Title:
CONDUCTIVE POLYMER
Document Type and Number:
Japanese Patent JP2008171571
Kind Code:
A
Abstract:

To provide a conductive polymer superior in coulomb efficiency.

The conductive polymer has a branched polymer, especially hyperbranched polymer as a dopant. Since the branched polymer is doped to high polymer such as polypyrrole, a branched polymer anion is tangled with a polymer chain, the dopant is hard to be released, and an anion site is hard to be generated, thereby oxidation-reduction reaction (redox reaction) yields the conductive polymer which is formed by cation exchange of an electrolyte. Then, since response of adsorption/desorption of a conductive polymer ion is superior, the coulomb efficiency is more improved than a conventional conductive polymer.
