The morphology of doped polypyrrole.Cl powder changes dramatically from granular to nanofibrillar when a very small amount (1-4 mg) of V2O5 nanofibers are added to a chemical oxidative polymerization of pyrrole in aq 1.0 M HCl using (NH4)2S2O8 as the oxidant. Unlike the polyaniline system, a key synthetic requirement in the polypyrrole system is for the seed template to be "active", i.e., to be capable of independently oxidizing the pyrrole monomer. Thin, strongly adherent films can be obtained on inert surfaces such as glass, plastics, etc., directly from the polymerization mixture without any bulk product isolation steps, significantly simplifying the processing of these nanofibers.
当向在1.0 M盐酸水溶液中以过硫酸铵为氧化剂进行吡咯的化学氧化聚合反应中加入极少量（1 - 4毫克）的五氧化二钒纳米纤维时，掺杂聚吡咯.Cl粉末的形态从颗粒状急剧变为纳米纤维状。与聚苯胺体系不同，聚吡咯体系的一个关键合成要求是种子模板要“具有活性”，即能够独立氧化吡咯单体。无需任何本体产物分离步骤，直接从聚合混合物中就能在诸如玻璃、塑料等惰性表面上获得薄的、附着力强的薄膜，这显著简化了这些纳米纤维的加工过程。
