Beschreibung
Zusammenfassung:	The invention discloses a graphene thin film, a graphene super capacitor and a preparation method of the graphene thin film and the graphene super capacitor, and aims at solving the common problems of defects of long time taken, high energy consumption, not easy large-batch preparation and the like of a graphene preparation method in the prior art. The preparation method of the graphene thin film comprises the following steps: coating a metal substrate with a graphene oxide solution; obtaining a graphene oxide thin film dried and cured on the metal substrate under preset conditions; performing laser carving reduction processing on the graphene oxide thin film to obtain the graphene thin film; separating the graphene thin film from the metal substrate.
