[Effects of the Invention]

[0006] According to this disclosure, it is possible to provide a laminate having a water-repellent layer with better water repellency, slipperiness, and abrasion resistance. [Modes for carrying out the invention]

[0007] In this specification, "monovalent organic group" means a monovalent group containing carbon. Monovalent organic groups are not particularly limited, but may be hydrocarbon groups or derivatives thereof. A derivative of a hydrocarbon group means a group having one or more N, O, S, Si, amide, sulfonyl, siloxane, carbonyl, carbonyloxy, etc., at the terminal or molecular chain of a hydrocarbon group. When simply referred to as "organic group," it means a monovalent organic group. Furthermore, "divalent organic group" means a divalent group containing carbon. Examples of such divalent organic groups include divalent groups obtained by removing one more hydrogen atom from an organic group. Similarly, trivalent or higher organic groups mean groups obtained by removing a predetermined number of hydrogen atoms from an organic group.

[0008] As used herein, "hydrocarbon group" means a group containing carbon and hydrogen, obtained by removing a hydrogen atom from a hydrocarbon. Such hydrocarbon groups are not particularly limited, but include C 1-30Examples of hydrocarbon groups include aliphatic hydrocarbon groups and aromatic hydrocarbon groups. The above-mentioned "aliphatic hydrocarbon group" may be linear, branched, or cyclic, and may be saturated or unsaturated. The hydrocarbon group may also contain one or more ring structures. The hydrocarbon group may be substituted with one or more substituents.

[0009] In the use herein, the substituents of the "hydrocarbon group" are not particularly limited, but may be, for example, a halogen atom, or a halogen atom, or C 1-6 Alkyl alkyl group, C 2-6 Alkenyl group, C 2-6 Alkynyl group, C 3-10 Cycloalkyl groups, C 3-10 Unsaturated cycloalkyl group, 5-10 membered heterocyclyl group, 5-10 membered unsaturated heterocyclyl group, C 6-10 Examples include one or more groups selected from aryl groups and heteroaryl groups with 5 to 10 members.

[0010] As used herein, "hydrolyzable group" means a group that can undergo hydrolysis, that is, a group that can be removed from the main skeleton of a compound by hydrolysis. Examples of hydrolyzable groups include -OR h , -OCOR h , -ON=CR h 2. -NR h 2, -NHR h , or -NCO (wherein R in these formulas) h Examples include -OR (where - represents a substituted or unsubstituted C1-C4 alkyl group), and preferably -OR h (That is, an alkoxy group). h Examples include unsubstituted alkyl groups such as methyl, ethyl, propyl, isopropyl, n-butyl, and isobutyl groups; and substituted alkyl groups such as chloromethyl groups. Among these, alkyl groups, particularly unsubstituted alkyl groups, are preferred, and methyl or ethyl groups are more preferred.

[0011] The laminate of this disclosure comprises a substrate and a water-repellent layer located on the substrate. The nitrogen concentration on the surface of the above water-repellent layer is 0.01 atomic percent or more and 10 atomic percent or less. The fluorine concentration on the surface of the above water-repellent layer is less than 5 atomic percent. It is a laminated structure.

[0012] [Base material] The types of substrates included in the laminate of this disclosure are not particularly limited, but may consist of, for example, glass, resin (natural or synthetic resin, such as common plastic materials), metal, ceramics, semiconductors (silicon, germanium, etc.), fibers (textiles, nonwovens, etc.), fur, leather, wood, ceramics, stone, building materials, sanitary products, or any other suitable material.

[0013] 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, Ta3O5, Nb2O5, HfO2, Si3N4, 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.

[0014] The shape of the substrate is not particularly limited and may be, for example, a plate, a film, or other form. Furthermore, the surface area of ​​the substrate on which the water-repellent layer should be formed may 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.

[0015] In one embodiment, the substrate may consist of a material that originally has hydroxyl groups, at least on its surface. Examples of such materials include glass, 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 has insufficient hydroxyl groups, such as resins, or if it does not originally have 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.

[0016] In another embodiment, 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.

[0017] In a preferred embodiment, the substrate is glass. Such glass is not particularly limited, but examples include sapphire glass, soda-lime glass, alkali aluminosilicate glass, borosilicate glass, alkali-free glass, crystal glass, quartz glass, crystallized glass, chemically strengthened soda-lime glass, chemically strengthened alkali aluminosilicate glass, chemically bonded borosilicate glass, and the like.

