Abstract

The invention belongs to the technical field of films, and particularly relates to a preparation method of a multifunctional light scattering film. The method comprises the steps of sequentially carrying out vacuum evaporation of 2, 7-dimethyl-3- (2, 4-dichlorophenyl) -paryzolo [1, 5-a] pyrimidine-6-formic acid, 6-chorine-2-methyl-3- (5-methoxy-2-hydroxylphenimethylamine) -4 (3H) -quinazolinone, 2-chlorine-5- (5-mercapto-4-isopropyl-4H-1, 2, 4-triazole-3-base) benzenesulfonamide, 4- acetoxy-3- Berberine methoxybenzoate on a glass plate, and preparing the multifunctional light scattering film,wherein the light transmittance of the film is 86%-91%, and the haze is 89%-93%; and the color of the multifunctional light scattering film is orange, yellow and green after irradiating white light, ultraviolet light with the wavelength of 365nm and ultraviolet light with the wavelength of 254nm for 60 seconds.

Description

technical field [0001] The invention belongs to the technical field of thin films, in particular to a preparation method of a multifunctional light scattering thin film. Background technique [0002] Organic light scattering materials have become important functional materials in the fields of lighting, optical display, and lighting design. They can not only solve the problem of viewing angle asymmetry inherent in liquid crystal displays, but also enable lighting and display systems to achieve high efficiency and visual uniformity. The purpose is to provide a guarantee for lighting and display equipment that combines high efficiency, low loss, high uniformity and perfect vision. Photochromism refers to the change of the molecular structure of certain compounds under the action of light of a certain wavelength and intensity, resulting in a corresponding change in the color of the light absorption peak, and this change is generally reversible. The photochromism of organic sys...
