以苯胺（An）和吡咯（Py）为单体，采用表面活性剂辅助化学氧化聚合法一步合成了高长径比的聚苯胺-聚吡咯（PANI-PPy）纳米纤维。用过量PANI或PPy合成的PANI-PPy纳米纤维显示出与单独均聚物相似的光谱（紫外可见光和FT-IR）特征，而来自An和Py等摩尔混合物的纳米纤维显示出独特的光谱特征。PANI-PPy纳米纤维与金属离子发生自发的氧化还原反应，产生具有各种形态和/或尺寸的金属纳米颗粒。这些发现可能为合成具有可控尺寸和/或形貌的功能性聚合物纳米纤维和金属纳米颗粒开辟新的机会。
Polyaniline-polypyrrole (PANI-PPy) nanofibers with high aspect ratios have been synthesized by a one-step, surfactant-assisted chemical oxidative polymerization from mixtures of aniline (An) and pyrrole (Py) monomers. PANI-PPy nanofibers synthesized with an excess of either PANI or PPy show similar spectral (UV-vis and FT-IR) characteristics as the individual homopolymers, whereas nanofibers from an equimolar mixture of An and Py display unique spectral characteristics. PANI-PPy nanofibers undergo a spontaneous redox reaction with metal ions to produce metal nanoparticles with various morphologies and/or sizes. These findings may open new opportunities for synthesizing functional polymer nanofibers and metal nanoparticles with controllable sizes and/or morphologies.