[0018] The thickness of the substrate is not particularly limited, but is, for example, 5 μm or more, preferably 10 μm or more, and more preferably 20 μm or more. Also, the thickness of the substrate is, for example, 20 mm or less, preferably 10 mm or less, and more preferably 8 mm or less.

[0019] [Water-repellent layer] The water-repellent layer included in the laminate of this disclosure is located on the substrate. In this disclosure, "on the substrate" does not necessarily refer only to a configuration in which the water-repellent layer is in direct contact with the substrate, but may also refer to a configuration in which, for example, an intermediate layer exists between the substrate and the water-repellent layer. In a preferred embodiment, the water-repellent layer is located on the surface of the laminate.

[0020] The water-repellent layer included in the laminate of this disclosure can be formed by applying a surface treatment agent to the substrate or intermediate layer.

[0021] The water-repellent layer included in the laminate of this disclosure has a nitrogen concentration on its surface of 0.01 atomic percent or more and 10 atomic percent or less, and a fluorine concentration of less than 5 atomic percent.

[0022] In one embodiment, the nitrogen concentration on the surface of the water-repellent layer is 0.01 atomic percent or more and 10 atomic percent or less.

[0023] In one embodiment, the fluorine concentration on the surface of the water-repellent layer is less than 5 atomic percent. In a more preferred embodiment, the fluorine concentration on the surface of the water-repellent layer is less than 1 atomic percent. In an even more preferred embodiment, the fluorine concentration on the surface of the water-repellent layer is less than 0.1 atomic percent.

[0024] In a preferred embodiment, the silicon concentration on the surface of the water-repellent layer is 0.1 atomic percent or more and 50 atomic percent or less.

[0025] In a more preferred embodiment, the silicon concentration on the surface of the water-repellent layer is 15 atomic percent or more and 25 atomic percent or less.

[0026] The concentrations of each element on the surface of the water-repellent layer described above can be determined by surface analysis. Surface analysis methods include X-ray photoelectron spectroscopy (XPS) and time-of-flight secondary ion mass spectrometry. Typically, XPS analysis is used.

[0027] For XPS analysis to measure the elemental concentrations on the surface of the water-repellent layer, the ULVAC-PHI PHI5000VersaProbeII can be used. The XPS analysis conditions are as follows: a monochromatic AlKα X-ray source at 25W, a photoelectron detection area of ​​1400μm × 300μm, a photoelectron detection angle in the range of 20 to 90 degrees (e.g., 20°, 45°, 90°), and a pass energy of 23.5eV. Ar ions can be used as sputter ions. Using the above apparatus and measurement conditions, the nitrogen, fluorine, and silicon concentrations on the surface of the water-repellent layer can be determined based on the spectra of N1s, F1s, and Si2p orbitals.

[0028] The specific measurement methods and conditions may be as follows. The surface of the water-repellent layer applied to the substrate can be measured using an X-ray photoelectron spectroscopy (XPS) analyzer (ULVAC-PHI PHI5000VersaProbeII). The measurement conditions for XPS analysis are as follows, for example: X-ray source: Monochromatic AlKα rays (25W) Photoelectron detection area: 1400 μm × 300 μm Photoelectron detection angle: 45 degrees Pass energy: 23.5 eV Measured elements: Carbon (C1s) 278-298 eV, Nitrogen (N1s) 390-410 eV, Oxygen (O1s) 523-543 eV, Fluorine (F1s) 680-698 eV, Silicon (Si2p) 94-114 eV

[0029] From the peak shapes and intensities obtained in each region, the atomic ratios corresponding to each element can be calculated.

[0030] By adjusting the photoelectron detection angle in the XPS analysis described above, the detection depth can be adjusted as needed. For example, by setting a shallow angle close to 20 degrees, the detection depth can be set to about 3 nm, while by setting a deep angle close to 90 degrees, the detection depth can be set to about 10-something nm.

[0031] Furthermore, in compositional analysis using XPS analysis, if silicon originating from the substrate is detected, the amount of Si in the substrate can be calculated from the detected amount of specific atoms in the substrate—for example, if the substrate is glass, trace amounts of metal atoms (e.g., Al, Na, K, B, Ca, Mg, Sn, etc.)—and subtracted from the measurement result. This allows for the differentiation of silicon concentration originating from the water-repellent layer from silicon concentration originating from the substrate.

[0032] In one embodiment, when measuring the silicon concentration on the surface of the water-repellent layer, silicon originating from the intermediate layer, such as the silicon dioxide layer, can be detected. In another embodiment, when measuring the silicon concentration on the surface of the water-repellent layer, silicon originating from the intermediate layer, such as the silicon dioxide layer, cannot be detected.

