▎ 摘　　要

NOVELTY - Graphene/polyvinyl alcohol composite elastic film is claimed. The graphene/polyvinyl alcohol composite elastic film is prepared by carrying out reduction of graphene oxide by tannic acid under heating conditions, and connecting cross-linking agent, polyvinyl alcohol and graphene to form graphene/polyvinyl alcohol composite elastic film as network structure. USE - The elastic film is useful for sensors, artificial muscle and drug controlled release fields. ADVANTAGE - The elastic film: has enhanced mechanical property, excellent tensile recovery property, and resilience performance; and the method has mild reaction conditions, and simple synthesis step; and is suitable for large-scale industrial production.
