摘　　要：分别以草酸(OA)、氨基乙酸(AA)、乙二胺四乙酸(EDTA)为掺杂剂,以过硫酸铵为氧化剂通过自组装方法合成了聚苯胺纳米管。采用IR、XRD、UV-Vis、SEM、TEM和四探针法等测试手段对产物的结构、形貌和电学性能进行了表征。讨论了不同酸浓度对产物形貌及电学性能的影响。结果表明,当酸与苯胺的摩尔比为1∶2时,形成聚苯胺纳米管,草酸为掺杂剂时产物的电导率较高。Polyaniline nanotubes（PANI-NTS）were synthesized separately by a self-assembly method using oxalic acid（OA）,amino acetic acid（AA）,ethylenediamine tetraacetic acid（EDTA）as dopant and ammonium persulfate（APS）as oxidant and the products were characterized by IR,XRD, UV-Vis,SEM,TEM and 4-probes method.Effect of molar ratio of [Acid]and [An]on the morphology and electron conductivity was studied.It was found that nanotubes morphology were obtained when the[Acid]/[An]is 1∶2.The conductivity of PANI-NTS doped OA is preferable.
