[0002] This invention relates to compositions containing silane compounds with perfluoro(poly)ether groups, and more particularly, to compositions containing silane compounds with perfluoro(poly)ether groups and acids or acid derivatives with perfluoro(poly)ether groups. Background Technology

[0003] It is known that certain fluorinated silane compounds, when used for surface treatment of substrates, can provide excellent water-repellent, oil-repellent, and stain-resistant properties. Layers obtained from surface treatment agents containing fluorinated silane compounds (hereinafter also referred to as "surface treatment layers") are applied as so-called functional films to a wide variety of substrates, such as glass, plastics, fibers, and building materials.

[0004] As such fluorinated silane compounds, there are known silane compounds containing perfluoropolyether groups that have perfluoropolyether groups in the main molecular chain and hydrolyzable groups bonded to Si atoms at the molecular ends or terminal portions. For example, Patent Documents 1 and 2 describe silane compounds containing perfluoropolyether groups that have hydrolyzable groups bonded to Si atoms at the molecular ends or terminal portions.

[0818] The compositions of the present invention can be impregnated in porous materials, such as porous ceramic materials, metal fibers, or materials such as steel wool aggregated into a cotton-like form, to form granules. These granules can be used, for example, in vacuum evaporation.

[0819] The compositions of the present invention can impart water-repellent, oil-repellent, stain-resistant, water-repellent, and high friction durability to substrates, and therefore can be well used as surface treatment agents. Specifically, the compositions of the present invention are not particularly limited and can be well used as stain-resistant or water-repellent coatings.

[0820] Next, the article of the present invention will be described.

[0821] The article of the present invention includes a substrate and a layer (surface treatment layer) formed on the surface of the substrate by the composition of the present invention. The article can be manufactured, for example, by the following operations.

[0822] First, prepare the substrate. The substrate that can be used in this invention can be made of any suitable material, such as glass, sapphire glass, resin (which can be natural or synthetic resin, such as general plastic materials, and can be in the form of plates, films, or other forms), metal (which can be a composite of elemental metals such as aluminum, copper, and iron, or alloys), ceramics, semiconductors (silicon, germanium, etc.), fibers (fabric, non-woven fabrics, etc.), fur, leather, wood, ceramics, stone, building components, etc.

[0823] As for the aforementioned glass, soda-lime glass, alkali aluminosilicate glass, borosilicate glass, alkali-free glass, crystal glass, and quartz glass are preferred, with chemically strengthened soda-lime glass, chemically strengthened alkali aluminosilicate glass, and chemically bonded borosilicate glass being particularly preferred.

[0824] Acrylic resin and polycarbonate are preferred as resins.

[0825] For example, when the article to be manufactured is an optical component, the material constituting the surface of the substrate can be a material used for optical components, such as glass or transparent plastic. Alternatively, when the article to be manufactured is an optical component, a layer (or film), such as a hard coating or an anti-reflective layer, can be formed on the surface (outermost layer) of the substrate. The anti-reflective layer can be either a single-layer or multi-layer anti-reflective layer. Examples of inorganic materials that can be used in anti-reflective layers include SiO2, SiO, ZrO2, TiO2, TiO, Ti2O3, Ti2O5, Al2O3, Ta2O5, CeO2, MgO, Y2O3, SnO2, MgF2, and WO3. These inorganic materials can be used alone or in combination of two or more (e.g., as a mixture). When forming a multi-layer anti-reflective layer, it is preferable to use SiO2 and / or SiO in its outermost layer. When the item to be manufactured is an optical glass component for a touch panel, a transparent electrode can be formed on a portion of the surface of the substrate (glass), such as a thin film using indium tin oxide (ITO) or indium zinc oxide. Furthermore, depending on its specific specifications, the substrate can have insulating layers, adhesive layers, protective layers, decorative frame layers (I-CON), atomizing film layers, hard coating layers, polarizing films, retardation films, and liquid crystal display components, etc.

[0826] There are no particular limitations on the shape of the substrate. In addition, the surface area of ​​the substrate to which the surface treatment layer should be formed only needs to be at least a portion of the substrate surface, which can be appropriately determined according to the intended use and specific specifications of the article to be manufactured.

