Abstract
A graphene transparent conductive film is disclosed. The graphene transparent conductive film includes graphene and a vertical alignment agent. A method for manufacturing the graphene transparent conductive film is further disclosed. In the method, graphene, a surfactant, and water are mixed to obtain a graphene solution; a vertical alignment agent is added to the graphene solution to obtain a graphene transparent conductive film liquid, and the film liquid is coated on a substrate and heated to obtain the graphene transparent conductive film. The vertical alignment agent can reduce a surface energy of liquid crystal molecules in a polymer matrix, increase a contact angle, so that the liquid crystal molecules can be aligned vertically.
