Electrochromic Properties of Co₃O₄/NiO Nanocomposite Films

Abstract:

Co₃O₄/NiO nanocomposite films were electrochemically synthesized on a ITO surface. The Co₃O₄/NiO nanocomposite films were characterized by energy-dispersive X-ray analysis (EDS) and scanning electron microscopy (SEM). The electrochromic properties of Co₃O₄/NiO nanocomposite films are investigated in an aqueous alkaline electrolyte (0.1M KOH) by means of transmittance, cyclic voltammetry (CV) and chronoamperometry (CA) measurements. The Co₃O₄/NiO nanocomposite films exhibit a noticeable electrochromism with reversible color changes, and fast switching speed (4.1 s and 3.6 s).