[0827] Such a substrate can be a material that originally has hydroxyl groups, at least in part on its surface. Examples of such materials include glass, as well as metals (especially base metals), ceramics, semiconductors, etc., on which a natural or thermal oxide film forms. Alternatively, when the substrate, such as resin, has hydroxyl groups but not sufficiently, or does not originally have hydroxyl groups, hydroxyl groups can be introduced or added to the surface of the substrate through some pretreatment. Examples of such pretreatments include plasma treatment (e.g., corona discharge) and ion beam irradiation. Plasma treatment can introduce or add hydroxyl groups to the surface of the substrate, and can also be suitably used to clean the surface of the substrate (removing foreign matter, etc.). Another example of such pretreatment is a method in which an interfacial adsorbent having carbon-carbon unsaturated bonding groups is pre-formed on the surface of the substrate as a monolayer using the LB method (Langmuir-Blodgett method) or chemisorption method, and then the unsaturated bonds are broken in an atmosphere containing oxygen, nitrogen, etc.

[0828] Alternatively, such a substrate may be a substrate whose surface portion is formed of other reactive groups, such as organosilicon compounds having one or more Si-H groups, or materials containing alkoxysilanes.

[0829] Next, a film of the composition of the present invention is formed on the surface of this substrate, and the film is post-treated as needed, thereby forming a surface treatment layer from the composition of the present invention.

[0830] The film formation of the composition of the present invention can be carried out by applying the composition of the present invention to the surface of a substrate in a manner that covers the surface. The covering method is not particularly limited. For example, wet covering and dry covering methods can be used.

[0831] Examples of wet coating methods include dip coating, spin coating, flow coating, spray coating, roller coating, gravure coating, and similar methods.

[0832] Examples of dry coating methods include vapor deposition (typically vacuum vapor deposition), sputtering, CVD, and similar methods. Specific examples of vapor deposition methods (typically vacuum vapor deposition) include resistance heating, electron beam, high-frequency heating using microwaves, ion beam, and similar methods. Specific examples of CVD methods include plasma-CVD, optical CVD, thermal CVD, and similar methods.

[0833] Alternatively, atmospheric pressure plasma can also be used for coverage.

[0834] When using the wet coating method, the compositions of the present invention can be diluted with a solvent and applied to the surface of a substrate. From the viewpoint of the stability of the compositions of the present invention and the volatility of the solvent, the following solvent is preferred: C5－12 Perfluoroaliphatic hydrocarbons (e.g., perfluorohexane, perfluoromethylcyclohexane, and perfluoro-1,3-dimethylcyclohexane); polyfluorinated aromatic hydrocarbons (e.g., bis(trifluoromethyl)benzene); polyfluorinated aliphatic hydrocarbons (e.g., C6F... 13 CH2CH3 (e.g., ASAHIKLIN AC-6000 manufactured by Asahi Glass Co., Ltd.), 1,1,2,2,3,3,4-heptafluorocyclopentane (e.g., ZEORORA H manufactured by ZEON Corporation, Japan); hydrofluorocarbons (HFCs) (e.g., 1,1,1,3,3-pentafluorobutane (HFC-365mfc)); hydrochlorofluorocarbons (e.g., HCFC-225 (ASAHIKLIN AK225)); hydrofluoroethers (HFEs) (e.g., perfluoropropyl methyl ether (C3F7OCH3) (e.g., Novec 7000 manufactured by Sumitomo 3M Co., Ltd.), perfluorobutyl methyl ether (C4F9OCH3) Alkyl perfluoroalkyl ethers (perfluoroalkyl and alkyl groups can be straight-chain or branched), such as Novec 7100 (manufactured by Sumitomo 3M Corporation), perfluorobutyl ether (C4F9OC2H5) (e.g., Novec 7200 (manufactured by Sumitomo 3M Corporation), perfluorohexyl ether (C2F5CF(OCH3)C3F7) (e.g., Novec 7300 (manufactured by Sumitomo 3M Corporation), or CF3CH2OCF2CHF2 (e.g., ASAHIKLIN AE-3000 (registered trademark) manufactured by Asahi Glass Co., Ltd.), 1,2-dichloro-1,3,3,3-tetrafluoro-1-propene (e.g., Vertrel SION (registered trademark) manufactured by Mitsui & Dupon Fluoro Chemical Co., Ltd.). These solvents can be used alone or in combination of two or more as a mixture. In addition, it can be mixed with other solvents, for example, to adjust the solubility of silane compounds containing perfluoro(poly)ether groups and perfluoropolyether modified compounds.

[0835] When using the drying and covering method, the composition of the present invention can be used directly in the drying and covering method, or it can be used in the drying and covering method after being diluted with the solvent described above.

