Growth Mechanism and Structure Analysis of Horn-like Polypyrrole

摘要

A novel horn-like polypyrrole (h-PPy) was electrochemically synthesized in alkaline solutions. With h-PPy films as the template, a highly porous composite of poly (3, 4-ethylenedioxythiophene) and h-PPy had been further electrochemically prepared, which turned out to be a promising energy storage and conversion material. [1] In this study, we investigated the growth mechanism and molecular structure of h-PPy. The horns were found as hollow and open during the early growing stage. The molecular chains of horns had an unexpectedly good ordering and great conjugation length.
