▎ 摘　　要

NOVELTY - Preparation of bacterial cellulose-reinforced graphene oxide paper involves (1) taking graphene oxide hydrosol, copper chloride dihydrate and bacterial cellulose into methanol, and uniformly dispersing the graphene oxide and bacterial cellulose in methanol by ultrasonically dispersing to obtain suction filtrate, (2) pouring suction filtrate into the suction filtration device for suction filtration, removing suction filtration membrane attached with bacterial cellulose reinforced graphene oxide paper after the suction filtration is completed, (3) slightly bending the edges of suction filter membrane to make the resulting bacterial cellulose-reinforced graphene oxide paper such that the obtained bacterial cellulose-reinforced graphene oxide paper gradually fall off the edges naturally after drying the suction filter membrane attached with bacterial cellulose-reinforced graphene oxide in the air. USE - Preparation of bacterial cellulose-reinforced graphene oxide paper used in preparation of flexible films (claimed). ADVANTAGE - The bacterial cellulose can improve the suction filtration efficiency of graphene oxide paper, and is beneficial to large-scale production, and can enhance the mechanical strength of graphene oxide paper. The preparation process is simple and convenient and is suitable for large-scale industrial production and promotion.
