聚苯胺纳米纤维的合成及表征

摘要

With D-camphor sulfonic acid as a dopant , sodium dodecyl benzene sulfate as soft template , ammonium persulfate as the oxidant in the aqueous system , PANI nanofiber was prepared in situ polymerization of aniline and were characterized by UV, IR and SEM.Further research results showed that camphorsulfonic acid doped polyaniline nanofibers can promote the formation of PANI nanofiber , and also played the dual role of a dopant and a soft template .By controlling the reaction time , the product can be adjusted morphologies .%以D-樟脑磺酸为掺杂剂，十二烷基苯磺酸钠为软模板，过硫酸铵为氧化剂，在水溶液体系中通过苯胺原位聚合制备得到聚苯胺纳米纤维，对其进行了紫外和红外的表征，并使用SEM对其形貌进行了观测。进一步研究结果表明，樟脑磺酸的掺杂可促进聚苯胺纳米纤维的形成，并同时起到掺杂剂和软模板的双重作用；通过控制反应的时间，可调节产物的形貌结构。
