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.

Complementary surface confined polymer electrochromic materials,

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.
