Description

Composition, surface treatment agent, article, and method for manufacturing article

[0001] This disclosure relates to compositions, surface treatment agents, articles, and methods for manufacturing articles.

[0002] In recent years, technologies that make optical articles less prone to fingerprints and easier to clean have become widespread in eyeglass lenses, wearable devices, touch panel displays, and other devices to improve their appearance and visibility. One specific method for applying these technologies to improve the appearance, visibility, and other performance aspects of these devices is to form a surface layer on the surface of the article using a surface treatment agent. The use of materials with such surface layers is expected to contribute to achieving Goal 12 of the United Nations' Sustainable Development Goals (SDGs), "Responsible Consumption and Production," as it leads to a longer product lifecycle and, consequently, a reduction in waste.

[0003] For example, Patent Document 1 describes a method for forming a surface layer on the surface of a substrate using a surface treatment agent containing a perfluoropolyether compound represented by the following formula.

In numerical ranges described in stages in this disclosure, the upper or lower limit of one numerical range may be replaced with the upper or lower limit of another numerical range described in stages. Also, in numerical ranges described in this disclosure, the upper or lower limit of that numerical range may be replaced with the values ​​shown in the examples. In this disclosure, each component may contain multiple types of the corresponding substance. If multiple types of the substance corresponding to each component are present in the composition, the content or amount of each component means the total content or amount of the multiple types of substances present in the composition, unless otherwise specified. In this disclosure, "surface layer" means a layer formed on the surface of a substrate using a surface treatment agent.

[0228] [Surface Treatment Agent] In one embodiment, the surface treatment agent of the present disclosure (hereinafter also referred to as "the surface treatment agent") comprises the composition of the present disclosure. The surface treatment agent may also be the composition of the present disclosure. Preferred embodiments of the surface treatment agent are the same as preferred embodiments of the composition of the present disclosure.

[0229] This surface treatment agent is suitable for applications requiring sweat resistance, such as forming a surface layer on components that make up the touch surfaces of touch panels, eyeglass lenses, and displays of wearable devices. Furthermore, due to its excellent sweat resistance, this surface treatment agent is also suitable for use on glass-coated casings of portable devices such as smartphones and tablet terminals. This surface treatment agent is also suitable for use as an anti-fouling or waterproof coating agent.

[0230] [Article] In one embodiment, the article of the present disclosure (hereinafter also referred to as "the Article") has a surface layer formed using the surface treatment agent on the surface of a substrate. Preferably, the Article has a substrate and the above-mentioned surface layer.

[0231] The surface layer may be formed on a part of the surface of the substrate or on the entire surface of the substrate. The surface layer may spread as a film on the surface of the substrate or may be scattered as dots. In the surface layer, the first compound is contained in a state in which hydrolysis of some or all of the reactive silyl groups has progressed and the dehydration condensation reaction of the silanol groups has progressed.

[0232] The thickness of the surface layer is preferably 1 to 100 nm, and more preferably 1 to 50 nm. If the thickness of the surface layer is 1 nm or more, the effect of the surface layer is easily obtained. If the thickness of the surface layer is 100 nm or less, the utilization efficiency is high. The thickness of the surface layer can be calculated from the vibration period of the interference pattern obtained by the X-ray reflectivity method using an X-ray diffractometer for thin film analysis (product name "ATX-G", manufactured by RIGAKU Corporation).

[0233] The surface layer may be provided directly on the surface of the substrate, or a base layer may be provided between the substrate and the surface layer. From the viewpoint of further improving the water repellency and abrasion resistance of the surface layer, it is preferable that the article includes a substrate, a base layer disposed on the substrate, and a surface layer formed using the surface treatment agent disposed on the base layer.

[0234] An example of this article will be described with reference to the drawings. Figure 1 is a schematic cross-sectional view showing a first article, which is an example of this article. The first article is an article 20 having a base material 12, a base layer 14, and a surface layer 22 in that order, wherein the base layer 14 contains an oxide containing silicon, and the surface layer 22 is a surface layer formed using this surface treatment agent.

