Problems solved by technology

[0005] However, the transparent conductive film prepared with PEDOT:PSS conductive ink has the problems of easy scratching and poor adhesion to the substrate, which seriously limits the application of PEDOT conductive film in industry. It is necessary to realize the large-scale production of PEDOT conductive film , Improving the adhesion between the film and the substrate and the scratch resistance of the film are technical barriers that cannot be bypassed

Abstract

The present invention discloses a method for improving PEDOT conductive thin film adhesive force and a damage-resistant performance. The method comprises the steps of: doping resin and resin curing agent in the conductive ink; coating the conductive ink to generate a conductive layer on the base materials; performing annealing and curing processing of the conductive layer; doping the resin and theresin curing agent in the PEDOT dispersion liquid, after filming of the conductive ink on the base materials, performing annealing process, performing crosslinking reaction of the resin and the curing agent under the high temperature to form a net space polymer, wherein, if the net space polymer is distributed in the PEDOT film in a skeleton mode, the adhesive force and the damage-resistant performance of the PEDOT film can be obviously improved. The resin is high in transmission of light, cannot generate influence for the transmission of light of the film, and the toughness is excellent after resin curing so as to obviously improve the flexibility of the PEDOT film.

Description

technical field [0001] The invention relates to the field of organic optoelectronic technology materials, in particular to a method for improving the adhesion and scratch resistance of a PEDOT conductive film. Background technique [0002] Optoelectronic devices such as light-emitting diodes, solar cells, touch panels, etc. have been widely and important used in many fields. Optoelectronic devices require at least one transparent electrode in order for the optoelectronic device to absorb or emit light. Indium tin oxide is currently the most commonly used transparent electrode material. However, the scarcity of indium, the high requirements for the preparation of indium tin oxide thin films, and the inherent brittleness of indium tin oxide have greatly affected its future applications. Therefore, there is an urgent need to find new transparent conductive materials to replace indium tin oxide. [0003] Poly(3,4-ethylenedioxythiophene) (PEDOT) was synthesized for the first ti...
