Polydopamine-coated graphene oxide (DGO) films exhibit electrical conductivities of 11,000 S m(-1) and 30,000 S m(-1) upon vacuum annealing at 130 °C and 180 °C, respectively. Conductive poly(vinyl alcohol)/graphene and epoxy/graphene nanocomposites show low percolation thresholds due to the excellent dispersibility of the DGO sheets and their effective in situ reduction.
经 130°C 和 180°C 真空退火处理后,多巴胺包覆氧化石墨烯(DGO)薄膜的电导率分别达到 11000 S m(-1)和 30000 S m(-1)。由于 DGO 片层具有优异的分散性和有效的原位还原,导电的聚(乙烯醇)/石墨烯和环氧/石墨烯纳米复合材料具有较低的渗流阈值。
