摘要： 利用竹炭(BC)的导电性和特殊的多孔结构,结合聚苯胺(PANI)的导电性,通过原位溶液聚合法制备了具有导电性能的聚苯胺/竹炭(PANI/BC)复合材料,考察了各种反应条件对复合材料电导率的影响。利用四探针、红外光谱、扫描电镜对复合材料的导电性能、分子结构、微观形貌进行表征测试。结果表明:当苯胺用量为1mL,引发剂过硫酸铵(APS)为6.9g,竹炭3g,盐酸浓度为1mol/L,反应温度控制在0℃时,得到复合材料的电导率为22.5S/cm,复合材料导电性能的提高是由于竹炭和聚苯胺之间形成了良好的导电通路。

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.

Key words: bamboo charcoal, polyaniline, composite, in-situ polymerization
