摘要

以吡咯为单体，用化学氧化法和电化学沉积法分别制备聚吡咯（PPy）纳米粒子和微球。实验表明，PPy-ED微球的比电容要优于PPy-CS纳米粒子，并且PPy微球表现出理想的赝电容行为，可以进行快速可逆的法拉第反应，其原因在于PPy微球分子链规整，具有较大的共轭程度，从而表现出优异的电化学储能性。

Abstract

Polypyrrole (PPy) with different morphologies were prepared by chemical oxidation and electrochemical deposition. The experimental results showed that specific capacitance (SC) of the PPy microspheres was better than PPy nanoparticles

and exhibited typical pseudocapacitance behavior

which can quickly proceed the reversible Faraday response in redox reaction. The reason was attributed to the order molecular chains present in the PPy microspheres

which was in favor of forming the larger conjugated system in the PPy microspheres

and showed excellent property in electrochemical energy storage.