[0235] The material and shape of the base material 12 may be appropriately selected according to the intended use of the article 20. The type of base material is not particularly limited; for example, a base material for which sweat resistance is required can be used. Examples of base materials include base materials that may be used in contact with human fingers; base materials that may be held by human fingers during operation; and base materials that may be placed on other articles (e.g., a stand). Examples of materials for the base material 12 include glass, resin, sapphire, metal, ceramic, stone, and composite materials thereof. Glass may be chemically strengthened. Examples of base materials 12 for which water-repellent and oil-repellent properties are particularly required include base materials for touch panels, base materials for displays, base materials that constitute the housing of electronic devices, and eyeglass lenses. The base materials for touch panels and display base materials are translucent. "Translucent" means that the normal incidence visible light transmittance in accordance with JIS R3106:1998 (ISO 9050:1990) is 25% or more. Glass or transparent resin is preferred as the material for the base material for touch panels.

[0236] The substrate 12 may have surface treatments such as corona discharge treatment, plasma treatment, or plasma graft polymerization treatment applied to the surface on which the underlayer 14 is provided. Surface treatment further improves the adhesion between the substrate 12 and the underlayer 14, and as a result, the abrasion resistance of the surface layer 22 is further improved. As for the surface treatment, corona discharge treatment or plasma treatment is preferred because it further improves the abrasion resistance of the surface layer 22.

[0237] The base layer 14 is a layer containing an oxide that includes at least silicon, and may also contain other elements. By including silanol groups on the surface of the base layer 14, the hydrolyzable silyl groups of the compound undergo dehydration condensation, forming Si-O-Si bonds between the base layer 14 and the surface layer 22, which has superior abrasion resistance.

[0238] The silicon dioxide content in the base layer 14 is preferably 65% ​​by mass or more, more preferably 80% by mass or more, even more preferably 85% by mass or more, and particularly preferably 90% by mass or more. If the silicon dioxide content is above the lower limit of the above range, sufficient Si-O-Si bonds are formed in the base layer 14, and the mechanical properties of the base layer 14 are sufficiently ensured. The silicon dioxide content is the remainder obtained by subtracting the total content of other elements (or the sum of the amounts converted to oxides in the case of oxides) from the mass of the base layer 14.

[0239] From the standpoint of excellent wear resistance of the surface layer 22, it is preferable that the oxide in the base layer 14 further contains one or more elements selected from alkali metal elements, alkaline earth metal elements, platinum group elements, boron, aluminum, phosphorus, titanium, zirconium, iron, nickel, chromium, molybdenum, and tungsten. The inclusion of these elements strengthens the bond between the base layer 14 and the compound, improving wear resistance.

[0240] To improve the adhesion of this surface treatment agent and to improve the water-repellent, oil-repellent, and abrasion-resistant properties of article 20, the base layer 14 is preferably a silicon oxide layer containing alkali metal atoms. In the silicon oxide layer, the average concentration of alkali metal atoms in the region at a depth of 0.1 to 0.3 nm from the surface in contact with the surface layer 22 is 2.0 × 10⁻¹⁶. 19 atoms / cm 3 The above is preferable. On the other hand, in order to ensure sufficient mechanical properties of the underlying layer, the average value of the alkali metal atom concentration should be 4.0 × 10 22 atoms / cm 3 The following is preferable:

[0241] The base layer may be a single layer or multiple layers. The base layer may have irregularities on its surface. The thickness of the base layer 14 is preferably 1 to 200 nm, and more preferably 2 to 20 nm. If the thickness of the base layer 14 is above the lower limit of the above range, the effect of improving adhesion by the base layer 14 is likely to be sufficiently obtained. If the thickness of the base layer 14 is below the upper limit of the above range, the abrasion resistance of the base layer 14 itself will be increased. Methods for measuring the thickness of the base layer 14 include cross-sectional observation of the base layer 14 using an electron microscope (SEM, TEM, etc.), and methods using an optical interferometer, spectroscopic ellipsometer, step meter, etc.

