| Abstract:Lignin hasrich sources in the nature, and contains a large amount of carbon content, which can be used as a carbon source for the preparation of graphene. Lignin also contains many functional groups which can play an important role in the preparation of graphene composite materials. This article briefly described the properties of lignin and graphene, the preparation methods of graphene composite. The research progress of preparation of graphene composites using lignin as carbon source or matrix was mainly discussed, including lignin-graphene functional composite, graphene energy storage materials, graphene quantum dots, etc. The expectation for the applications of lignin in graphene composite materials was presented as well． |
