Abstract
The present invention provides a method for manufacturing a transparent conductive film and a method for manufacturing a CF substrate having the transparent conductive film. The method for manufacturing a conductive film includes: step: dissolving a mixed powder of graphene oxide and pure graphene in water and carrying out an ultrasonic treatment to obtain a stable aqueous solution of mixed graphene oxide and pure graphene; step: coating the stable aqueous solution of mixed graphene oxide and pure graphene on a substrate; step: subjecting the aqueous solution of mixed graphene oxide and pure graphene that is coated on the substrate to a drying treatment at 30-90° C. so as to obtain a film of mixed graphene oxide and pure graphene; step: applying a reducing agent to cause chemical reduction of the graphene oxide contained in the film of mixed graphene oxide and pure graphene so as to obtain a film of pure graphene, wherein the reducing agent is an ascorbic acid solution; and step: washing and drying the film of pure graphene obtained after chemical reduction so as to form a transparent conductive film on the substrate.
