摘要：NOVELTY - Preparing mesoporous carbon/polyaniline nanocomposite material, comprises mixing mesoporous carbon/silicon dioxide composite and then stirring, dispersing stirred mixture in sulfuric acid solution and then treating to make mesoporous carbon/silicon dioxide composite and then scattering, cooling the mixture in ice bath, weighing ammonium persulfate into deionized water and then cooling in a refrigerator, adding aniline monomer into obtained mixed system, adding ethanol solution in a vacuum and then stirring, and dropping obtained ammonium persulfate solution and then stirring. USE - The method is useful for preparing mesoporous carbon/polyaniline nanocomposite material and electrode material of super capacitor (claimed). ADVANTAGE - The method simply provides mesoporous carbon/polyaniline nanocomposite material with improved specific surface area, high specific capacity and stability, and excellent multiplying power performance in an economical manner. DETAILED DESCRIPTION - Preparing mesoporous carbon/polyaniline nanocomposite material, comprises mixing 0.05-0.3 g of mesoporous carbon/silicon dioxide composite and then stirring, and dispersing the stirred mixture in 5-30 ml of sulfuric acid solution (0.5-2 M) and then ultrasonically treating for 10-30 minutes to make mesoporous carbon/silicon dioxide composite and then fully scattering, and cooling the mixture in ice bath to obtain the mixed system, (2) weighing 0.25-0.85 g of ammonium persulfate into 5-20 ml of deionized water and then cooling in a refrigerator to obtain ammonium persulfate solution, (3) adding 0.1-0.6 g of aniline monomer into obtained mixed system, quickly adding 5-40 ml of ethanol solution in vacuum and then stirring for 30-90 minutes, dropping obtained ammonium persulfate solution and then stirring in ice bath, and reacting the stirred mixture for 5-24 hours and then filtering and washing, and (4) adding 5-40% of hydrofluoric acid in a silica particle and then drying.
