石墨烯具有优异的机械性能及导热性能,将其与聚合物结合制成复合材料,是发挥石墨烯优异性能最可行的方法之一。然而,石墨烯在聚合物中分散时易团聚,石墨烯功能化是解决这一问题最常用的方法。基于以上背景,重点介绍了石墨烯与氧化石墨烯的功能化方法,包括共价功能化和非共价功能化。同时,阐述了功能化石墨烯在改性环氧树脂力学性能和导热性能的应用现状。
Graphene(RGO) has excellent mechanical properties and thermal conductivity,in order to give play to these excellent properties,one of the most feasible ways is combining it with polymers to make nanocomposites.However,the bottleneck is that RGO sheets tend to form severe aggregations in the polymer,RGO functionalization is the most commonly used method to solve this problem.Thus,the functionalization methods of GRO and graphene oxide(GO) were focused,including covalent functionalization and non-covalent functionalization.The research status of RGO functionalization in the mechanical properties and thermal conductivity of modified EP was summarized.
