| Abstract:In order to improve the electrical conductivity and thermal conductivity of the carbon paper, the mesophase pitch-based carbon fibers with small electrical resistance and high thermal conductivity were used as a raw material to replace partially the polyacrylonitrile-based carbon fiber to prepare carbon paper. The effects of the proportion of mesophase pitch-based carbon fibers on the morphology, crystal structure, electrical conductivity and thermal conductivity of carbon paper were investigated. The results indicated that with the increase of the proportion of mesophase pitch-based carbon fiber, the degree of graphitization of carbon paper improved obviously, and the electrical conductivity and thermal conductivity increased significantly. When the mass ratio of mesophase pitch-based carbon fiber to polyacrylonitrile-based carbon fiber was 3:7, the degree of graphitization of graphitized carbon paper was 97.4%, its electrical resistivity decreased by 35.7% from 6.80 mΩ·cm to 4.37 mΩ·cm and the vertical surface thermal conductivity increased by 88.8% from 0.084 W/(m·K) to 0.159 W/(m·K) compared with graphitized pure polyacrylonitrile-based carbon paper. |
