以过硫酸铵（NH_4）_2S_2O_8为氧化剂，D-10-邻苯二磺酸（D-CSA）为掺杂剂，采用无模板法合成了直径为80-180 nm的导电聚苯胺（PANI）纳米管。研究了D-CSA与苯胺（An）的摩尔比、聚合介质中D-CSA的浓度、反应温度和反应时间等合成条件对聚苯胺（D-CSA）的形貌、尺寸及电性能的影响。结果表明，上述合成条件，特别是D-CSA与An的摩尔比，强烈影响所得聚苯胺的形态和形成概率。苯胺阳离子与D-CSA形成的胶束在PANI-（D-CSA）纳米管的形成过程中起到了模板作用。
Conducting nanotubes of polyaniline (PANI) about 80–180 nm in diameter were synthesized by a chemical template-free method in the presence of D-10-camphorsulfonic acid (D-CSA) as the dopant, and ammonium persulfate ((NH4)2S2O8) as the oxidant. The effect of synthetic conditions, such as the molar ratio of D-CSA to aniline (An), the concentration of D-CSA in the polymerization media, the reaction temperature and time, on the morphology and size as well as the electrical properties of the PANI–(D-CSA) was investigated. It was found that the above synthetic conditions, especially the molar ratio of D-CSA to An, strongly affected the morphology and formation probability of the resulting PANI. The micelles formed by D-CSA and anilinium cations act as the templates in the formation of PANI–(D-CSA) nanotubes.
