合成了一种兼具电致变色性能及离子电导性的新型梳型联吡啶聚合物PVSEO_(21)。测试了其修饰热解石墨电极在液体电解质中的循环伏安特性及其电致变色性能。该聚合物具有可逆性好、响应速度快等特点。其高速响应与聚合物本身的离子电导性有关。薄膜厚度为1.85μm时,该聚合物修饰电极在0～—0.8V和—0.8～—1.3V(vs.SCE)之间发生一电子和二电子氧化-还原反应,相应的电致变色响应时间分别为3ms和7ms。
A novel comb-type bipyridine polymer PVSEO_ (21) with both electrochromic and ionic conductivity was synthesized. The cyclic voltammetry and its electrochromic properties of modified pyrolytic graphite electrodes in liquid electrolyte were tested. The polymer has good reversibility, fast response and so on. Its high-speed response is related to the ionic conductivity of the polymer itself. When the thickness of the polymer film is1.85μm, one electron and two electron redox reactions occur between 0 ~ -0.8V and -0.8 ~ -1.3V (vs.SCE), and the corresponding electrochromic response time Respectively 3 ms and 7 ms.
