Reduced graphene oxide-poly(3,4-ethylenedioxythiophene):p-toluene sulfonate (rGO-PEDOT:PTS) hybrid electrode films were synthesized directly on a substrate by interfacial polymerization between an oxidizing solid layer and liquid droplets of 3,4-ethylenedioxythiophene (EDOT) produced by electrospraying. The EDOT reduced the graphene oxide by donating electrons during its transformation into PEDOT:PTS, and hybrid films consisting of rGO distributed in a matrix of PEDOT:PTS were obtained. These rGO-PEDOT:PTS hybrid films showed excellent electrical conductivities as high as 1,500 S/cm and a sheet resistance of 70 Ω sq(-1). The conductivity values are up to 50% greater than those of films containing conductive PEDOT:PTS alone. These results confirm that highly conductive rGO-PEDOT:PTS hybrid films can potentially be used as organic transparent electrodes.

通过氧化固体层与电喷雾产生的3,4-乙撑二氧噻吩（EDOT）液滴之间的界面聚合，在基底上直接合成了还原氧化石墨烯-聚（3,4-乙撑二氧噻吩）：对甲苯磺酸盐（rGO-PEDOT:PTS）混合电极薄膜。在EDOT转化为PEDOT:PTS的过程中，它通过提供电子来还原氧化石墨烯，从而获得了由分布在PEDOT:PTS基质中的rGO组成的混合薄膜。这些rGO-PEDOT:PTS混合薄膜表现出高达1500 S/cm的优异电导率和70 Ω sq(-1)的表面电阻。其电导率值比仅含导电PEDOT:PTS的薄膜高出50%。这些结果证实，高导电的rGO-PEDOT:PTS混合薄膜有潜力用作有机透明电极。
