Multifunctional optical film and production method thereof

Abstract

The invention discloses a multifunctional optical film and a production method thereof. The multifunctional optical film includes a substrate, and an anti-reflection film layer, a chemically added hard coat layer and a physically added hard coat layer which are sequentially distributed on the surface of the substrate from inside to outside; The reflection film layer is a multi-layer anti-reflection film, including cerium oxide film layer, indium tin oxide film layer, silicon nitride film layer and silicon dioxide film layer distributed sequentially from the inside to the outside; Acryloyloxypropyl trimethoxysilane as a monomer, mixed with epoxy resin to form a wear-resistant film layer; the physical hardened film layer is a diamond film layer. Chemical hard coating and physical hard coating are used to increase the hardness of the surface of the optical film. The anti-reflection coating has a four-layer structure, which has a good effect, and the cerium oxide coating makes the optical film have a higher UV absorption rate and Good thermal stability can prevent the ultraviolet aging of the optical film, and the setting of the indium tin oxide film layer makes the anti-reflection film layer have conductivity, thereby obtaining an optical film with various functions.

Description

technical field [0001] The invention relates to the technical field of optical films, in particular to a multifunctional optical film and a production method thereof. Background technique [0002] Optical films are widely used in the field of optics and optoelectronics technology. Anti-reflection film is a common type of optical film. The structure of anti-reflection film in the prior art generally includes a substrate and an anti-reflection film layer arranged on the surface of the substrate. The substrate material is common It is Ge, Si, ZnS, ZnSe or chalcogenide glass, etc., and the anti-reflection coating material is usually magnesium fluoride, silicon dioxide, etc. The function of this type of anti-reflection coating is relatively simple and needs to be further improved. Contents of the invention [0003] In view of the above defects in the prior art, an object of the present invention is to provide a multifunctional optical film. [0004] In order to solve the above...
