▎ 摘　　要

The paper reports an effective LB-based process to produce graphene oxide (GO). Uniform and controlled graphene oxide (GO) films were deposited on substrates by a simple and high-efficient Langmuir-Blodgett (LB)-based method. The influence of thermal reduction on GO films was systematically characterized and the annealing temperature of 800 degrees C was considered the most effective for reduction of GO. The optical and electrical properties were investigated for different reduced GO films to obtain the excellent sheet resistances of 440-620 Omega/sq with 60-70% range of light transparencies. A tunable surface wettability of GO films was found after heat treatment. (C) 2014 Elsevier B.V. All rights reserved.
