AI Technical Summary
Existing methods for preparing graphene films suffer from long production cycles, high costs, and low efficiency. In particular, the traditional thermal reduction method is energy-intensive and requires stringent conditions, which hinders its large-scale production.
An electrochemical reduction method is employed, in which graphene oxide films are electrolyzed in an electrolyte solution. By selecting appropriate electrolysis modes and parameters, including constant voltage or constant current modes, and combining them with a three-electrode system, efficient reduction of graphene oxide can be achieved.
It shortens the preparation time of graphene films, improves reduction efficiency, reduces production costs, reduces energy consumption, and enhances the quality and production efficiency of graphene films.
