石墨烯表面聚合物改性及应用研究进展

Progress in preparation and application of graphene/polymer composite material

利用聚合物对石墨烯进行表面改性,能有效避免石墨烯层间堆积并提高其在溶剂及聚合物基体中的分散性,从而使其优异的理化性能得到充分发挥。综述了通过非共价和共价两种方法对石墨烯进行表面改性的研究进展,讨论了所制备石墨烯/聚合物复合材料在传感器、高强度材料和能源等领域中的应用。

Polymer modification is better method for surface modification of graphene,which can effectively avoid the stack between graphene layers and improve the dispersibility of graphene in the solvent and polymer matrix. Thus the excel- lent physical and chemical properties of graphene can been given into full play. The non-covalent and covalent modification methods to prepare the graphene/polymer composite materials were reviewed. And their applications in fields of sensors, high-strength materials and energy were also discussed.
