在稳定的水-油微乳液中成功合成了纳米聚苯胺粒子。红外光谱表明，在酸性反应介质中，十二烷基苯磺酸钠（SDBA）既起表面活性剂的作用，又起掺杂剂的作用。广角X射线衍射、紫外-可见光谱和热分析表明，在微乳液体系中合成的聚苯胺结晶度显著提高，而助表面活性剂的链转移反应降低了聚合物链上的沿着π共轭长度。
Nanoscopic polyaniline particles were successfully synthesized in a stable water–oil microemulsion. FT-IR spectra showed that sodium dodecylbenzenesulfonate (SDBA) acted both as surfactant and dopant in the acidic reaction media. Wide-angle X-ray diffraction, UV–visible spectra and thermal analysis suggested that the crystallinity of PANI synthesized in the microemulsion system was increased dramatically while the chain-transfer reactions of co-surfactants decreased the π-conjugation length along the polymer chain.
