NOVELTY - Preparation of graphene-polyimide conductive film involves (1) adding diamine to the graphene dispersion under the protection of protective gas, stirring until there are no particles, adding dianhydride in four batches, reacting for 1-2 hours at room temperature and stirring, (2) adding flame retardant modifier, stirring for 30-60 minutes, warming to 120-160 degrees C and reacting for 10-12 hours, (3) adding polar solvent to dilute the solution, stirring until homogeneous, filtering to remove impurities, (4) coating the solution obtained in step (3) on the substrate, drying to remove the solvent, carrying out imidization treatment, and stripping the substrate. USE - Preparation of graphene-polyimide conductive film (claimed).
