One-step fabrication of graphene-polyaniline (graphene-PANI) hybrid film was facilely achieved by cyclic voltammetric electrolysis of a bath containing both graphene oxide (GO) and aniline, where graphene is obtained by electrochemical reduction of GO and PANI is simultaneously obtained by aniline electropolymerization. As there is no strong attraction between aniline and GO under the electrodeposition conditions, the independent depositions of PANI and reduced GO nanosheets at their greatly differed potentials led to alternate layered graphene-PANI films, with the topmost layer being PANI particles or graphene sheets just by changing the initial scan directions. The two kinds of graphene-PANI hybrid films present excellent but different electrical and electrochemical behaviors.
一步法制备石墨烯-聚苯胺（graphene-PANI）杂化薄膜是通过循环伏安电解含有氧化石墨烯（GO）和苯胺的浴液来实现的，其中石墨烯是通过电化学还原 GO 得到的，而 PANI 则是通过苯胺的电聚合得到的。由于在电沉积条件下苯胺和 GO 之间没有强烈的吸引力，因此在它们的极大差异的电势下独立沉积的 PANI 和还原氧化石墨烯纳米片导致交替层状的石墨烯-PANI 薄膜，通过改变初始扫描方向，最顶层可以是 PANI 颗粒或石墨烯片。这两种石墨烯-PANI 杂化薄膜表现出优异但不同的电学和电化学性能。
