摘要:
氧化石墨烯(GO)是化学氧化-还原法制备石墨烯的中间体,也是除石墨烯以外最为重要的二维纳米材料.由于GO纳米片表面富含各种含氧基团,因此其在水溶液中可以与多种物质发生超分子自组装,形成水凝胶.本文在分析GO化学结构的基础上,总结GO水凝胶的制备方法和形成机理,着重讨论GO的拓扑形状对水凝胶形成的影响,以及促进GO形成凝胶的超分子作用力,包括氢键、静电作用、配位作用、π-π作用等.最后,对GO自组装水凝胶的应用进行了评述,并展望了该领域今后的发展方向.
Abstract:
Graphene oxide(GO)is the precursor of chemically converted graphene,and also a very important two-dimensional nanomaterial.Owing to the various oxygen-containing functional groups on GO sheets,GO can form supramolecular hydrogels via three-dimensional self-assembly with diverse substances.In this review,after elucidating the chemical structure of GO,we reviewed the preparation methods and formation mechanism of GO hydrogels.The effects of two-dimensional shape of GO,and the supramolecular interactions which were commonly used to crosslink GO hydrogels,including hydrogen bond,electrostatic interaction,coordination and π-π interaction,were discussed comprehensively.Finally,the applications of graphene hydrogels were summarized,and future prospect in this area was also described.
