羧基功能化和表面活性剂修饰对石墨烯电化学性能的影响
Superior Electrochemical Performance of Graphene via Carboxyl Functionalization and Surfactant Intercalation
摘要
Abstract
Superior capacitance of carboxyl functionalized and surfactant-intercalated graphene were prepared by a relatively simple with two-step solution-based processing technique. In comparison to pristine graphene, surface car-boxyl functionalization and surfactant intercalation can tailor its specific capacitance from 50 F/g to 230 F/g. Mean-while, the modified materials retain more than 95% of their capacitance after 800 charge-discharge cycles, demon-strating good cyclic stability. Surfactant itself cannot improve the performance of pristine graphene as graphene inter-calated with surfactant has a specific capacitance of 45 F/g, however, carboxyl groups can dramatically enhance spe-cific capacitance to 130 F/g. The excellent performance of functionalized graphene emphasizes the importance of con-trolling its surface chemistry.关键词
