Scientists and research units around the world at present are dedicated to the study on how to improve the energy density and power density of super capacitor, shorten the charging and discharging time? However, the key to solve these problems is to find a good super capacitor electrode material. Graphene has the good electrical conductivity, the large specific surface area and strong mechanical strength.Graphene in the field of super capacitor electrode materials showed great application prospect. At present, for the sake of large-scale, low-cost preparation of graphene, chemical reduction of graphene oxide is used. However in the process of reduction, a traditional hydrazine hydrate reductant is toxic, environmental pollution, and the as-prepared graphene is easy to renite, severely limiting the graphene and graphene composite application. Therefore, this paper based on the analysis of graphene based onrecent research and application of the results, carried out a water soluble graphene and graphene-conductive polymer binary composite, graphene-conductive polymers-transition metal oxides ternary composites.KEY WORDS: GRAPHENE, GRAPHENE OXIDE, POLYANILINE, SUPERCAPACITOR, INTERFACIAL POLYMERIZATION, COMPOSITE.正文：随着时间地推移，人口必然会逐步增加，人们对于汽车的持有量也必然会成倍地增加。然后随着汽车的增加，必然会带来三大问题，能源问题、二氧化碳排放造成的温室效应问题和空气质量问题。目前，应对这些问题最好的方法是取消或者替代以石油为燃料的汽车，所以
