Abstract
Description
[Technical Field]
[0001] This disclosure relates to polymers. [Background technology]
[0002] Conventionally, technologies have been studied that impart functions such as stain resistance by applying a surface treatment agent to a substrate. For example, in applications requiring high transparency, such as screen protection for mobile devices, it is desirable to treat the surface with a thin film having a thickness of one to several molecules. As surface treatment agents that can form thin films, silane coupling agents consisting of alkylsilanes, or polymers mainly composed of alkyl acrylates or alkyl methacrylates have been used (for example, Patent Document 1).

[0165] The above-mentioned coating agent is, for example, a coating agent for electronic equipment. That is, the above-mentioned coating agent is used to waterproof and / or moisture-proof the surface of electronic equipment. Furthermore, the above-mentioned coating agent can also be used as an antifouling coating agent.
[0166] [Goods] The articles of this disclosure include a layer or film formed from a composition (e.g., a surface treatment agent, a waterproofing and / or moisture-proofing coating agent). That is, the articles of this disclosure include an object to be treated and a layer or film formed from the polymer of this disclosure on the surface of the object to be treated. The layer or film may cover the entire object to be treated or only a part of it.
[0167] [Use as a surface treatment agent] In one embodiment, the article of the present disclosure includes a layer formed from the surface treatment agent. That is, the article of this embodiment includes a substrate and a layer (surface treatment layer) formed on the surface of the substrate from a surface treatment agent containing the polymer of the present disclosure.
[0168] The substrates usable in this embodiment may consist of any suitable material, such as glass, resin (natural or synthetic resin, such as a common plastic material, which may be in the form of a sheet, film, or other), metal, ceramic, semiconductor (silicon, germanium, etc.), fiber (textile, nonwoven fabric, etc.), fur, leather, wood, ceramics, stone, building materials, etc.
[0169] For example, if the article to be manufactured is an optical component, the material constituting the surface of the substrate may be an optical component material, such as glass or transparent plastic. Also, if the article to be manufactured is an optical component, some layer (or film), such as a hard coat layer or an anti-reflective layer, may be formed on the surface (outermost layer) of the substrate. Either a single-layer anti-reflective layer or a multi-layer anti-reflective layer may be used for the anti-reflective layer. Examples of inorganic materials that can be used for the anti-reflective layer include SiO2, SiO, ZrO2, TiO2, TiO, Ti2O3, Ti2O5, Al2O3, Ta2O5, CeO2, MgO, Y2O3, SnO2, MgF2, and WO3. These inorganic materials may be used individually or in combination of two or more (for example, as a mixture). When a multi-layer anti-reflective layer is used, it is preferable to use SiO2 and / or SiO for the outermost layer. If the article to be manufactured is an optical glass component for a touch panel, a thin film using a transparent electrode, such as indium tin oxide (ITO) or indium zinc oxide, may be present on a portion of the surface of the substrate (glass). Furthermore, depending on its specific specifications, the substrate may have an insulating layer, an adhesive layer, a protective layer, a decorative frame layer (I-CON), an atomizing film layer, a hard coating film layer, a polarizing film, a phase difference film, and a liquid crystal display module.
[0170] The shape of the substrate is not particularly limited. Furthermore, the surface area of the substrate on which the surface treatment layer is to be formed only needs to be at least a part of the substrate surface and can be appropriately determined according to the intended use and specific specifications of the article to be manufactured.
[0171] Such a substrate may consist of a material that originally contains hydroxyl groups, at least on its surface. Examples of such materials include glass, as well as metals (especially base metals) on which a native oxide film or thermal oxide film is formed on the surface, ceramics, semiconductors, etc. Alternatively, if the material does not have enough hydroxyl groups, such as resins, or if it does not originally contain hydroxyl groups, the substrate can be pretreated to introduce or increase hydroxyl groups on its surface. Examples of such pretreatment include plasma treatment (e.g., corona discharge) and ion beam irradiation. Plasma treatment can introduce or increase hydroxyl groups on the substrate surface and can also be suitably used to clean the substrate surface (remove foreign matter, etc.). Another example of such pretreatment is a method in which an interfacial adsorbent having carbon-carbon unsaturated bond groups is formed in the form of a monolayer on the substrate surface by the LB method (Langmuir-Bludget method) or chemical adsorption method, and then the unsaturated bonds are cleaved in an atmosphere containing oxygen or nitrogen.
[0172] Alternatively, such a substrate may consist of a material in which at least its surface portion is made of another reactive group, such as a silicone compound having one or more Si-H groups, or an alkoxysilane.
