Abstract

The invention belongs to the technical field of nanometer hybrid composite materials and discloses an anti-reflection coating constructed based on cage type silsesquioxane and the preparing method and application thereof. The preparing method of the anti-reflection coating comprises the steps that a base reaction layer is constructed with 10-methacrylonitrile acyloxy propyl group cage type silsesquioxane and 8-aminophenyl group cage type silsesquioxane and then is precured, a surface layer is constructed with fluorinated acrylate prepolymer and 8-methacrylonitrile acyloxy propyl group cage type silsesquioxane, the two layers are co-cured under a certain condition, and stress is generated by means of the difference in reaction volume shrinkage of the two layers. The prepared anti-reflection coating is of a nanometer island structure, and the anti-reflection performance is improved remarkably. The anti-reflection coating can be widely applied to optical devices which require high anti-reflection performance.

Description

technical field [0001] The invention belongs to the technical field of nano-hybrid composite materials, and in particular relates to an anti-reflection coating based on cage-type silsesquioxane and its preparation method and application. Background technique [0002] In the world we live in, sunshine is everywhere around us. Light is a natural phenomenon that people encounter at any time in their daily life, and it brings countless benefits to people. However, in some cases, some unnecessary light reflections will occur when light passes through the interface between two media, and the existence of these light reflections also brings some problems that need to be overcome. For example, when the display screen of the display is illuminated by the light of the surrounding environment, such as sunlight or external light, there will be mirror reflection and reflection phenomenon, and the screen that should be displayed on the display screen will overlap with the light and landsc...
