▎ 摘　　要

NOVELTY - Preparing graphene oxide paper involves soaking the filter paper with sodium chloride solution, coating the graphene oxide uniformly drop the graphene oxide solution onto the filter paper, so that the graphene oxide is spread out on the filter paper, placing in a thermostat to dry below 125 degrees C and peeling the graphene oxide from the filter paper. USE - Method for preparing graphene oxide paper used in the field of ion sieving, energy storage, electromagnetic shielding. ADVANTAGE - The method does not relate to expensive instrument, has good safety, good integrity, in cost-effective manner.