[0242] Specific examples of methods for forming the underlayer 14 include a method of depositing a vapor deposition material having the desired underlayer 14 composition onto the surface of the substrate 12. One example of a vapor deposition method is the vacuum vapor deposition method. The vacuum vapor deposition method involves evaporating the vapor deposition material in a vacuum chamber and depositing it onto the surface of the substrate 12. The temperature during vapor deposition (for example, the temperature of the boat in which the vapor deposition material is placed when using a vacuum vapor deposition apparatus) is preferably 100 to 3,000°C, and more preferably 500 to 3,000°C. The pressure during vapor deposition (for example, the absolute pressure in the chamber in which the vapor deposition material is placed when using a vacuum vapor deposition apparatus) is preferably 1 Pa or less, and more preferably 0.1 Pa or less. When forming the underlayer 14 using a vapor deposition material, one vapor deposition material may be used, or two or more vapor deposition materials containing different elements may be used. Examples of evaporation methods for the vapor deposition material include the resistance heating method, in which the vapor deposition material is melted and evaporated on a resistance heating boat made of high melting point metal, and the electron gun method, in which an electron beam is irradiated onto the vapor deposition material to directly heat the material, melt the surface, and evaporate it. As a method for evaporating the deposition material, the electron gun method is preferred because it allows for localized heating, enabling the evaporation of high-melting-point substances, and because the temperature is low in areas not exposed to the electron beam, eliminating the risk of reaction with the container or contamination by impurities. As the deposition material used in the electron gun method, molten granules or sintered bodies are preferred because they are less likely to scatter even if an airflow is generated.

[0243] Another example of this article is a second article. The second article is an article 20 having a substrate 10 with a base layer and a surface layer 22 in that order, wherein the substrate 10 with the base layer contains a silicon-containing oxide, and the surface layer 22 is a surface layer formed using this surface treatment agent.

[0244] In the second article, since the substrate 10 with the underlayer has the same composition as the underlayer 14 in the first article, the surface layer 22 has excellent abrasion resistance even when the surface layer 22 is directly formed on the substrate 10 with the underlayer. The material of the substrate 10 with the underlayer in the second article can be any material having the same composition as the underlayer 14, for example, a glass substrate. Details of the material of the substrate 10 with the underlayer are the same as those of the substrate 12 and the underlayer 14, so the explanation is omitted here. Also, the composition of the surface layer 22 is the same as that of the first article, so the explanation is omitted here.

[0245] Specific examples of this article include optical components (for example, optical components used as part of the products listed below), touch panels, anti-reflective films, anti-reflective glass, and SiO2. 2 Examples include processed glass, tempered glass, sapphire glass, quartz substrates, and mold metals. Products include: car navigation systems, mobile phones, digital cameras, digital video cameras, personal digital assistants (PDAs), portable audio players, car audio systems, gaming devices, eyeglass lenses, camera lenses, lens filters, sunglasses, medical equipment (endoscopes, etc.), photocopiers, personal computers (PCs), liquid crystal displays, organic EL displays, plasma displays, touch panel displays, protective films, anti-reflective films, anti-reflective glass, nanoimprint templates, molds, etc.

[0246] [Method for Manufacturing Articles] One method for manufacturing articles is to use this surface treatment agent to form a surface layer on the surface of a substrate, thereby manufacturing an article having a substrate and a surface layer. Methods for forming the surface layer include dry coating and wet coating.

[0247] This surface treatment agent can be used directly in dry coating methods and is suitable for forming a surface layer with excellent adhesion by dry coating. Examples of dry coating methods include vacuum deposition, CVD, and sputtering. Vacuum deposition is preferably used because it suppresses the decomposition of this surface treatment agent and because of the simplicity of the equipment. For vacuum deposition, a pellet-like material may be used in which the first compound and the second compound, etc., are supported using this composition on a porous metal body made of a metal material such as iron or steel. The pellet-like material on which the above compounds are supported can be manufactured by impregnating the porous metal body with this composition containing a liquid medium and drying to remove the liquid medium.

[0248] This surface treatment agent (coating solution) containing a liquid medium can be suitably used in wet coating methods. Examples of wet coating methods include spin coating, wipe coating, spray coating, squeegee coating, dip coating, die coating, inkjet coating, flow coating, roll coating, casting, Langmuir-Bludget coating, and gravure coating.

[0249] To improve the abrasion resistance of the surface layer, operations to promote the reaction between the first and second compounds contained in this composition and the substrate may be performed as needed. Such operations include heating, humidification, and light irradiation. For example, heating a substrate on which a surface layer has been formed in a humid atmosphere can promote reactions such as the hydrolysis of hydrolyzable groups, the reaction between hydroxyl groups on the surface of the substrate and silanol groups, and the formation of siloxane bonds through the condensation reaction of silanol groups. After the formation of the surface layer, compounds in the surface layer that are not chemically bonded to other compounds or the substrate may be removed as needed. Methods of removal include, for example, pouring a solvent onto the surface layer or wiping it with a cloth soaked in a solvent.

