SUBSTRATE FILM FOR TRANSPARENT ELECTRODE FILM PRODUCTION

摘要

The present invention relates to a technique for producing a transparent electrode film by forming transparent electrode raw materials such as a conductive polymer, carbon nanotubes, graphene and metallic nanowire on the surface of a transparent substrate of polyester or the like; wherein, in order to reduce changes in the surface resistance of the transparent electrode film during edge testing, a photocurable resin layer is formed on the surfaces on both sides of the substrate film, and a transparent electrode layer is formed on the surface on one face thereof. Here, the technique involves adjusting the degree of photocuring of the photocurable layers formed on the surfaces on both sides of the substrate film such that the degree of curing of a face on one side is at least 85%, and the degree of curing of the photocurable resin layer on the opposite surface is between 45 and 85% and then forming the transparent electrode layer on this surface.
