Abstract

V₂O_x/PPTA composite film consisting of vanadium oxide (V₂O_x) and poly (p-phenylene terephthalamide) (PPTA) was prepared on ITO glass-coated with PPTA as described in the previous paper for WO₃/PPTA film.<br>Electrochemical, elctrochromic, and mechanical studies showed that V₂O_x/PPTA film had essentially the same electrochemical and electrochromic properties as V₂O_x film, but much greater mechanical strength (tensile strength: 86.3MPa, tensile modulus: 4.35GPa) and flexibility. We also found that V₂O_x film prepared this way was amorphous; on cathodic polarization, the color reversibly changed to green and on anodic polarization to yellow. If it acquires other intermediate colors as different potentials are applied, it may be used as a multicolor indicator.
