Abstract

The invention discloses a self-adhesion type dimming film. An outer protective layer, a first adhesive layer, a first conductive film layer, a polymer dispersed liquid crystal layer, a second conductive film layer, a second adhesive layer and a release layer are sequentially arranged from top to bottom. Multiple innovations in structure, material taking and formula are carried out; the film has the advantages of stability in operation, difficulty in damage, high transparency after being electrified and capability of being applied to curved surfaces; the dimming film can be installed by a useraccording to the requirements of the user, transformation of traditional glass is achieved, new and old replacement of the dimming film and modification of DIY decoration such as patterns are facilitated, material waste is avoided, time and labor are saved, the operation difficulty is low, the cost is low, comfort and convenience are brought to life of people, the application range is wide, and the market competitiveness is high.

Description

technical field [0001] The invention relates to the technical field of dimming films, in particular to a self-adhesive dimming film. Background technique [0002] As a new type of electronically controlled optical material, liquid crystal dimming film refers to the solidification of polymer dispersed liquid crystal between two transparent conductive films. In the absence of an electric field, the dimming film is in an opaque state. , the liquid crystal molecules in the dimming film are deflected, and the dimming film becomes transparent to realize dimming performance. Liquid crystal dimming film is the main material for making dimming glass. It is widely used. It is usually used in building exterior walls, real estate decoration, automobile glass, automobile rearview mirrors, projection curtain walls, office spaces, public entertainment facilities and other fields. It has privacy protection. Excellent properties such as security, space permeability, security and defense, an...