[0304] [Manufacturing of goods] 30 g of silicon oxide was placed as a deposition source in the copper hearth inside the vacuum deposition apparatus (ULVAC KIKO "VTR-350M"). A glass substrate (chemically strengthened glass) was placed inside the vacuum deposition apparatus, and the inside of the vacuum deposition apparatus was 5 × 10 -3The system was evacuated until the pressure was below Pa. The hearth was heated to approximately 2,000°C, and silicon oxide was vacuum-deposited onto the surface of the substrate to produce a substrate with a silicon oxide layer approximately 20 nm thick. Next, evaluation samples (articles) were manufactured using a vacuum deposition apparatus. First, 0.17 g of each surface treatment agent was filled into a molybdenum boat inside the vacuum deposition apparatus (ULVAC, product name: VTR350M), and the inside of the vacuum deposition apparatus was filled to 1 × 10⁻⁶ -3 The pressure was reduced to below Pa. Next, the boat containing the surface treatment agent was heated at a heating rate of 10°C / min or less. When the deposition rate measured by a quartz crystal film thickness gauge exceeded 1 nm / second, the shutter was opened to begin film formation on the substrate surface. When the film thickness reached approximately 50 nm, the shutter was closed to complete film formation on the substrate surface with the silicon oxide layer. The substrate on which the compound or composition was deposited was heat-treated at 140°C for 30 minutes and washed with ethanol to obtain an evaluation sample (article) in which the substrate, silicon oxide layer, and surface layer were laminated in that order.

[0305] [Evaluation] The following evaluations were conducted using the obtained items. The results of the evaluation tests are shown in Table 1.

[0306] <Water Contact Angle> Approximately 2 μL of distilled water was dropped onto the surface layer of each example's article, and the initial water contact angle (°) was measured using a contact angle measuring device (product name "DM-500", manufactured by Kyowa Interface Science Co., Ltd.). The arithmetic mean of the contact angle measurements taken at five locations on the surface layer was taken, and the resulting average value was defined as the water contact angle. The 2θ method was used to calculate the water contact angle. A larger initial water contact angle indicates better water repellency of the surface layer. From the obtained initial water contact angles, the initial water contact angle of the surface layer of each example's article was evaluated based on the evaluation criteria below. The evaluation results for each example are shown in the table below. (Evaluation Criteria) A: Initial water contact angle greater than 105° B: Initial water contact angle 105° or less

[0307] <Water-repellent properties (water drop angle)> For each example, an 8 μL water droplet was placed on the surface layer of the object, and using a drop angle meter (Kyowa Interface Science Co., Ltd., custom-made), it was tilted at a speed of 4° per minute. The tilt angle when the water droplet moved 1 mm was measured and defined as the water drop angle. From the obtained water drop angles, the water-repellent properties of the surface layer of each example object were evaluated based on the evaluation criteria below. The evaluation results for each example are shown in the table below. (Evaluation Criteria) A: Water drop angle is 2 degrees or less B: Water drop angle is greater than 2 degrees and 3 degrees or less C: Water drop angle is greater than 3 degrees and 5 degrees or less D: Water drop angle is greater than 5 degrees

[0308] <Abrasion Resistance> Using a reciprocating traverse testing machine (manufactured by KNT Co., Ltd., custom-made), a flannel cloth conforming to JIS L0803 was used, and a test of 1.25 N / cm² was performed on the surface layer of each example article. 2 After applying a load and performing 1000 reciprocating friction cycles at a speed of 100 cycles per minute, the water contact angle after the friction test was measured using the method described above. Wear resistance was evaluated based on the degree of decrease in the water contact angle due to the friction test. The evaluation results for each example are shown in the table below. Degree of decrease in water contact angle = (Initial water contact angle) - (Water contact angle after friction test) (Evaluation criteria) A: Degree of decrease in water contact angle is 8 degrees or less B: Degree of decrease in water contact angle is greater than 8 degrees and 10 degrees or less C: Degree of decrease in water contact angle is greater than 10 degrees and 15 degrees or less D: Degree of decrease in water contact angle is greater than 15 degrees

[0309]

[0310] As shown in Table 1, it was confirmed that a surface layer with excellent water-repellent properties and abrasion resistance can be formed by using a composition containing the first compound and the second compound (Examples 1-14).