[0836] Membrane formation is preferably carried out in a manner in which the composition of the present invention is present in the membrane together with a catalyst for hydrolysis and dehydration condensation. Simply put, when using the wet coating method, the composition of the present invention can be diluted with a solvent, and the catalyst can be added to the diluted solution of the composition of the present invention just before application to the substrate surface. When using the dry coating method, the composition of the present invention with the catalyst added can be directly vapor-deposited (typically, vacuum vapor-deposited), or a granular material containing the composition of the present invention with the catalyst added, impregnated in a porous metal such as iron or copper, can be vapor-deposited (typically, vacuum vapor-deposited).

[0837] The catalyst can be any suitable acid or base. Examples of acid catalysts include acetic acid, formic acid, and trifluoroacetic acid. Examples of base catalysts include ammonia and organic amines.

[0838] Next, the membrane is post-treated as needed. This post-treatment is not particularly limited; for example, it can involve sequential water supply and drying heating. More specifically, it can be performed as follows.

[0839] After forming the film of the composition of the present invention on the surface of the substrate as described above, moisture is supplied to the film (hereinafter also referred to as the "precursor film"). The method of supplying moisture is not particularly limited, and methods such as condensation utilizing the temperature difference between the precursor film (and the substrate) and the surrounding atmosphere, or blowing water vapor can be used.

[0840] The supply of moisture can be carried out in an atmosphere, for example, 0–250°C, preferably 60°C or higher, more preferably 100°C or higher, preferably 180°C or lower, and more preferably 150°C or lower. By supplying moisture within this temperature range, hydrolysis can be carried out. The pressure at this time is not particularly limited, and can be simply set to atmospheric pressure.

[0841] Next, the precursor film is heated on the surface of the substrate in a dry atmosphere exceeding 60°C. The drying and heating method is not particularly limited; the precursor film and substrate can be placed together in an atmosphere with a temperature exceeding 60°C, preferably exceeding 100°C, and for example, below 250°C, preferably below 180°C, and with an unsaturated water vapor pressure. The pressure at this time is not particularly limited; simply put, it can be set to atmospheric pressure.

[0842] In this atmosphere, the hydrolyzed Si-bound groups of the silane compounds containing perfluoro(poly)ether groups of the present invention rapidly dehydrate and condense with each other. Furthermore, between such compounds and the substrate, the Si-bound groups of the hydrolyzed compounds react rapidly with reactive groups present on the substrate surface; dehydration condensation occurs when the reactive groups present on the substrate surface are hydroxyl groups. As a result, bonds are formed between the silane compounds containing perfluoro(poly)ether groups and the substrate.

[0843] The aforementioned water supply and drying heating can be carried out continuously using superheated steam.

[0844] Post-treatment can be performed as described above. Such post-treatment can be performed to further improve friction durability, but it should be noted that it is not necessary for manufacturing the articles of the present invention. For example, after applying the composition of the present invention to the surface of a substrate, it may simply be left to stand as is.

[0845] As described above, a surface treatment layer of the film derived from the composition of the present invention is formed on the surface of a substrate, thereby manufacturing the article of the present invention. The resulting surface treatment layer exhibits high friction durability. In addition to high friction durability, depending on the composition used, this surface treatment layer may also possess properties such as water repellency, oil repellency, stain resistance (e.g., prevention of fingerprint adhesion), and surface slipperiness (or lubrication, such as the ability to wipe away fingerprints, and excellent tactile feel for fingers), and can be suitably used as a functional film.

[0846] In other words, the present invention also relates to optical materials having the above-mentioned cured material in the outermost layer.

[0847] As optical materials, in addition to the optical materials for displays and the like described below, a wide variety of optical materials can be listed: for example, displays such as cathode ray tubes (CRTs; for example, TVs, computer monitors), liquid crystal displays, plasma displays, organic EL displays, inorganic thin-film EL dot matrix displays, rear projection displays, fluorescent tubes (VFDs), field emission displays (FEDs), or protective plates for these displays, or optical materials on which anti-reflective coatings have been applied to their surfaces.

[0848] Articles having the surface treatment layer obtained by the present invention are not particularly limited and can be optical components. Examples of optical components include: lenses for eyeglasses, etc.; front protective panels, anti-reflective panels, polarizing panels, and anti-glare panels for displays such as PDPs and LCDs; touch panels for devices such as mobile phones and portable information terminals; disc surfaces for optical discs such as Blu-ray discs, DVD discs, CD-Rs, and MOs; and optical fibers.

[0849] In addition, articles having a surface treatment layer obtained by the present invention can also be medical devices or medical materials.

