Abstract
The present invention generally relates to compositions and methods for the preparation of conductive polymer coatings, and methods for application of the coatings to three-dimensional substrates.
Claims16
An electrically conductive polymeric coating on a substrate, wherein the electrically conductive coating is derived from a coating precursor composition comprising:
- a conductive polymer component comprising poly(3,4-ethylenedioxythiophene) and a primary counterion comprising repeat units, wherein one or more of the repeat units have a negatively charged functional group;
- a secondary doping agent;
- a crosslinking agent comprising 3-glycidyloxypropyl trimethoxysilane;
- a surfactant component;
- and
- a flexibility enhancer comprising poly(acrylamide-co-acrylic acid), polyvinylpyrrolidone, polyvinyl alcohol, polyethylene glycol, polyethylene oxide, or a combination thereof.
