摘要
针对氧化石墨(GO)用化学方法还原为石墨烯纳米片(GN)后极易再配列为类似石墨结构层状物的问题,本工作在GO还原过程中用聚苯胺(PANI)修饰石墨烯纳米片(P-GN),发现即使干燥后,P-GN仍可在N,N-二甲基甲酰胺(DMF)中呈分散状态稳定存在.
Graphene nanosheets (GN), produced by chemical reduction of graphite oxide (GO), are easily aggregated, restacking to a graphite-like layered structure in liquid. To overcome this problem, the present work introduced polyaniline (PANI) during the GO reduction process to modify graphene nanosheets (P-GN). Data showed that even after drying, P-GN can still be stably dispersed in N, N-dimethylformamide.
