Abstract

The invention relates to the technical field of flexible electronic film materials, in particular to a preparation method of a white graphene composite resin hardening solution and a PET hardening layer. The hardening solution includes parts by weight: 30-90 parts of polymer resin; 10-60 parts of diluent; 0.01-10 parts of photoinitiator; 0.1-15 parts of modified white graphene; the modified white graphene is 2 ~10 layers of white graphene are firstly treated with lipophilicity on the surface, and then modified by in-situ polymerization to obtain white graphene coated and modified by polymers. The hardening solution is coated on the surface of the PET base material, and after being thermally cured to form a film, it is then cured by ultraviolet light to obtain a white graphene-composite PET hardened layer. This application solves the phenomenon that the existing PET resin hardened layer is not wear-resistant, easy to scratch, large warpage, and oligomers or small molecules are precipitated; it can also solve the problems of transmittance, poor haze, Cracks are prone to occur in the back-end process, which leads to the failure of the conductive function.

Description

technical field [0001] The invention relates to the technical field of flexible electronic film materials, in particular to a preparation method of a white graphene composite resin hardening solution and a PET hardening layer. Background technique [0002] With the increasing demand for flexibility and thinning of electronic products, flexible, transparent, and high-strength plastic substrates have become the preferred materials for touch and display coating substrates. Compared with glass, PET material with high surface hardness, high toughness, and high light transmittance is already used by coating and coating manufacturers as the main optical film or explosion-proof film. But there are still many problems to be solved in the PET sold on the market at present. On the one hand, the PET optical film is easy to warp when it is resistant to high temperature, which affects the use, the mass production yield is low and the haze is high (compared to the glass light transmittanc...
