摘　　要：以过硫酸铵（APS）为氧化剂，以对甲苯磺酸（TSA）为掺杂剂，通过快速混合法合成出对甲苯磺酸掺杂的导电聚苯胺（PANI／TSA）材料．以红外光谱（FTIR）、紫外-可见光谱（uV—Vis）和扫描电镜（SEM）对对甲苯磺酸掺杂的聚苯胺材料进行表征．分别测定了不同掺杂量的聚苯胺的导电率，结果发现对甲苯磺酸与聚苯胺的摩尔比为0．5时，该复合掺杂材料的电导率达到最高，其电导率为0．27S／cm．扫描电镜的结果表明对甲苯磺酸掺杂后的聚苯胺为片状结构，平均大小在200—300nm左右．Polyaniline （PANI）/p-toluenesulfonic acid （TSA） nano-composites were successfully fabricated by rapid mixing method, while ammonium persulfate （APS） was utilized as oxidant, and TSA was used as dopant. The PANI/TSA composites were characterized by FTIR, UV-Vis and SEM. The electronic conductivity of different doping concentrations of TSA in PANI was measured. As a result, the maximum electronic conductivity of the PANI/TSA composite is 0.27 S/cm when the molecular ratio of TSA and PANI is 0.5. The SEM results show that the images of the PANI/TSA nano-composite are flake powder, and particle size is approxi- mately 200 -300 nm.