[0033] The nitrogen concentration on the surface of the water-repellent layer is defined as the atomic ratio of the total amounts of carbon, nitrogen, oxygen, fluorine, and silicon.

[0034] The fluorine concentration on the surface of the water-repellent layer is defined as the atomic ratio of the total amounts of carbon, nitrogen, oxygen, fluorine, and silicon.

[0035] The silicon concentration on the surface of the water-repellent layer is defined as the atomic ratio of the total amounts of carbon, nitrogen, oxygen, fluorine, and silicon.

[0036] The nitrogen, fluorine, and silicon concentrations mentioned above can be measured at three different points on the surface of the water-repellent layer, and the average value can be used.

Furthermore, the water-repellent layer contained in the laminate of this disclosure may possess both high abrasion resistance and fingerprint-wiping properties.

[0544] When using the dry coating method, the above surface treatment agent may be applied to the dry coating method as is, or it may be diluted with the above solvent before being applied to the dry coating method.

[0545] The formation of the water-repellent layer is preferably carried out such that the surface treatment agent is present in the layer together with a catalyst for hydrolysis and dehydration condensation. For convenience, in the case of the wet coating method, the catalyst may be added to the diluted solution of the surface treatment agent immediately after diluting it with a solvent and applying it to the substrate surface. In the case of the dry coating method, the surface treatment agent with the catalyst added may be directly vapor-deposited (usually by vacuum deposition), or a pellet-like material impregnated with the surface treatment agent with the catalyst added may be used for vapor deposition (usually by vacuum deposition).

[0546] Any suitable acid or base, transition metals (e.g., Ti, Ni, Sn, Zr, Al, B, etc.), sulfur-containing compounds having lone pairs of electrons in their molecular structure, or nitrogen-containing compounds (e.g., sulfoxide compounds, aliphatic amine compounds, aromatic amine compounds, phosphate amide compounds, amide compounds, urea compounds, etc.) can be used as catalysts. Examples of acid catalysts include acetic acid, formic acid, trifluoroacetic acid, hydrochloric acid, nitric acid, sulfuric acid, phosphoric acid, sulfonic acid, methanesulfonic acid, and p-toluenesulfonic acid. Examples of base catalysts include ammonia, sodium hydroxide, potassium hydroxide, and organic amines such as triethylamine and diethylamine. Examples of transition metals, aliphatic amine compounds, and aromatic amine compounds are the same as those mentioned above.

[0547] The articles of this disclosure are described below.

[0548] The articles of this disclosure include the laminate described above.

[0549] In one embodiment, the article of the present disclosure may include an intermediate layer containing silicon dioxide between the glass and the water-repellent layer. By providing such an intermediate layer, the adhesion between the glass and the water-repellent layer is improved, and the durability is improved.

[0550] In a preferred embodiment, the intermediate layer may contain alkali metal atoms in addition to silicon dioxide.

[0551] Examples of the alkali metal atoms mentioned above include lithium, sodium, and potassium. The alkali metal atom is preferably sodium.

[0552] 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.

[0553] The alkali metal atom concentration in the intermediate layer can be measured using various surface analysis devices, such as TOF-SIMS, XPS, and XRF.

[0554] The proportion of alkali metal atoms in the total atoms of the intermediate layer can be obtained by XPS depth profiling using ion sputtering. This is done by repeatedly alternating between XPS measurement and surface etching using an ion gun built into the XPS instrument.

[0555] In the intermediate layer, the average concentration of alkali metals in the region with a depth of 1 nm or less from the surface in contact with the water-repellent layer is determined by obtaining a depth profile of alkali metal atom concentrations using TOF-SIMS (time-of-flight secondary ion mass spectrometry) depth profiling by ion sputtering, and then calculating the average value of alkali metal atom concentrations in that profile. TOF-SIMS depth profiling by ion sputtering is performed by alternately repeating TOF-SIMS measurements and surface etching by ion sputtering using an ion gun built into the TOF-SIMS instrument.

[0556] The articles of this disclosure may be optical components, but are not limited to these. 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 for optical discs such as Blu-ray (registered trademark) discs, DVD discs, CD-Rs, and MOs; optical fibers; and display surfaces for watches.

