Abstract
Photocurable, conductive, and transparent polymer coating compositions and methods of using the same are provided. The compositions include a photopolymer and an electrically conductive polymer dissolved or dispersed in a solvent system. Preferred photopolymers include water-miscible, multifunctional acrylates. Preferred electrically conductive polymers include poly(3,4-ethylenedioxythiophene)/poly(styrene sulfonate) (PEDOT-PSS). The compositions preferably also contain a photoinitiator and may contain a water-immiscible acrylate and/or a surfactant. The compositions are applied to substrates and exposed to actinic radiation such as ultraviolet (UV) light to form a cured, durable, conductive, and transparent coating.
