1前言全球变暖和能源枯竭是当今社会发展过程中面临的巨大挑战[1,2]。开发可持续和再生能源已成为解决能源危机和保护环境的重要措施，而太阳能、风能、氢能等输出不稳定，因此需要有效的储能装置能够存储能量并在需要时进行稳定供给[3]。同时，电网储能、移动通信、医疗器械、城市轨道摘要：超级电容器已成为最具应用前景的电化学器件之一，可以快速的存储和释放电能。石墨烯凭借其优异的力学、电学、热学等优点成为超级电容器理想的电极材料。然而，由于范德华力的存在，石墨烯电极在制备过程中容易出现聚集和堆叠，进而导致材料的比表面积和电导率大幅度降低，严重影响其电容性能。对石墨烯进行功能化修饰，并且与其他材料复合可有效解决上述问题。本文对氧化石墨烯基、还原氧化石墨烯基和羧基化石墨烯基复合材料的电容性能的研究进展进行了介绍。关键词：超级电容器；电极材料；功能化石墨烯；电容性能中图分类号：O631文献标志码：A文章编号：2096-854X（2022）06－0019-05ResearchProgressonCapacitancePropertiesofFunctionalizedGraphene-basedCompositesWuRongfang1，2，LiNa2，LiuPeipei2，3，*（1.SchoolofPharmacy,JiangxiScienceandTechnologyNormalUniversity,Nanchang,330013,Jiangxi,P.R.China;2.InstituteofFlexibleElectronicsInnovation,JiangxiScienceandTechnologyNormalUniversity,Nanchang330013,Jiangxi,P.R.China;3.SchoolofCommunicationandElectronicsJiangxiScienceandTechnologyNormalUniversity,Nanchang,330013,Jiangxi,P.R.China）Abstract:Supercapacitorisoneofthemostpromisingelectrochemicaldevicesthatcanquicklystoreandreleaseelectricalenergy.Graphenehasbecomeanidealelectrodematerialforsupercapacitors,duetoitsexcellentmechanical,electrical,thermalandotherproperties.However,graphene-basedelectrodesarepronetoagglomerationandstackingduringthepreparationbecauseofthevanderWaalsforces,resultinginalargedecreaseinthespecificsurfaceareaandelectricalconductivityofthematerial,andaffectingit’sthecapacitanceperformanceseriously.Therefore,manyresearchersfocusonfunctionalizinggrapheneandcompositingwithotherelectrodematerialstosolvetheaboveproblems.Inthispaper,theresearchprogressonthecapacitivepropertiesofgrapheneoxide-based,reducedgrapheneoxide-basedandcarboxyl...
