Abstract

Colloidal particles of WO₃ and IrO₂ are synthesized and dispersed within a gelatinous perfluorinated ionomer matrix. Experimental procedures are established in order to obtain percolation between the electrochromic particles. Colloidal particle sizes are measured by quasi elastic light scattering. Electrochemical properties of the mixed colloid electrodes are determined by cyclic voltammetry and impedance spectroscopy. Preliminary optical tests are performed in order to measure transmission and contrast of electrochromic half cells with a mixed colloid electrode, and also a sputtered oxide electrode.