[0173] Next, a layer formed from the surface treatment agent of the present disclosure is provided on the surface of the substrate, and this layer is post-treated as necessary, thereby forming a layer from the surface treatment agent of the present disclosure.
[0174] The layer formation of the surface treatment agent in this embodiment can be carried out by applying the above-mentioned surface treatment agent to the surface of the substrate so as to cover the surface. The coating method is not particularly limited. For example, a wet coating method and a dry coating method can be used.
[0175] Examples of wet coating methods include immersion coating, spin coating, flow coating, spray coating, roll coating, gravure coating, and similar methods.
[0176] Examples of dry coating methods include vapor deposition (usually vacuum deposition), sputtering, CVD, and similar methods. Specific examples of vapor deposition methods (usually vacuum deposition) include resistance heating, electron beams, high-frequency heating using microwaves, ion beams, and similar methods. Specific examples of CVD methods include plasma-CVD, optical CVD, thermal CVD, and similar methods.
[0177] Furthermore, coating using the atmospheric pressure plasma method is also possible.

These solvents can be used individually or as mixtures of two or more.Among these, aliphatic hydrocarbons, esters, glycol ethers, alcohols, ether alcohols, and siloxanes are preferred. For example, hexane, cyclohexane, heptane, octane, nonane, decane, undecane, dodecane, mineral spirits, methyl acetate, ethyl acetate, propyl acetate, n-butyl acetate, isopropyl acetate, isobutyl acetate, propylene glycol monomethyl ether, propylene glycol monoethyl ether, propylene glycol monobutyl ether, methanol, ethanol, iso-propanol, n-butanol, isobutanol, tert-butanol, sec-butanol, diethylene glycol monomethyl ether, hexamethyldisiloxane, hexaethyldisiloxane, octamethyltrisiloxane, decamethyltetrasiloxane, dodecamethylpentasiloxane, tetradecamethylhexasiloxane, octamethylcyclotetrasiloxane, and octamethylcyclopentasiloxane are particularly preferred. Preferably, the same solvent as the solvent of the surface treatment agent of this disclosure is used as the solvent used in the wet coating method.
[0179] When using the dry coating method, the surface treatment agent of this disclosure may be subjected to the dry coating method as is, or it may be diluted with the solvent described above before being subjected to the dry coating method.
[0180] From the viewpoint of good dispersibility, the surface treatment agent of this embodiment can be effectively used in wet coating methods, particularly in spray coating.
[0181] The layer formation of the surface treatment agent is preferably carried out such that the surface treatment agent of the present disclosure is present in the layer together with a catalyst for hydrolysis and dehydration condensation. For convenience, in the case of a wet coating method, the surface treatment agent of the present disclosure may be diluted with a solvent, and the catalyst may be added to the diluted solution of the surface treatment agent of the present disclosure immediately before application to the substrate surface. In the case of a dry coating method, the surface treatment agent of the present disclosure with the catalyst added may be directly vapor-deposited (usually by vacuum deposition), or a pelletized material in which the surface treatment agent of the present disclosure with the catalyst added may be impregnated, such as iron or copper, may be vapor-deposited (usually by vacuum deposition).

[0183] As described above, a layer derived from the surface treatment agent of the present disclosure is formed on the surface of the substrate, and an article of the present disclosure is manufactured. The resulting layer has both high surface slipperiness and high friction resistance. In addition to high friction resistance, the layer may also have water repellency, oil repellency, stain resistance (e.g., preventing the adhesion of dirt such as fingerprints), waterproofness (preventing water from entering electronic components, etc.), and surface slipperiness (or lubricity, e.g., ease of wiping away dirt such as fingerprints and excellent tactile feel to the fingers), depending on the composition of the surface treatment agent used, and can be suitably used as a functional thin film.
[0184] In other words, this embodiment further relates to an optical material having the above-mentioned surface treatment layer as its outermost layer.
[0185] As optical materials, a wide variety of optical materials are preferred, in addition to optical materials related to displays, as exemplified below: for example, displays such as cathode ray tubes (CRTs; e.g., PC monitors), liquid crystal displays, plasma displays, organic EL displays, inorganic thin-film EL dot matrix displays, rear projection displays, fluorescent display tubes (VFDs), field emission displays (FEDs), or protective plates for such displays, or materials on which an anti-reflective coating has been applied to their surface.
[0186] Articles having the layer obtained by this embodiment are not particularly limited, but may be optical components. Examples of optical components include: lenses such as those in eyeglasses; front protective plates, anti-reflective plates, polarizing plates, and anti-glare plates for displays such as PDPs and LCDs; touch panel sheets for devices such as mobile phones and personal digital assistants; disc surfaces of optical discs such as Blu-ray (registered trademark) discs, DVD discs, CD-Rs, and MOs; optical fibers; and display surfaces of watches.

