Research progress on reinforcing modification of epoxy resin

综述了近年来氧化石墨烯、碳纳米管、纤维素纳米纤维增强环氧树脂的研究进展。氧化石墨烯表面的含氧基团可与环氧树脂发生化学反应形成稳定的化学键,增加其在环氧树脂中的分散性。碳纳米管具有优异的力学性能,少量碳纳米管可显著提高复合材料的力学性能。纤维素纳米纤维含有大量的羟基、羧基基团,可与环氧树脂有效地结合。含氧基团的引入可显著提高材料的力学性能,在未来的研究中可将氧化石墨烯与纤维素纳米纤维结合,协同提高环氧树脂的力学性能。

The research progresses of epoxy resin reinforced by graphene oxide,carbon nanotubes and cellulose nanofibers in recent years were reviewed.The oxygen-containing group on the surface of graphene oxide could react with epoxy resin to form stable chemical bonds,which increased its dispersibility in epoxy resin.The carbon nanotubes had excellent mechanical properties,and a small amount of carbon nanotubes could significantly improve the mechanical properties of the composite.The cellulose nanofibers contained a large number of hydroxyl and carboxyl groups,which could be effectively combined with epoxy resin.The mechanical properties of epoxy resin were significantly improved by the introduction of oxygen-containing groups.In the future research,graphene oxide and cellulose nanofibers could be combined to synergistically improve the mechanical properties of the epoxy resin.
