ABSTRACT:
An electrochromic device includes a first substrate having at least one polymeric surface; a primer layer along the polymeric surface; a first electrically conductive transparent coating along the primer of the first substrate, wherein the primer layer adheres the first electrically conductive coating to the polymeric surface of the first substrate; a second substrate spaced apart from the first substrate to define a chamber therebetween; a second electrically conductive transparent coating on a surface of the second substrate such that the first coating is in facing relation to the second coating, wherein at least one of the first and second substrates is transparent; and an electrochromic medium contained in the chamber, the electrochromic medium having reduced luminous transmittance upon application of electrical power to the first and second conductive coatings and establishing an electrical potential through the electrochromic medium, and wherein the electrochromic medium and the primer layer are compatible.
