Preparation method of anti-radiation silicon oxide anti-reflection film

Abstract

The invention discloses a preparation method of an anti-radiation silicon oxide anti-reflection film. The preparation method is characterized by comprising the following steps: preparing an initial alkaline sol coating solution, adding an emulsifier polytetrafluoroethylene and nano-scale lead chloride powder, preparing a film on the surface of a substrate, carrying out supercritical drying to forma certain aerogel structure, carrying out a film heat treatment, preparing an initial alkaline sol coating solution; mixing and stirring tetraethoxysilane and anhydrous ethanol, slowly dropwise adding a mixed solution of anhydrous ethanol, deionized water and ammonia water after the solution is stirred uniformly, stirring and mixing uniformly, standing, aging, adding an emulsifier polytetrafluoroethylene emulsion, adding a certain amount of nano-powder lead chloride into the solution after the solution is aged and stabilized, sealing and stirring. The preparation method has the advantages that the operation is simple, the technological process is simplified, the prepared silicon oxide anti-reflection film can be accurately controlled to effectively protect space rays, the hardness is highand controllable, the silicon oxide anti-reflection film is suitable for space solar cells, and the practicability is high.

Description

Technical field [0001] The invention relates to the technical field of anti-reflection films, in particular to a method for preparing radiation-resistant silicon oxide anti-reflection films. Background technique [0002] Anti-reflection coating, also known as anti-reflection coating, its main function is to reduce or eliminate the reflected light of optical surfaces such as lenses, prisms, and plane mirrors, thereby increasing the amount of light transmitted by these components, reducing or eliminating stray light in the system, and anti-reflection coating The application in space is inevitably affected by the rays and high-energy particles in the space, resulting in weakening of its performance, which greatly affects the efficiency of space solar cells, and cannot protect space X-rays, gamma rays and neutrons to a certain extent: Therefore, there is a greater need for a method for preparing radiation-resistant silicon oxide anti-reflection film. Summary of the invention [0003]...
