▎ 摘　　要

NOVELTY - Preparation of graphene oxide paper involves using a graphene oxide dispersion containing graphene oxide particles, reducing the graphene oxide paper, coating a metal salt on the reduced graphene oxide paper, and heating the metal salt-coated graphene oxide paper to form porosity in the paper. USE - Manufacture of graphene oxide paper used as material for electrodes of flexible energy devices, gas and biosensors, actuators, and membranes. ADVANTAGE - The method enables manufacture of graphene oxide paper with excellent conductivity, flexibility, and porosity.
