| 摘 要： | 通过乳液聚合法制备纳米聚苯胺,使用十二烷基苯磺酸(DBSA)作为掺杂剂,在聚苯胺链上引入直链烷基,得到可溶性纳米聚苯胺(PANI-DBSA)复合物。研究了DBSA含量对PANI-DBSA复合物溶解度和电导率的影响,及制备过程中聚苯胺的生成和最终产物的紫外-可见光特征。结果表明:聚苯胺颗粒分散性好,粒径为20～100nm,当DBSA与苯胺单体摩尔比为3.0时,聚合物在甲苯中的溶解度最高为3.76%,当DBSA与苯胺单体摩尔比为1.0,聚合物导电性最好,电导率为250.4S/m。PANI-DBSA复合物在波长300～800nm具有良好的吸收性能。

| Abstract: | A soluble PANI-DBSA nanocomposite was synthesized through the emulsion polymerization method,by use of dodecylbenzene sulfuric acid (DBSA) as dopant and introducing a straight-chain alkyl in the polyaniline chain to increase the solubility of polyaniline.The influences of the DBSA content in polyaniline on the PANI-DBSA composites solubility and conductivity were investigated,and the formation of the polyaniline in the preparation process as well as the spectra situation of the final product were analyzed with UV-Vis spectroscopy.The results show that PANI-DBSA composites particles have good dispersion,the particle size is 20～100 nm.PANI-DBSA composities solubility in toluene reaches 3.76% and the best conductivity reaches 250.4 S/m when the molar ratio of DBSA and aniline is 3.0 or 1.0,respectively.Its absorption property is good at wavelength of 300～800 nm. |
