聚苯胺修饰石墨烯纳米片的分散行为
DISPERSION BEHAVIOR OF PANI-MODIFIED GRAPHENE NANOSHEETS OBTAINED BY REDUCTION OF GRAPHENE OXIDE
【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.
【Abstract】 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.
