Infos

This book outlines methods to improve functioning of these polymer based devices - in particular, the multi-faceted cognition of these materials. In situ electrochemical techniques are studied to elucidate redox switching between non-conducting and conducting states.
The book examines the advantages of combinations of in situ electrochemical techniques in a hyphenated mode for analyzing conducting polymers.
