特殊的单原子层二维sp2碳结构给石墨烯带来众多独特的性能和潜在的应用.然而,单层石墨烯容易聚集并会逐渐重新石墨化,这成为其应用的一个重要障碍.本文报道了一种新策略来解决这个问题,即通过在石墨烯表面引入sp2碳纳米结构作为永久的波纹来阻止石墨烯的聚集和石墨化,并使之在溶液中易于分散和稳定.和其他功能化方法不同,该方法没有引入杂原子,不破坏石墨烯的结构和功能.制得的石墨烯具有优异的导电性能(～65000S·m-1),并具有较好的溶液稳定性.
Special single atom layer two-dimensional sp2 carbon structure to graphene brings many unique properties and potential applications.However, the single-layer graphene easily aggregated and will gradually re-graphitization, which became its application a major obstacle.This article reports A new strategy has been proposed to overcome this problem by preventing the aggregation and graphitization of graphene by introducing sp2 carbon nanostructures as permanent moiré on the graphene surface and making it easy to disperse and stabilize in solution. Different methods, the method does not introduce heteroatoms, does not undermine the structure and function of graphene. The prepared graphene has excellent conductivity (~ 65000S · m-1), and has good solution stability.
