吡咯在超细氧化锆 (IV) (ZrO2) 颗粒存在下聚合，该颗粒充当吡咯的分散剂。测量所得具有不同ZrO 2 颗粒浓度的聚吡咯-氧化锆(IV)纳米复合材料的室温电导率并与裸聚吡咯的室温电导率进行比较。结果发现，纳米复合材料的电导率高于不含 ZrO2 的聚吡咯，并且随着 ZrO2 浓度达到一定限度而增加。通过透射电子显微镜研究，获得了纳米复合材料和 ZrO2 颗粒的粒径和形态。
Pyrrole was polymerized in the presence df ultrafine zirconium (IV) oxide (ZrO2) particles which act as a dispersant for pyrrole. Room temperature conductivities of the resulting polypyrrole-zirconium (IV) oxide nanocomposites having different ZrO2 particle concentrations were measured and were compared with that of bare polypyrrole. It was observed that the conductivities of the nanocomposites were higher than that of the polypyrrole without ZrO2 and increased with ZrO2 concentration up to a certain limit. From transmission electron microscope studies, particle size and morphology of the nanocomposites and ZrO2 particles were obtained.
