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.
