▎ 摘  要

Due to the scalability of production and the convenience in processing, graphene oxide (GO) has become an important precursor for the fabrication of transparent conductive films (TCFs). Developing a method to reduce the high contact resistance between the GO sheets, which is mainly due to the presence of a huge number of intersheet junctions, is the key for these applications. Here, we demonstrate a method of molecular level controlled fabrication of hybrid TCFs composed of 1-dimensional (1D) silver nanowires (Ag NWs) and 2-dimensional (2D) reduced graphene oxide (rGO) sheets. The ultra-large graphene oxide (UL-GO) sheets were transferred onto the quartz substrate via the Langmuir-Blodgett (L-B) method and then covered with Ag NW by the spin-coating method. The hybrid film was then reduced by chemical reduction using hydrazine hydrate. Upon varying the amount of Ag NW, the reduced UL-GO/Ag NW hybrid films show low sheet resistance ranging 13 to 48 Omega sq(-1) with optical transmittance ranging from 71.9% to 91.2%. The direct current (DC) to optical conductivity ratio of the hybrid films can reach up to 81, which is comparable to that of indium tin oxide (ITO).
