An In Situ Oxidative Polymerization Method to Synthesize Mesoporous Polypyrrole/MnO Composites for Supercapacitors.

Manganese dioxide (MnO) shows great potential in the field of electrochemical performance. But its poor conductivity, easy dissolution in electrolytes and undesirable ionic accessibility hinder its application. The construction of mesoporous polypyrrole/manganese dioxide (PPy/MnO) composites can effectively alleviate these problems.