Examples of exterior components include: windows, light covers, and aftermarket camera covers. Examples of interior components include: instrument panel covers, navigation system touch panels, and decorative interior components.
[0189] The thickness of the above layer is not particularly limited. In the case of optical components, the thickness of the above layer is preferably in the range of 1 to 50 nm, 1 to 30 nm, and more preferably 1 to 15 nm, from the viewpoint of optical performance, surface slipperiness, frictional durability, and antifouling properties.
[0190] In one embodiment, the article of the present disclosure may include an intermediate layer containing silicon oxide between the glass and the surface treatment layer. By providing such an intermediate layer, the adhesion between the glass and the surface treatment layer is improved, and the durability is improved.
[0191] The thickness of the intermediate layer is not particularly limited, but is preferably 1 to 200 nm, and particularly preferably 1 to 20 nm. By setting the thickness of the intermediate layer to be above the lower limit of the above range, the effect of improving adhesion by the intermediate layer becomes greater.
[0192] [Use as a coating agent for waterproofing and / or moisture-proofing] In one embodiment, the article of the present disclosure includes a film formed from the waterproof and / or moisture-proof coating agent. The article of this embodiment includes an object to be treated and a film formed on the surface of the object to be treated from a coating agent containing the polymer of the present disclosure. A layer may be used instead of a film formed from the coating agent.
[0193] The coating agent of this embodiment provides excellent waterproofing and / or moisture-proofing performance, and the film formed from the coating agent also exhibits good durability, such as abrasion resistance. Therefore, when electronic components are the target of the treatment, it is possible to provide good waterproofing and / or moisture-proofing performance without impairing their performance. This significantly reduces the possibility of failure in treated objects that may get wet (e.g., electronic equipment).
[0194] The articles in this embodiment can be effectively used to apply a waterproof and / or moisture-proof coating to components such as the casings and printed circuit boards of electronic devices that may malfunction when exposed to liquids such as water. For example, by applying the coating to the casing, it is possible to prevent water from entering the inside of the casing, and by applying the coating to components such as printed circuit boards, it is possible to suppress the adhesion of water even if water does enter the inside of the casing, and furthermore, the adhered water can be easily removed by drying, thereby greatly reducing the possibility of malfunctions caused by water.
[0195] Examples of electronic devices that may get wet include portable electronic devices such as smartphones, tablet PCs, portable music players, portable radios, IC recorders, and wireless audio receivers; and measuring instruments used in water-related or seawater environments, such as fish finders, depth sounders, radiation detectors, residual chlorine meters, salinity meters, spectrometers, and refractometers. In particular, when processing electronic components including substrates and semiconductors, using a waterproofing and / or moisture-proofing coating agent makes it possible to form a highly durable waterproof and moisture-proof film using a solvent with low chemical erosion properties, thereby providing good waterproofing and moisture-proofing performance without impairing the performance of the electronic components.
[0196] The coating agent of this embodiment can be applied not only to the electronic components described above, but also to fuel cells, particularly membrane electrode assemblies (MEAs); elements such as organic electroluminescent (EL) or light-emitting diode (LED) lighting; biochips, particularly substrates for medical microfluidic channels, etc.
[0197] The treatment method using the coating agent of this embodiment is not particularly limited, and any method that allows sufficient contact between the polymer of this disclosure and the object to be treated is acceptable. For example, various methods such as vapor deposition, immersion, spray coating, brush coating, and spin coating can be applied.
[0198] For example, in the case of immersion, the object to be treated is usually immersed in the coating agent of this embodiment and then dried in the air. There are no particular limitations on the temperature during immersion, and the treatment is usually carried out at room temperature. There are also no particular limitations on the treatment time, but the immersion time is usually between 1 second and 24 hours.
[0199] To form a coating with higher durability, it is preferable to wash the substrate surface with acetone, ethanol, isopropyl alcohol, hydrofluoroether, hydrofluoroolefin, etc., to remove oil from the substrate surface before treatment with the coating agent of this embodiment, and then dry it. Furthermore, in addition to the above washing, pretreatment with UV ozone, atmospheric pressure plasma, oxygen plasma, etc., can further improve the durability of the coating compared to when it is untreated.
[0200] Unless otherwise specified, the materials (e.g., solvents, etc.) and physical properties (e.g., film thickness, etc.) that can be used in this embodiment may be those described above as surface treatment agents.
