[0453] Example
[0454] The present invention will be described in more detail below using examples, but the present invention is not limited to these examples.
[0455] [Synthesis of Compound 1]
[0456]
[0457] Compound 1a was synthesized following the synthetic method for precursor (4a-2) described in International Publication No. 2013 / 121984. The average number of repeating units n was 13.
[0458] Add 4-(aminomethyl)-1-tert-butoxycarbonylpiperidine (0.071 g, 1.33 mmol), 4-(N,N-dimethylamino)pyridine (0.081 g, 0.66 mmol), ASAHIKLIN AC-2000 (manufactured by AGC Corporation, 0.838 g, 0.5 mL, hereinafter referred to as "AC-2000"), 1,4-dioxane (0.517 g, 0.5 mL), and compound 1a (number average molecular weight: approximately 4500, 1.0 g, 0.22 mmol) to a 30 mL flask. Stir at 25 °C for 3 days using a magnetic stirrer. Then, add methanol (1 mL) to the resulting solution, stir, and allow to stand. Repeat the process three times to remove the supernatant using a pipette. Add AC-2000 (5 mL) to the resulting solution and remove the supernatant by vacuum distillation. The crude product was purified by column chromatography to obtain compound 1b (0.81 g).
[0459]
[0460] The obtained compound 1b was dissolved in AC-2000 (6 mL) and cooled to 0 °C. Then, a 4N hydrogen chloride / ethyl acetate solution (2 mL) was added, and the mixture was stirred for 4 hours. After removing the solvent by vacuum distillation, AC-2000 (10 mL) and a 5% (w / w) sodium carbonate aqueous solution (2 mL) were added. After stirring, the lower layer was dried using sodium sulfate. The solvent was removed by vacuum distillation, thus giving compound 1 (0.54 g).
[0461] [Synthesis of Compound 2]
[0462]
[0463] In a 50 mL round-bottom flask, 1,3-diamino-2-propanol (0.065 g, 0.72 mmol), AC-2000 (9 mL), 1,4-dioxane (5.5 mL), and compound 1a (number average molecular weight: approximately 4500, 1.0 g, 0.22 mmol) were added. The mixture was stirred at 25 °C for 6 hours using a magnetic stirrer. After removing the solvent by vacuum distillation, the solution was dissolved in ASAHIKLIN AC-6000 (manufactured by AGC Corporation, hereinafter referred to as "AC-6000"), transferred to a separatory funnel, and the washing process with methanol was repeated three times. After removing AC-6000 by vacuum distillation, the crude product of compound 2 (1.13 g) was obtained.
[0464] The crude product of compound 2 was dissolved in an AC-2000 (5 mL) container, and triethylamine (0.1 mL, 0.72 mmol), 1,4-dioxane (1 mL), and di-tert-butyl dicarbonate (0.12 mL, 0.54 mmol) were added. The mixture was then stirred at 25 °C for 2 weeks using a magnetic stirrer. After removing the solvent by vacuum distillation, the crude product was purified by column chromatography to obtain compound 2a (0.48 g).
[0465]
[0466] The obtained compound 2a (0.2 g) was dissolved in AC-2000 (1.5 mL) and cooled to 0 °C. Then, a 4N hydrogen chloride / ethyl acetate solution (1.1 mL) was added, and the mixture was stirred for 1 day. Next, the solvent was removed by vacuum distillation. The crude product was then added to AC-2000 (10 mL) and a 5% (w / w) sodium bicarbonate aqueous solution (2 mL), stirred, and allowed to stand. The lower layer was separated and dried using sodium sulfate. After filtration, the solvent was removed by vacuum distillation to obtain compound 2 (0.20 g).
[0467] Next, surface treatment agent 1 and surface treatment agent 2 were prepared using compound 1 and compound 2.
[0468] [Preparation of Surface Treatment Agent 1 and Surface Treatment Agent 2]
[0469] A mixed solution of AC-2000 and ethanol (ethanol concentration: 3% by mass) was added relative to compound 1 (0.05 g) to bring the content of compound 1 to 0.1% by mass. The resulting solution was used as surface treatment agent 1. Surface treatment agent 2 was prepared from compound 2 using the same method.
