Abstract
We report for the first time, a multilevel structure-property examination of three doped, unsubstituted polymers, polythiophene, polyaniline, and polypyrrole, deposited using oxidative chemical vapor deposition. Transmission electron micrographs (TEM) of each polymer not only indicate each forms a uniquely structured film, ranging from wires to symmetric platelets, but we also—for the first time—leverage energy dispersive TEM to examine the spatial distribution of the dopant atoms. The examination dives deeper and continues with a variable range hopping analysis of AC Hall data to calculate charge hopping distance and activation energy.
