NOVELTY - The preparation method of graphene/silver nanowire transparent conductive film involves: (S1) preparing graphene oxide by improved Hummers method; (S2) dissolving the graphene oxide prepared in step (S1) in water, and carrying out ultrasonic dispersion to obtain graphene oxide aqueous solution; (S3) cleaning and drying a glass substrate, and carrying out surface treatment using (3-aminopropyl)triethoxysilane; and (S4) gradually spin-coating the obtained (3-aminopropyl)triethoxysilane modified glass substrate with graphene oxide aqueous solution and silver nanowire aqueous solution. USE - The method is useful for preparing graphene/silver nanowire transparent conductive film, which is useful in solar cells, flat panel displays or touch screens (all claimed). ADVANTAGE - The method prepares graphene/silver nanowire transparent conductive film with high stability. DETAILED DESCRIPTION - The preparation method of graphene/silver nanowire transparent conductive film involves: (S1) preparing graphene oxide by improved Hummers method; (S2) dissolving the graphene oxide prepared in step (S1) in water, and carrying out ultrasonic dispersion to obtain graphene oxide aqueous solution; (S3) cleaning and drying a glass substrate, and carrying out surface treatment by (3-aminopropyl)triethoxysilane to obtain (3-aminopropyl)triethoxysilane modified glass substrate; and (S4) gradually spin-coating the (3-aminopropyl)triethoxysilane modified glass substrate obtained in step (S3) with graphene oxide aqueous solution and silver nanowire aqueous solution, where the whole process is carried out in an inert gas atmosphere, drying the prepared thin film under vacuum, then putting into hydrazine steam for reduction, and finally carrying out heat treatment on the thin film to obtain product. An INDEPENDENT CLAIM is included for graphene/silver nanowire transparent conductive film prepared by the above method.
