[0005] 3) The third type is organic antistatic liquid, which is usually a polymer compound, using conjugated π bonds, etc., to form a track for the flow of charged particles. The charged particle track formed by this antistatic liquid can only move in one direction. , which is the direction in which the polymer extends; compared with inorganic antistatic liquid, it can be better mixed with silicone oil to make the performance of silicone oil coating more stable; but the antistatic ability is weak, generally 10 11 Ω

Abstract

The invention relates to a preparation method of a polythiophene anti-static silicon release film. The polythiophene anti-static silicon release film comprises a base film layer and an anti-static release layer, wherein the base film layer is a transparent film of 25-150 microns, the surface of the base film layer is filled with nano-level fumed silica, and the outer surface of the base film layeris coated and adhered with the anti-static release layer; and a composition of the anti-static release layer contains polythiophene. The method uses a polythiophene anti-static liquid technology, asa structural unit of the film is a five-center six-electron large pi bond with six pi electrons, and conforms to a Huckel rule, the six electrons can all leave the domain and flow; as an induction effect and a delta-pi hyperconjugation effect exist, a single bond between the structural units has the characteristics of partial double bonds, and thus the whole system has the anti-static ability; andan orbit formed by the polythiophene is circular / linear alternating type, compared with common high polymer anti-static liquid linear orbits, as the circular part has two electron orbits, the anti-static ability of the film is better, and is not easy to damage.

Description

technical field [0001] The invention relates to the technical field of a release film, in particular to a preparation method of a polythiophene antistatic silicon-based release film. Background technique [0002] Release film, also known as peeling film, isolation film, separation film. Usually, in order to increase the release force of the plastic film, the plastic film will be treated with plasma, or coated with fluorine, or coated with silicon (silicone) release agent on the surface of the film material, such as PET, PE, OPP, etc. ;It can show extremely light and stable release force for various organic pressure-sensitive adhesives (such as hot-melt adhesives, acrylic adhesives and rubber-based pressure-sensitive adhesives). Because the release film has the advantages of isolation, filling, protection, and easy peeling, it is widely used in various fields such as electronics, communications, and machinery. Silicon-based protective film is a screen protective film mainly...
