Accurate analysis of the catalysis of ferric chloride in the preparation of graphene oxide film can improve the performance of the finished product. The thermal conductivity of graphene film prepared by the original method is low, so a new catalytic analysis method is proposed. Firstly, the flake double-layer graphite oxide is prepared by the improved Hummers method. Under the catalysis of FeC13, different reaction temperatures and reaction times are set to get the finished products of graphene oxide under different conditions. The structure characteristics of the finished products are analyzed, and the structure of that the graphene oxide films prepared at 90 degrees and 0.5h is determined to be the best. So far, the catalysis of ferric chloride in the preparation of graphene oxide film has been analyzed. The results show that the thermal conductivity of graphene oxide film prepared by catalysis is 900W/(m.K), which is higher than that of traditional products.
