摘要
石墨烯高分子化在发展高性能聚合物基纳米功能材料方面备受关注。追踪近几年与超支化聚合物/石墨烯复合材料相关的文献,针对超支化聚合物对石墨烯的共价和非共价功能化改性方法进行了综述。将共价功能化细分为表面功能化和边缘功能化,以及非共价功能化分为通过π-π作用超支化聚合物吸附在石墨烯表面和通过疏水作用超支化聚合物对石墨烯的剥离这两种情况。并简单介绍了超支化聚合物功能化的石墨烯基复合材料的性能和应用,对其存在的问题和未来的发展方向进行了展望。
Research on functionalization of graphene with polymers has been attracted an increasing interest due to their potential applications in polymer-based functional nanomaterials. Tracking the literatures in recent years related to hyperbranched polymer /graphene composites,the methods for the covalently and non-covalently functionalized graphene sheets with hyperbranched polymers are reviewed.The former is further classified based on chemical bonds formed on the edge of graphene and formed on the surface of graphene,and the latter concerns the physical adsorption of hyperbranched polymers to the surface of the graphene via π-π interactions and exfoliation of the graphene by hydrophobic interactions.In addition,properties and applications of composite materials is introduced briefly,and the existing problems and development direction in the future is prospected.