[0470] [Item crafting]
[0471] (Examples 1 to 4, 7 to 9, 11, 13, 15, 16, 20 to 27)
[0472] As the substrate, a PMMA substrate (acrylic sheet (MR sheet) manufactured by Acrysunday Co., Ltd., with a surface hardness (pencil hardness) of 6H and a thickness of 10cm × 10cm × 3mm) that has undergone hard coating was used. The substrate was immersed in 200mL of an aqueous solution containing Brønsted acid as described in Tables 1-5, and then treated with ultrasound for 10 minutes. The substrate was then removed and dried in air. The substrate was then immersed in 200mL of an aqueous solution containing Lewis acids as described in Tables 1-5 at the concentrations described in Tables 1-5, and then treated with ultrasound for 10 minutes. The substrate was then removed and dried in air. Using a spin coater (product name "Opticoat MS-B200", manufactured by MIKASA Co., Ltd.), 2mL of a surface treatment agent containing the specific compounds described in Tables 1-5 was placed on the substrate and rotated at 500rpm for 1 minute. The substrate was then fired in an infrared furnace at the temperatures and times described in Tables 1-5 to obtain an article with a surface layer.
[0473] (Example 5)
[0474] Articles with a surface layer were obtained using the same method as in Example 1, without pretreatment with solutions containing Brønsted acid and Lewis acid.
[0475] (Examples 6, 10, 12, 14, 17)
[0476] Without pretreatment with solutions containing Brønsted acid and Lewis acid, the article with a surface layer was obtained by calcination at the temperatures and times recorded in Tables 1 to 5, except that the same method as in Example 1 was used.
[0477] (Example 18)
[0478] Instead of using a solution containing Brønsted acid, a solution containing Lewis acid was used for pretreatment, and otherwise an article with a surface layer was obtained by the same method as in Example 1.
[0479] (Example 19)
[0480] Instead of using a solution containing Lewis acid, a solution containing Brønsted acid was used for pretreatment, and otherwise an article with a surface layer was obtained by the same method as in Example 1.
[0481] The initial water contact angle of the obtained items was measured to evaluate abrasion resistance and warpage.
[0482] In addition, the mass of metal per unit area relative to the surface of the substrate was measured, and the result in Example 1 was 1.39 μg / cm³. 2 In Example 2, it was 1.44 μg / cm³. 2In Example 3, it was 0.069 μg / cm³. 2 In Example 4, it was 69.5 μg / cm³. 2 In the article, the molar ratio of the metal to the (poly)oxyfluoroalkyl chain is 1250 mol% in Example 1.
[0483] <Initial water contact angle>
[0484] Approximately 2 μL of pure water was added to the surface of the article where the surface layer was formed (hereinafter referred to as the "surface layer forming surface"). The water contact angle was measured using a contact angle measuring device (product name "DM-500", manufactured by Kyowa Interface Science Co., Ltd.). Measurements were taken at five different points on the surface layer forming surface, and the average value was calculated as the initial water contact angle. The contact angle was calculated using the 2θ method. It should be noted that an ionizer and a forced-air treatment were performed for each measurement before determining the water contact angle.
[0485] <Abrasion Resistance>
[0486] For the surface layer forming of the item, use a pressure head equipped with KANAKIN No. 3 (bottom area: 100mm²). 2 The wear test was conducted using a 3-stage surface wear testing machine (product name "PA-300A", manufactured by Daiei Scientific Instruments Co., Ltd.) under the following conditions: 24℃, 40% RH atmosphere, 1000g load, 60rpm rotation speed, and 40mm stroke length. After a specified number of friction cycles, the water contact angle was measured. The method for measuring the water contact angle is the same as that for measuring the initial water contact angle. It should be noted that "-" in the table indicates that the water contact angle cannot be measured.
[0487] <Warp>
[0488] The resulting article was placed on a flat and level platform. The height A2 of the central portion of the article was measured using vernier calipers. Similarly, the height A1 of the central portion was measured for articles before firing during the manufacturing process. Warpage was evaluated based on the value (ΔH) obtained by subtracting A1 from A2. It can be said that the smaller the ΔH, the more suppressed the warpage. It should be noted that the unit of ΔH representing warpage in the table is mm. In the table, "-" in the component column indicates that the component was not added. "-" in the number of friction cycles column indicates that it was not performed.
