▎ 摘  要

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 flow-directed assembly of this graphene oxide was produced in a cellulose-acetate-based microfilter to form an ordered nanostructured membrane. The membrane was treated by chemical reduction and carbonization for deoxidation and re-graphitization, which increased its electrical conductivity while retaining its shape. The graphene-based conductive membrane had a conductivity of 184.8 S/cm. A reductive treatment before the carbonization increased the mass of residual carbon in the resulting membranes.
