抄録

V<sub>2</sub>O<sub>x</sub>/PPTA composite film consisting of vanadium oxide (V<sub>2</sub>O<sub>x</sub>) and poly (p-phenylene terephthalamide) (PPTA) was prepared on ITO glass-coated with PPTA as described in the previous paper for WO<sub>3</sub>/PPTA film.<br>Electrochemical, elctrochromic, and mechanical studies showed that V<sub>2</sub>O<sub>x</sub>/PPTA film had essentially the same electrochemical and electrochromic properties as V<sub>2</sub>O<sub>x</sub> film, but much greater mechanical strength (tensile strength: 86.3MPa, tensile modulus: 4.35GPa) and flexibility. We also found that V<sub>2</sub>O<sub>x</sub> 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.
