Abstract

Embodiments of films and material layers comprising PEDOT. These embodiments are the result of methods that utilize polymerization processes including vapor phase polymerization (VPP) to form the conductive film comprising PEDOT. In one embodiment, the film can result from a method that includes steps for depositing a coating solution onto a substrate, exposing the substrate to a monomer source, and cleaning the substrate after polymerization. The coating solution can comprise an initiating oxidant, which facilitates growth of PEDOT from 3,4 ethylenedioxythiophene (EDOT), as well as a quenching agent that neutralizes acid that results from polymerization.
