Embodiment 1
[0013] The process of the preparation method of the transparent antifouling film involved in this embodiment is as follows: under normal temperature and pressure conditions, disperse 0.05 g of hydrotalcite nanosheets in 9.8 g of distilled water for 30 minutes to obtain an aqueous solution of hydrotalcite, and then 0.2 g of polyethylene Alcohol was added to the hydrotalcite aqueous solution and heated to 80°C until the polyvinyl alcohol dissolved to form a mixed solution. The mixed solution was allowed to stand for natural cooling and then ultrasonically dispersed for 30 minutes. Then, a volume of 200 μL and a concentration of 2×10 -3 mol / L phenamide ethanol solution was dispersed by ultrasound for 30 minutes to obtain an antifouling solution. The antifouling solution was coated on the quartz surface by the spin coating method. After drying for 24 hours at normal temperature and pressure, the antifouling solution on the quartz surface formed a transparent antifouling solution. ...
Embodiment 2
[0017] The process of the preparation method of the transparent antifouling film involved in this example is as follows: under normal temperature and pressure conditions, disperse 0.01 g of hydrotalcite nanosheets in 9.7 g of distilled water for 30 minutes to obtain a hydrotalcite aqueous solution, and then 0.3 g of polyethylene Alcohol was added to the hydrotalcite aqueous solution and heated to 90°C until the polyvinyl alcohol dissolved to form a mixed solution. The mixed solution was allowed to stand for natural cooling and then ultrasonically dispersed for 30 minutes. Then, a volume of 200 μL and a concentration of 1×10 -3 mol / L phenamide ethanol solution was dispersed by ultrasound for 30 minutes to obtain an antifouling solution. The antifouling solution was coated on the quartz surface by a coating method. After drying for 24 hours at normal temperature and pressure, the antifouling solution on the quartz surface formed a transparent antifouling solution. film to realiz...
