Graphene has attracted great interest for its outstanding mechanical

thermal

electrical and optical properties since it was found in 2004.Lots of polymer composites

based on graphene

were prepared and characterized

these researches show that the mechanical

electrical thermal and optical properties of polymer composites could be improved obviously for the addition of graphene.In this article

the research progress of graphene-based polymer composites was summarized.Especially

the preparation methods and properties of graphene-based polymer composites were described.The applications in biomedical science

solar cell and super-capacitor were introduced

and the developing trends and applying prospects of graphene-based polymer composites were also described.
