以石墨(G)含量为30％的高氯酸掺杂态聚苯胺(HClO4-PANI)为基体,掺入适量碳纳米管(CNTs),通过溶液共混合、机械球磨和冷压成型制备出聚苯胺/石墨/碳纳米管(HClO4-PANI/G/CNTs)复合热电材料.通过扫描电镜(SEM)、热重分析仪(TGA)和热电仪(ZEM)等对复合材料的结构和性能进行了表征.实验结果表明,HClO4-PANI/G/CNTs复合材料中各组分均匀地复合在一起,其ZT值随着CNTs含量的增加而先升高后降低.在90℃时,碳纳米管含量为7％的HClO4-PANI/G/CNTs复合材料的ZT值最高可达2.43×10-3,高于相同条件下石墨含量为37％的HClO4-PANI/G复合材料,比30％石墨含量的HClO4-PANI/G提高了7倍,比HClO4-PANI提高了3个数量级.