[0850] The thickness of the surface treatment layer is not particularly limited. When it is an optical component, considering optical performance, surface smoothness, friction durability and anti-fouling properties, the thickness of the surface treatment layer is preferably in the range of 1 to 50 nm, more preferably 1 to 30 nm, and more preferably 1 to 15 nm.

[0851] The articles obtained using the compositions of the present invention have been described in detail above. Furthermore, the uses, methods of use, and methods of manufacturing the articles of the present invention are not limited to the examples described above.

[0852] Example

[0853] The compositions of the present invention are specifically described through the following examples, but the present invention is not limited to these examples. Furthermore, in these examples, all chemical formulas shown below represent average compositions, and the order of the repeating units (CF2CF2CF2O) constituting the perfluoropolyether is arbitrary.

The layer was then washed with a 3-equivalent hydrochloric acid aqueous solution. Next, 30g of anhydrous magnesium sulfate was added to the perfluorohexane layer, stirred, and the insoluble matter was separated by filtration. Then, volatile components were removed by distillation under reduced pressure, thereby obtaining 476g of the perfluoropolyether-modified methyl ester (A) with methyl ester groups at the ends.

[0869] Example 1

[0870] The perfluoropolyether modified methyl ester compound (A) obtained in the above synthesis example 1 and the perfluoropolyether modified silane compound (X) shown below were mixed at a molar ratio of 2:98 and dissolved in Novec 7200 (manufactured by 3M) to prepare surface treatment agent 1 at a concentration of 20 wt%.

[0873] The surface treatment agent 1 prepared above was vacuum-deposited onto chemically strengthened glass (Corning, "Gorilla" glass, 0.7 mm thick). The vacuum deposition conditions were set to a pressure of 3.0 × 10⁻⁶. －3 First, silicon dioxide is deposited onto the surface of the chemically strengthened glass at a thickness of 7 nm using electron beam evaporation to form a silicon dioxide film. Next, 2 mg of a surface treatment agent is deposited onto each piece of chemically strengthened glass (55 mm × 100 mm). Then, the chemically strengthened glass with the deposited film is left to stand for 24 hours at 20°C and 65% humidity. This allows the deposited film to solidify, forming a surface treatment layer.

[0881] In addition to using the above-mentioned perfluoropolyether modified silane compounds (X) to (Z) alone, the surface treatment agent was prepared in the same manner as in Example 1 to form a surface treatment layer.

[0884] Comparative Example 4

[0885] A surface treatment agent was prepared by mixing acetic acid with the above-mentioned perfluoropolyether modified silane compound (X) at a molar ratio of 2:98. Otherwise, the same procedure as in Example 1 was followed to prepare the surface treatment agent and form a surface treatment layer.

[0886] The surface treatment layers formed on the substrate surface in Examples 1-9 and Comparative Examples 1-4 were evaluated for friction durability using a rubber friction durability test. Specifically, the sample with the surface treatment layer was placed horizontally, and a rubber (manufactured by KOKUYO Co., Ltd., KESHI-70, planar dimensions 1cm × 1.6cm) was brought into contact with the surface of the surface treatment layer. A load of 500gf was applied, and then the rubber was moved back and forth at a speed of 20mm / s under the applied load. The static contact angle of water (degrees) was measured every 500 cycles. The evaluation was stopped when the measured contact angle was less than 100 degrees. Table 3 shows the number of cycles when the final contact angle exceeded 100 degrees.

[0889] Based on the above results, it was confirmed that Examples 1-9, which combined silane compounds containing perfluoro(poly)ether groups and perfluoropolyether modified compounds, exhibited higher rubber resistance compared to Comparative Examples 1-3, which used silane compounds containing perfluoro(poly)ether groups alone. While the present invention is not limited by any theory, it can be considered that the perfluoropolyether modified compounds (A)-(C) act as acidic catalysts during the fabrication of the surface treatment layer, enhancing the reactivity of the silane compounds (X)-(Z) containing perfluoro(poly)ether groups with the substrate surface, resulting in excellent rubber durability. Furthermore, it was confirmed that Example 4, which used a perfluoropolyether modified carboxylic acid compound (B), exhibited higher rubber resistance compared to Comparative Example 4, which used acetic acid as a catalyst. While the present invention is not limited by any theory, it can be considered that the presence of perfluoropolyether groups in the acid itself contributes to the function of the surface treatment layer.

[0890] Industrial availability

[0891] The present invention can be suitably used to form surface treatment layers on a wide variety of substrates, especially on the surfaces of optical components that require transparency.
