  Abstract

Carbon fiber paper (CP) was prepared by wet forming technology, and liquid-phase polypyrrole/carbon fiber paper matrix composites (LPPY/CF) and gas-phase polypyrrole/carbon fiber paper matrix composites (GPPY/CF) were prepared by liquidphase polymerization and gas-phase polymerization on CP, respectively. Then the effects of dopant, oxidant and solubility of pyrrole (PY) on the resistivity of LPPY/CF and the solubility of ferric trichloride (FeCl 3 ) on the resistivity of GPPY/CF were discussed. Finally, the mechanical properties and thermal conductivity of CP, LPPY/CF and GPPY/CF were compared. The results show that: when ammonium persulfate (APS) and sodium anthraquinone-2-sulfonate (AQS) are used as oxidant and dopant, respectively, and pyrrole concentration is 0.75 mol/L, the resistivity of LPPY/CF is as low as 0.152Ω·cm; and when the solubility of FeCl3 is 1.2 mol/L, the resistivity of GPPY/CF is as low as 0.139Ω·cm. Compared with CP, not only the resistivity of LPPY/CF and GPPY/CF decreased signifi cantly, but also the mechanical properties, hydrophobicity, electrical conductivity and heating properties increased significantly. Compared with LPPY/CF, GPPY/CF not only has lower resistivity, but also has better mechanical properties and heating uniformity. However, due to the easy corrosion of PPY, GPPY/CF has poor long-term energy storage capacity.