[0557] Furthermore, the articles of this disclosure may be medical devices or medical materials. Also, articles having a water-repellent layer obtained by this disclosure may be automotive interior and exterior components. Examples of exterior components include: windows, light covers, and exterior camera covers. Examples of interior components include: instrument panel covers, navigation system touch panels, and decorative interior components.

[0558] The silicon dioxide intermediate layer described above can be formed by applying a silicon dioxide precursor to the surface of the substrate. If the intermediate layer contains alkali metal atoms, it can be formed by applying a composition containing a silicon dioxide precursor and an alkali metal source to the surface of the substrate.

[0559] Examples of silicon oxide precursors include silicic acid, partial condensates of silicic acid, alkali metal silicates, silane compounds having a hydrolyzable group bonded to a silicon atom, and partial hydrolyzable condensates of the silane compounds. Silicic acid and its partial condensates can be dehydrated and condensed to produce silicon oxide, while alkali metal silicates can be converted to silicic acid or its partial condensates using an acid or cation exchange resin, and the resulting silicic acid or partial condensates can be dehydrated and condensed to produce silicon oxide. Examples of hydrolyzable groups in silane compounds having a hydrolyzable group bonded to a silicon atom include alkoxy groups and chlorine atoms. The hydrolyzable group in the silane compound can be hydrolyzed to a hydroxyl group, and the resulting silanol compound can be dehydrated and condensed to produce silicon oxide. Examples of silane compounds having a hydrolyzable group bonded to a silicon atom include alkoxysilanes such as tetraalkoxysilanes and alkyltrialkoxysilanes, and tetrachlorosilanes.

[0560] Examples of alkali metal sources include alkali metal hydroxides and water-soluble alkali metal salts. Examples of water-soluble alkali metal salts include alkali metal carbonates, alkali metal bicarbonates, alkali metal hydrochlorides, and alkali metal nitrates. Alkali metal hydroxides and alkali metal carbonates are preferred as alkali metal sources.

[0561] Furthermore, alkali metal silicates can be used as silicon oxide precursors and alkali metal sources. Alkali metal silicates can be converted to silicon oxide via silicic acid, but a small amount of alkali metal may remain in the silicon oxide produced during this process. Therefore, by adjusting the amount of residual alkali metal atoms, silicon oxide containing a predetermined amount of alkali metal atoms can be obtained.

[0562] The water-repellent layer contained in the article of this disclosure may have high abrasion resistance as described above. In addition to high abrasion resistance, the water-repellent 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.), surface slipperiness (or lubricity, e.g., ease of wiping away dirt such as fingerprints and excellent tactile feel to the fingers), and chemical resistance, and can be suitably used as a functional thin film.

[0563] Accordingly, this disclosure also relates to optical materials having the above-mentioned water-repellent layer as the outermost layer.

[0564] 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.

[0565] The articles of this disclosure may be optical components, but are not limited to these. 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 for optical discs such as Blu-ray (registered trademark) discs, DVD discs, CD-Rs, and MOs; optical fibers; and display surfaces for watches.

[0566] Furthermore, the articles of this disclosure may be medical devices or medical materials. Also, articles having layers obtained by this disclosure may be automotive interior and exterior components. Examples of exterior components include: windows, light covers, and exterior camera covers. Examples of interior components include: instrument panel covers, navigation system touch panels, and decorative interior components.

[0567] The thickness of the above layer is not particularly limited. In the case of optical components, the thickness of the above layer may be in the range of, for example, 1 to 50 nm, preferably 1 to 30 nm, and more preferably 1 to 15 nm, from the viewpoint of optical performance, wear resistance, and antifouling properties.

[0568] For X-ray photoelectron spectroscopy (XPS) analysis to measure the atomic composition and constituent atom ratios of the water-repellent layer, an XPS system, specifically the ULVAC-PHI PHI5000VersaProbeII, can be used. XPS analysis conditions include a 25W monochromatic AlKα X-ray source, a 1400μm × 300μm photoelectron detection area, a photoelectron detection angle in the range of 20 to 90 degrees (e.g., 20, 45, 90 degrees), and a pass energy of 23.5eV. For sputtering, gas cluster ion beams or Ar ions can be used. Using the above apparatus and measurement conditions, the peak areas of F1s, C1s, O1s, and Si2p can be observed, and the atomic ratios of fluorine, carbon, oxygen, and silicon can be calculated to determine the composition of the water-repellent layer and the intermediate layer.

