ABSTRACT:
In this experiment, graphene oxide was prepared by Hummers’ improved method, and water-soluble graphene oxide was prepared into graphene pure water film with a thickness of only 1 micron through pressure filtration. The thickness and densification of graphene membranes were controlled by improving pressure conditions and adjusting reduction degree, so as to achieve the expected nanofiltration grade of graphene pure water membranes that can be used to purify water. The graphene pure water film was successfully prepared, water pressure infiltration and pollution resistance experiments were carried out, and the preparation process was optimized by combining the experimental data.
