Problems solved by technology

[0004] However, the light transmittance of pure polyester film cannot meet the relevant technical requirements. Therefore, while improving the overall quality of polyester film, it is necessary to modify the surface of polyester film in order to obtain high light transmittance polyester film; Plating a suitable anti-reflection coating can reduce the reflection loss of its surface and increase its light transmittance, which is an effective means to improve the optical properties of polyester films; there are many types of anti-reflection coatings, and the hybrid material anti-reflection coating is relatively simple and eye-catching

Abstract

The invention relates to a preparation method of optical anti-reflection polyester films, and belongs to the field of surface modification of organic film materials. According to the invention, gamma-methacryloxy propyl trimethoxyl silane (KH570) and (meth)acrylate monomers are copolymerized through radical polymerization so as to obtain copolymers with different KH570 contents, and then the polymer is uniformly coated on the surface of a polyester film by using a spin coater. The preparation method disclosed by the invention is simple in operation; and the modified polyester film has light transmittance, and is applicable to the fields of display, optics and decoration and the like such as LED (light-emitting diodes), CRT (cathode ray tubes), PDP (plasma display panels), EL (electroluminescence) and the like.
