石墨烯的优异性能使其在众多领域展现出巨大的应用潜力。然而,石墨烯在大多数溶剂中难以分散,不能与其他材料进行有效复合,难以充分发挥其优势,通常需要改性以获得能够满足特殊应用需求的性能。通过改性可以改变石墨烯的组成、尺寸、形状和结构等特征,从而调整其电子结构、溶解性、机械和化学性质,甚至赋予其新的性能。重点介绍了石墨烯的改性方法,及其用于复合材料制备的方法和应用,并对其今后在相关领域的发展趋势进行展望。
The excellent properties of graphene make it show great application potential in many fields.However,graphene is difficult to disperse in most solvents and cannot be effectively compounded with other materials,making it difficult to fully exploit its advantages.Therefore,modification is often required to achieve performance that can meet the needs of specific applications.Through modification,the composition,size,shape and structure of graphene can be changed,thereby adjusting its electronic structure,solubility,mechanical and chemical properties,and even endowing it with new properties.This paper focused on the modification methods of graphene,approaches in the preparation of composite materials,and their applications.It also discussed the future development trends in related fields.
