Abstract :Electrochromic display devices have been fabricated using Polydiallyldimethylammonium dihydrogenphosphate (PAMA+ H2PO4-) blended with H3PO4 as the electrolyte and WO3 as the electrochromic film. The WO3 deposited glass electrodes were doped with protons to form HxWO3 in which color depends on the charge density (CD) ranging from 0.01 to 0.04 C/cm2. Proton conducting films of PAMA+ H2PO4- 2 H3PO4 (2 moles of acid per polymer repeat unit) were sandwiched between two electrodes to obtain the following symmetric configuration: Glass/ITO/WO3/H+ -electrolyte film/HxWO3 /ITO/Glass. Prior to construction of the electrochromic windows, the electrochemical stability of polymer/acid blends was determined via cyclic voltammetry (CV).Keywords : Electrochromic Window, Poly(diallyldimethylammonium dihydrogenphosphate), Proton Conductor
