| Abstract: | Several polyacrylate matrixes were prepared with monomers such as methyl methacrylate, KH-570, acrylic acid and butyl acrylate, and the electrochromic behavior of their soluble PAn composite coatings was also studied by electrochemical analysis and spectrophotometry. It shows that the constitution of the polymer matrixes have great effects on the electrochromic process and the color change of the composite coatings. When the matrix consists of acrylic acid unit, PAn of both interior and exterior composite possesses the same electrochemical reactivity, shorter responding time and wider color-changing range. But it is contrary when matrixes contain no acrylic acid. Furthermore, the composite containing acrylic acid units has still electrochemical reactivity in distilled water instead of LiCIO,-PC electrolyte. |
