Abstract

Uniform, large-area hybrid transparent films composed of ultralarge graphene oxide (UL-GO) and functionalized single walled carbon nanotubes (SWNTs) are synthesized via a layer-by-layer Langmuir-Blodgett (L-B) assembly process. Before additional chemical doping, the GO/SWNT hybrid thin films deliver remarkable sheet resistance ranging 180-560 Ω sq-1 with optical transmittance ranging 77-86% depending on the number of hybrid layers. These optoelectrical properties are much better than the corresponding values of GO films prepared previously by the same technique, and the highest among all graphene, GO and/or carbon nanotube thin films reported in the literature, except graphene films synthesized by chemical vapor deposition on a Cu substrate. The L-B assembly technique developed here is capable of controlling the film composition, structure and thickness, highly suitable for fabrication of transparent conducting optoelectronic devices on a large scale without extra post-transfer processes.
