摘　　要：首先将改性碳纳米管经原位聚合制备得到了共价连接型聚苯胺/碳纳米管复合物;然后,通过水性掺杂的方法,获得水溶性、导电性优良的聚苯胺/碳纳米管复合材料。透射电子显微镜表明,聚苯胺/碳纳米管复合物的尺寸比纯碳纳米管明显增加;通过UV-vis光谱证实了CNT和PANI之间存在着强烈的相互作用。复合材料的电导率高达4.8×10^(-3)S/cm,比纯聚苯胺的电导率提高了一倍,并显示出优良的水溶性。The covalently-linked polyaniline （PANI）/carbon nanotube （CNT） composites were prepared by in- situ polymerization method from modified CNTs. Then, water-borne conductive PANI/CNT composites were ob- tained by doping in water. The diameter of PANI/CNT was obviously increased compared to pure CNT detected by TEM. The strong interactions between CNT and PANI were proved by UV-vis analysis. The conductivity of PANI/ CNT composites was as high as 4. 8 ×10^-3 S/cm, which is doubled compared with pure PANI, accompanied by the good water solubility.
