与氧化石墨烯(GO)相比,修饰改性后的GO在有机溶剂中具有更好的相容性与分散性,其复合材料表现出的优异性能受到研究学者的关注。基于现有研究,简单介绍了非共价法、机械化学法、点击化学法、RAFT聚合法和硅烷偶联剂改性法等改性GO的制备方法,主要综述了改性GO在聚氨酯、环氧树脂、沥青、水泥等道路建筑材料中的应用研究进展,并对改性GO复合材料的未来发展进行展望。
Compared with Graphene Oxide (GO),the modified GO has better compatibility and dispersion in organic solvents,and the excellent performance of its composites has attracted the attention of researchers.Based on the existing research,this paper briefly introduced the preparation methods of modified GO such as the non-covalent method,mechanistic method,click chemistry method,RAFT polymerization method,and silane coupling agent modification method,and mainly reviewed the application research progress of modified GO in road building materials such as polyurethane,epoxy resin,asphalt,and cement.Finally,the future development of modified GO composites was prospected.
