Carbon-coated material was prepared by impregnation of a polymer and successive thermal treatment. Polymers such as phenol resin, polyacrylonitrile, polyvinylchloride and polivinylidene dichloride were used for impregnation and inorganic oxides such as SiO2, Al2O3, ZrO2 and TiO2 were used as supports. The amount of carbon coating was varied arbitrarily by changing the amount of polymer dissolved in the solvent for impregnation. Carbon-coated materials were characterized by TG/DTA, N-2 adsorption, mercury porosimetry and elemental analysis. Properties and structure of carbon-coated materials were discussed.
