 31 g) was newly added as monomer D, and 2-methoxyethyl acrylate (31 g, manufactured by Osaka Organic Chemical Industry Co., Ltd., product name 2-MTA) as monomer A, 2,2,2-trifluoroethyl acrylate (36 g, manufactured by Osaka Organic Chemical Industry Co., Ltd., product name Viscoat V#3F) as monomer B, 4-hydroxybutyl acrylate (1 g, manufactured by Osaka Organic Chemical Industry Co., Ltd., product name Viscoat 4-HBA) as monomer C, isocyanate (1 g) as a crosslinking agent, and 2,4,6-trimethylbenzoyldiphenylphosphine oxide (1 g, manufactured by BASF, product name Irgacure (registered trademark) TPO) as a polymerization initiator were mixed in the above amounts.

[0173] (Comparative Examples 1 and 2) The corresponding polymer was obtained by using only 2-MTA (monomer A) and V#3F (monomer B) as monomers. The weight parts of the compositions of the monomers A and B used are as shown in Table 1.

[0174] Comparative Example 3 Similarly, the corresponding polymer was obtained using V#3F (monomer B), 4-HBA (monomer C) and isocyanate (crosslinking agent). The weight parts of the monomer B, monomer C and crosslinking agent used are as shown in Table 1.

[0175] Comparative Example 4 Similarly, the corresponding polymer was obtained using V#3F (monomer B), 4-HBA (monomer C), isocyanate (crosslinker) and EA (monomer D). The weight parts of the monomer B, monomer C and crosslinker used are as shown in Table 1.

[0176] Example B: Preparation of Conductive Film In this example, a conductive film was prepared.

[0177] (Conductive material precursor) Each acrylic resin solution (6.00 g) obtained in Example A was mixed with silver filler (7.20 g, manufactured by Fukuda Metal Foil & Powder Co., Ltd., product name AgC-A) and 2-(2-butoxyethoxy)ethanol (0.10 g) as a dispersant using a Mazerustar manufactured by Kurabo Industries Co., Ltd. to obtain a conductive material precursor.

[0178] (paint film formation) The obtained conductive material precursor was applied to a release polyethylene terephthalate film (manufactured by Mitsui Chemicals Tocello Inc., product name Separator SP-PET PET-01-Bu) as a release film to form a coating film.

[0179] (Conductive film) The resulting coating was heated in an oven at 120° C. for 30 minutes to obtain a conductive film having a thickness of approximately 40 μm.

[0180] (result) Conductive films were prepared according to the procedures described in Examples A and B. The results are shown in Table 1. [Table 1]

[0181] (Example C: Measurement of volume resistivity) The conductive film obtained in Example B was cut into a piece having a length of 0.5 cm and a width of 2.00 cm, and was measured by a four-terminal method using Loresta GP (manufactured by Mitsubishi Chemical Analytech Co., Ltd.).

[0182] (result) The results are shown in Table 1.

[0183] (Example D: Confirmation of change in resistance value) In this embodiment, the change in resistance value was confirmed.

[0184] (Resistance measurement) The conductive film obtained above was cut into a piece having a length of 0.5 cm and a width of 2.00 cm, and the resistance value (ΩA) before stretching was measured using a digital multimeter (manufactured by Sanwa Denki Keiki Co., Ltd., product name PC773) with the interelectrode distance fixed at 1.00 cm.

[0185] (Resistance change) Next, while the conductive film was fixed on the multimeter electrodes, the distance between the electrodes was set to 2.00 cm, and the resistance value (ΩB) in this state was measured. The change in resistance value was calculated as follows. Resistance change = ΩB / ΩA

[0186] (result) The results are shown in Table 1. The smaller the change in resistance value (closer to 1), the smaller the effect of the shape change, which means higher durability. Therefore, the change in resistance value can also be evaluated as durability.

[0187] Example E: Measurement of Flexibility The conductive film obtained in the above example was cut into a test piece (dumbbell-shaped No. 7). The flexibility of this test piece was measured at a tension speed of 50 mm / min using a tensile tester (manufactured by A&D Co., Ltd.: product name TENSILON RTG-1310). Young's modulus was calculated from the obtained value.

[0188] (result) The results are shown in Table 1.
