Problems solved by technology

Existing polythiophene is used as a conductive electrode, which will fail due to contact with moisture in the air or volatile solvents; secondly, the traditional PEDOT / PSS has strong acidity as a whole because it uses PSS as a balance ion, which leads to problems in electronics, display, etc. Limits applications, while its own conductivity is relatively low; on the other hand, when this conductive solution is applied, its adhesion to flexible substrates is relatively low
In addition, when the existing conductive electrodes are applied to liquid crystal tablet, flexible LCD, and flexible electronic paper, the box thickness of 3-8 microns will cause local short circuit in actual production and manufacturing, which will easily lead to the failure of the entire device

Abstract

A method for preparing a conductive solution of a conductive electrode and a method for preparing a conductive electrode are provided. The method for preparing the conductive solution of a conductiveelectrode comprises forming a first solution by polymerizing acrylate and styrene sulfonate to form a polymer and adding a proper amount of deionized water; then fully dispersing the conductive polymer monome EDOT into the first solution for chemical reaction to form a second solution PEDOT-polymer solution, adding an appropriate amount of an aqueous solution containing silicon to the second solution to form a third solution, and uniformly coating the UV-treated flexible substrate with the third solution in a coating manner, and finally solidifyiung the same. During the solidification, the surface of the flexible substrate on the PEDOT-polymers in the polymer have a natural affinity, so PEDOT-polymer is gradually deposited on the surface of the substrate, the silicon-containing material issqueezed onto the upper lay, so that the effect after curing is that the lower layer is an electrically conductive layer and the surface layer is a hydrolyzed silicon dioxide network, thereby havingan insulating and protective effect.
