Abstract: Electrochromic device having electrode surface confined complementary polymer electrochromic materials, and materials, systems and methods of fabrication therefore. The electrochromic devices employ a polypyrrole-prussian blue composite material on the oxiatively coloring electrode, and a heteroaromatic substance containing at least one quaternized nitrogen atom group on the reductively coloring electrode. A bilayer material consisting substantially of metallic oxide which is conductive in at least one of its redox states and electroplated with a polymer is also disclosed for use as an electrochromic material on either the oxidatively colored or reductively colored electrodes. A method for electrodeposition of viologen polymers at a substantially neutral pH is also disclosed. A method for self-powering and self-modulating electrochromic devices by means of photovoltaic cells is also disclosed.

Abstract: A display having an array of matrix addressable pairs of electrodes mounted face up on the same substrate. The pairs of electrodes are derivatized with either electrochromic materials or electroluminescent material to form the pixels of the display. In the electrochromic embodiment of the invention, a layer of a solid polymer electrolyte is included. The air of electrodes may also be left clean of derivatizing material, but with an electroluminescent substance dissolved in the solid polymer electrolyte. An electrochemiluminescent embodiment is also provided where the electrochemiluminescent substance can be dissolved in the solid polymer electrolyte.

Abstract: The disclosure relates, inter alia, to a composition and, a method of making the composition. The composition comprises an electrically conductive polymer having a porous structure and a compound formed in situ and coating at least a portion of the surfaces of said polymer. The method of making the composition comprises forming an electrically conductive polymer having a porous structure, contacting the surfaces of the polymer with a solution comprising chemical species capable of being electrochemically formed into a coating material on the surfaces of said structure and electrochemically forming the coating material on the surfaces of the structure.
