Abstract
The electrical properties of conducting polymers are strongly dependent on their film morphology and chemical and physical structure, which in turn can be strongly modified via a variety of post-deposition treatments. The aqueous dispersion of poly(3,4-ethylenedioxythiophene) with polyelectrolyte, poly(styrene sulfonic acid) (PEDOT/PSS) was used as the conducting polymer in our study. We report an investigation of the conductivity and morphology of spin-coated films and their dependence on heat treatment procedures in both air and N
2 atmospheres.