[0569] Furthermore, depth analysis can also be performed. For XPS analysis, the measurement conditions include using a monochromatic AlKα X-ray source at 25W, a photoelectron detection area of ​​1400 μm × 300 μm, a photoelectron detection angle in the range of 20 to 90 degrees (e.g., 20 degrees, 45 degrees, 90 degrees), and a pass energy of 23.5 eV. Sputter ions such as Ar ions, gas cluster ions, and C60 ions can be used. Sputtering can also be used to etch 1 to 100 nm and obtain the composition of the coating film at each etching depth.

[0570] By adjusting the photoelectron detection angle in the XPS analysis described above, the detection depth can be adjusted as needed. For example, by setting a shallow angle close to 20 degrees, the detection depth can be set to about 3 nm, while by setting a deep angle close to 90 degrees, the detection depth can be set to about 10-something nm.

[0571] The silicon dioxide intermediate layer described above can be formed by applying a silicon dioxide precursor to the surface of the substrate. If the intermediate layer contains an alkali metal, it can be formed by applying a composition containing a silicon dioxide precursor and an alkali metal source to the surface of the substrate.

[0572] Examples of silicon oxide precursors include silicic acid, partial condensates of silicic acid, alkali metal silicates, silane compounds having a hydrolyzable group bonded to a silicon atom, and partial hydrolyzable condensates of the silane compounds. Silicic acid and its partial condensates can be dehydrated and condensed to produce silicon oxide, while alkali metal silicates can be converted to silicic acid or its partial condensates using an acid or cation exchange resin, and the resulting silicic acid or partial condensates can be dehydrated and condensed to produce silicon oxide. Examples of hydrolyzable groups in silane compounds having a hydrolyzable group bonded to a silicon atom include alkoxy groups and chlorine atoms. The hydrolyzable group in the silane compound can be hydrolyzed to a hydroxyl group, and the resulting silanol compound can be dehydrated and condensed to produce silicon oxide. Examples of silane compounds having a hydrolyzable group bonded to a silicon atom include alkoxysilanes such as tetraalkoxysilanes and alkyltrialkoxysilanes, and tetrachlorosilanes.

[0573] Examples of alkali metal sources include alkali metal hydroxides and water-soluble alkali metal salts. Examples of water-soluble alkali metal salts include alkali metal carbonates, alkali metal bicarbonates, alkali metal hydrochlorides, and alkali metal nitrates. Alkali metal hydroxides and alkali metal carbonates are preferred as alkali metal sources.

[0574] Furthermore, alkali metal silicates can be used as silicon oxide precursors and alkali metal sources. Alkali metal silicates can be converted to silicon oxide via silicic acid, but a small amount of alkali metal may remain in the silicon oxide produced during this process. Therefore, by adjusting the amount of residual alkali metal, silicon oxide containing a predetermined amount of alkali metal atoms can be obtained.

[0575] The thickness of the above-mentioned intermediate layer is not particularly limited, but is, for example, in the range of 1 to 50 nm, preferably 1 to 30 nm, more preferably 2 to 15 nm, and even more preferably 3 to 10 nm.

[0576] The compounds, compositions, and articles of this disclosure have been described in detail above. However, the compounds, compositions, and articles of this disclosure are not limited to those exemplified above.

Specifically, 0.1 g of the surface treatment agent was filled into a molybdenum boat in the vacuum deposition apparatus, and the inside of the vacuum deposition apparatus was evacuated to a pressure of 3.0×10 -3 Pa or less. Then, using Formed Body 1, it was deposited by the electron beam evaporation method to form a silicon dioxide film containing Na with a thickness of 5 nm, and subsequently, the surface treatment layer (i.e., water-repellent layer) was formed by heating the boat by the resistance heating method. Thereafter, a heat treatment was performed in an oven at 150°C for 2 hours to obtain the surface treatment layer.

[0666] <Rating> [Measurement of water contact angle after film formation] After thoroughly wiping the surface of the substrate with the surface treatment layer prepared using the method described above with Kimwipes S-200 (product name, manufactured by Nippon Paper Crecia) impregnated with ethanol, the static contact angle of water was measured.

[0667] (Contact angle measurement) Contact angle measurements were performed at 25°C using a fully automatic contact angle meter, DropMaster700 (manufactured by Kyowa Interface Science Co., Ltd.). Specifically, the substrate with the surface treatment layer to be measured was placed horizontally, 2 μL of water was dropped onto its surface from a microsyringe, and a still image was captured with a video microscope 1 second after dropping to measure the static contact angle. The static contact angle was measured at five different points on the surface treatment layer of the substrate, and the average value was used.
