ABSTRACT
Conducting electroactive polymers (CEPs) such as polypyrrole, polythiophene, polyaniline, and sulfonated polyaniline (1-4 shown subsequently) are complex, dynamic structures that captivate the imagination of those of us involved in intelligent material research.1,2,3,4,5
(The number of monomer units per unit positive charge is usually 3-4 for polypyrrole and polythiophene. A− is a counterion incorporated during synthesis.)
Polyaniline: leucoemeraldine (y = 1), emeraldine (y = 0.5), and pernigraniline (y = 0); m determines the molecular weight.
