Abstract: The polyimide provides high thermal stability，mechanical properties，electrical properties and chemical stability. Graphene which exhibits excellent physical properties and chemical properties is an excellent reinforcing material of composite. Filling of graphene into polyimide to make composite can improve the properties of polyimide composite to a large extent，which can meet the requirements of the high- tech product manufacture on material property. This paper presented a review of the research progress of polyimide modified with graphene and its derivative at home and abroad in recent years，and discussed emphatically on the preparation and modify methods of graphene，preparation method and properties of graphene-polyimide composite. Finally we prospected the development tendency of application of graphene-polyimide composite.

Key words: polyimide, graphene, graphene oxide, modification
