Abstract
The present invention provides a method for manufacturing a graphene composite electrode material, including the following steps: (1) providing a glass substrate, the glass substrate having a melting point greater than 1100° C.; (2) washing the glass substrate and then forming a metal film on the glass substrate; (3) patterning the metal film to form a circuit pattern; and (4) forming a graphene film on the circuit pattern so as to form a graphene composite electrode material. The method for manufacturing a graphene composite electrode material according to the present invention uses a temperature resistant glass substrate and a metal catalyst to directly grow a graphene film on a circuit pattern thereby requiring no transfer, not affected by solvent applied in transfer, having relatively high quality of film formation, requiring no etching, allowing for direct formation of a graphene composite electrode material, having a simple process, providing an effect of protection of the metal circuit pattern due to stable chemical property of graphene, and thus effectively extending the service life of the graphene composite electrode material.
