Abstract

The invention discloses a composition, a polymer dispersed liquid crystal, a thin film and electronic equipment, the composition comprises a polymer monomer, a liquid crystal and a photoinitiator, the polymer monomer comprises a high-functionality compound, and the functionality of the high-functionality compound in the polymer monomer is not less than 4. Therefore, the polymer dispersed liquid crystal with higher binding force can be prepared from the composition.

Description

technical field [0001] The invention relates to the field of electronic equipment, in particular to a composition, a polymer dispersed liquid crystal, a thin film and an electronic equipment. Background technique [0002] Polymer-dispersed liquid crystal materials have the characteristics of safety, energy saving, low power consumption, intelligent dimming and convenient use. They are usually used in scenarios such as smart projection glass, bathroom smart glass, smart dimming curtain glass, and smart home glass. The polymer-dispersed liquid crystal film is sandwiched between two layers of glass, or laminated to the unstressed inner surface. The polymer-dispersed liquid crystal layer in the related art has weak binding force and cannot be applied to more application scenarios. [0003] Therefore, current compositions, polymer-dispersed liquid crystals, thin films, and electronic devices still need to be improved. Contents of the invention [0004] This application aims t...
