Abstract

The invention belongs to the technical field of nano-grade material preparation, and especially relates to a preparation method of a wear-resistant antireflective coating comprising mesopores, and a wear-resistant antireflective coating comprising mesopores prepared with the method. According to the invention, a cheap and easy-to-obtain common glass sheet is adopted as a substrate; tetraethyl orthosilicate, ammonia water, anhydrous ethanol, cetyl trimethyl ammonium bromide and water are adopted as raw materials; with a simple solution deposition method, a sealed reaction is carried out for 16-48h in a baking oven with a temperature of 40-80 DEG C; and a templating agent CTAB is removed with a calcination method, such that the wear-resistant antireflective coating comprising mesopores is obtained. The glass sheet coated with the coating can endure scratch test with a 6H pencil. Light transmittance of the glass sheet coated with the coating can be improved from 91.3% to 99.4%. The wear-resistant antireflective coating preparation method is simple, and cost is low. The obtained wear-resistant antireflective coating has the advantages of excellent performances, good durability, wide application range, and the like.

Description

technical field [0001] The invention belongs to the technical field of nanometer material preparation, and in particular relates to a preparation method of a wear-resistant anti-reflection coating containing mesoporous pores, and a wear-resistant anti-reflective coating containing mesoporous pores obtained by the method. Background technique [0002] AR coatings are widely used in optical devices such as solar cells to reduce surface reflections. Since the anti-reflection coating is between the air and the substrate, the refractive index of the coating must be between the air and the substrate to produce an anti-reflection effect. An ideal single-layer anti-reflection coating needs to meet the following conditions: the optical thickness of the coating is λ / 4, where λ is the optical wavelength; n c =(n a ×n s ) 0.5 , where n c , n a and n s Respectively represent the refractive index of the coating, air and substrate [Yoldas, B.E.Appl.Opt.1980,19,1425.]. If the refrac...
