▎ 摘　　要

NOVELTY - Method for peeling polyimide film involves providing a multilayer graphene film between a substrate and a polyimide film, obtaining a substrate/multilayer graphene film/polyimide film laminate, applying Van der Waals force between graphene film layer as a sacrificial layer, destroying graphene film, and peeling the polyimide film from the substrate. USE - Method for peeling polyimide film. ADVANTAGE - The polyimide film is peeled without affecting properties of the polyimide film, with stable peeling effect, by simple process.
