Graphene Oxide Membranes

Asymmetry of the reduced graphene oxide (rGO) membranes prepared by the commonly used vacuum filtration process is disclosed. When the filter membrane surface pores have similar dimension to GO sheets, the entry of GO sheets into its surface pore space during vacuum filtration can take place, leading to the asymmetry of the rGO membrane.

In this paper, reduced graphene oxide (RGO) was prepared by means ofγ-ray irradiation of graphene oxide (GO) in a water/ethanol mix solution, and we investigated the influence of reaction parameters, including ethanol concentration, absorbed dose, and dose rate during the irradiation. Due to the good dispersibility of the RGO in the mix solution, we built up flexible and conductive composite films based on the RGO and polymeric matrix through facile vacuum filtration and polymer coating. The electrical and optical properties of the obtained composite films were tested, showing good electrical conductivity with visible transmittance but strong ultraviolet absorbance.
