NOVELTY - Preparing conducting chromatography film comprises (1) preparing graphene slurry oil according to a certain proportion, preparing aqueous solution of isopropanol, adding graphene dried powder-carboxymethyl cellulose (CMC) mixture, stirring at room temperature for 30 minutes to make it stable, where the isopropanol-aqueous solution ratio provides surface energy conditions for the stable and homogeneous dispersion of the graphene-CMC composite in the bulk phase, regulating the viscosity and hydration state of the oil slurry using CMC, regulating the density and conductivity of conductive coatings using graphene, (2) taking the graphene slurry oil on the paper base membrane and using graphene slurry oil supported on the film by printing and drying for many minutes at room temperature and can be used. USE - The method is useful for preparing conducting chromatography film. ADVANTAGE - The method is simple; has high efficiency; economical; high flexibility; has good conductivity and uniformly and stably coating.
