Polypyrrole (PPy) is oxidatively polymerized in the frozen state at −24 °C in the presence of various organic dyes as morphology guiding agents in order to form homogeneous 1D PPy nanoforms. The freezing polymerization of pyrrole has a significant influence on the electrical conductivity and thermal stability but negligible influence on the yield compared to widely used room temperature polymerization.

冷冻状态聚合作为提高聚吡咯电导率的工具。

为了形成均一的一维PPy纳米形式，聚吡咯（PPy）在冷冻状态下于-24°C于各种有机染料作为形态学引导剂进行氧化聚合。与广泛使用的室温聚合相比，吡咯的冻结聚合对电导率和热稳定性有重大影响，但对收率的影响可忽略不计。
