Abstract: Combining the electrical conductivity and special vesicular structure of bamboo charcoal(BC)with the electrical conductivity of polyaniline(PANI), the conductive composite of polyaniline/bamboo charcoal was prepared through in-situ polymerization(PANI/BC). The influences of reaction factors on electrical conductivity of the composite were studied. The electrical conductivity, molecular structure and microscopic pattern of the composite material were characterized by four-point probe, FT-IR and SEM. The results showed that under the condition of aniline dosage 1mL, APS 6.9g, BC 3g, HCl concentration 1mol/L, reaction temperature 0℃,the electrical conductivity of the composite was 22.5S/cm。The improvement of the electrical conductivity of the composite was due to the formation of the good electro-conductive circuit between BC and PANI.
