An Experimental Investigation on Polypyrrole Films Electro-Polymerized under a High Transverse Electric Field

Article Preview

Abstract:

Polypyrrole films were electrodeposited under different high transverse electric fields, and their film morphologies and functionalities were investigated. The surface morphology at the initial polymerization stage was investigated under AFM and the cross sectional morphologies of fully grown films were investigated by SEM. Both these microscopic investigations revealed the film morphology has been influenced by the applied transverse field. The cyclic voltammetry tests illustrate a reduction in the anodic peak voltage with the increase of transverse field. All these results suggest that the polymer electro-polymerized under a transverse high transverse electric field has some degree of pre-orientation compared to the films synthesized without a transverse electric field.
