A New and Simple Method for Manufacturing Electrochromic Tungsten Oxide Films
A new and simple method for the preparation of electrochromic tungsten oxide film is presented. This novel approach can be realized by introducing a nanoporous textured polyacrylic acid (PAA) layer between tungsten oxide layer and indium tin oxide (ITO) one by dip-coating process. Homogeneous film w...

| description | A new and simple method for the preparation of electrochromic tungsten oxide film is
presented. This novel approach can be realized by introducing a nanoporous textured
polyacrylic acid (PAA) layer between tungsten oxide layer and indium tin oxide (ITO)
one by dip-coating process. Homogeneous film with a thickness of about 0.8 μm is made
by single dipping a PAA-coated ITO glass in the WO3-NH4OH solution and shows an
X-ray amorphous structure. During the cathodic and anodic processes by chronopotentiometry,
the present films exhibit highly reversible electrochemical insertion of
lithium ions; the corresponding inserted charge of 12.5 mC/cm2 gives rise to a marked
blue color yielding the change in optical density (AOD) of 0.65 at 550 nm and a
coloration efficiency (η) of 51.8 cm2/C. |
