采用原位聚合法合成了导电聚苯胺/碳化硼（PANI/B4 C）复合材料。采用FTIR、XRD、TGA等方法对复合材料的结构和热稳定性进行了表征。结果表明，B4 C粒子与PANI粒子之间并非简单的共混，B4 C粒子与PANI粒子之间存在较强的相互作用。在PANI/B_4C复合材料中，PANI的结晶度增加，B_4C的衍射图几乎为无定形。复合材料的热稳定性优于纯聚苯胺。电导率测试结果表明，PANI/B4 C复合材料的电导率比纯PANI有很大提高，当B4 C含量为20wt%时，PANI/B4 C复合材料的电导率达到最大值35.6S·cm-1。
Conductive polyaniline/boron carbide (PANI/B4C) composites have been synthesized by in-situ polymerization of aniline in the presence of B4C particles. The structure and thermal stability of obtained composites were characterized by FTIR, XRD and TGA. The results showed that PANI and B4C particles were not simply blended, and a strong interaction existed at the interface of B4C and PANI. In the PANI/B4C composite, the degree crystalline of PANI increased and diffraction pattern of B4C was all but of amorphous. And that the composites were more thermally stable than that of the pure PANI. Electrical conductivity measurements indicated that the conductivity of PANI/B4C composites was much higher than that of the pure PANI and the maximum conductivity obtained was 35.6 S•cm-1 at 20 wt% of B4C.
