以钼酸为掺杂剂，过硫酸铵为氧化剂，采用自组装法制备了聚苯胺微/纳米结构。结果表明，掺杂浓度对PANI微/纳米结构的形态有一定的影响，即当钼酸与苯胺的摩尔比为0.01~1.5时，PANI的形态由纳米纤维转变为纳米纤维与微球共存。在相同条件下，PANI的电导率从4.5 8×10−3 S·cm−1提高到3.8×10−1 S·cm−1。用循环伏安法研究了PANI纳米纤维的电化学性质。用扫描电子显微镜对聚合过程中聚苯胺的形态进行了表征。发现当钼酸与苯胺的摩尔比为0.3时，聚苯胺的形态为纳米纤维与微球共存，且微球的形成先于纳米纤维的形成。
The polyaniline micro/nanostructure was prepared by a self-assembly process with molybdic acid as dopants in the presence of ammonium persulfate as the oxidant. It was found that the morphology of PANI micro/nanostructure was affected by the concentration of the dopant, that is, the morphology of PANI changed from nanofibers to co-existence of nanofibers and microspheres as the molar ratio of molybdic acid to aniline varied from 0.01 to 1.5. Under the same condition it was also found that the conductivity value of PANI enhanced from 4.58×10−3 S·cm−1 to 3.8×10−1 S·cm−1. The structure of PANI was characterized by FTIR and XRD which confirmed the presence of the molybdic acid in the PANI. The electrochemical characteristics of the PANI nanofibers were investigated by means of cyclic voltammetry. The morphology of PANI in the process of polymerization was characterized by SEM. It was found that when the molar ratio of molybdic acid to aniline was 0.3, the morphology of PANI was co-existence of nanofibers and microspheres and the formation of microspheres was ahead of the nanofibers.
