Abstract:
Graphite oxide was synthesized by the Hummer method, followed by ultrasonic delamination in water to produce a stable hydrosol of graphene oxide sheets. Then, a flowdirected assembly of this graphene oxide was produced in a celluloseacetatebased microfilter to form an ordered nanostructured membrane. The membrane was treated by chemical reduction and carbonization for deoxidation and regraphitization, which increased its electrical conductivity while retaining its shape. The graphenebased conductive membrane had a conductivity of 184.8S/cm. A reductive treatment before the carbonization increased the mass of residual carbon in the resulting membranes.
