Comparative study on preparing carbon fibers based on PAN precursors with different comonomers

  • Zhang Wangxi
  • Liu Jie


Two different PAN precursors with various comonomers were wet-spun. The properties and structural changes of PAN precursors and their evolution during preoxidation and carbonization process were characterized by the use of DSC, FTIR and traditional parameters, e g, tensile strength. It is demonstrated that acrylamide (AAM) is very effective to make the DSC peak be separated compared to methyl acrylate(MA). As a result, carbon fibers developed from AAM-contained precursors have a better tenacity compared to those developed from MA-contained ones.
