| 摘 要： | 用碘和高氯酸作掺杂剂对水溶性导电高分子聚（3-羧甲基噻吩）及其水凝胶的掺杂行为进行了系统研究。结果发现水溶胀聚（3-羧甲基噻吩）凝胶及其高分子很容易被高氯酸或碘的水溶液进行掺杂,且其掺杂能力强烈依赖于掺杂剂溶液浓度。对碘掺杂的高分子溶液,其掺杂过程不很稳定同时伴随着脱掺杂过程的发生,而对于聚噻吩凝胶,高氯酸极易使其掺杂,而且一旦掺杂则在掺杂状态下具有相对的稳定性。

| Abstract: | Doping behavior of water soluble conducting poly(3 thiopheneacetic acid)(P3TAA) and its gels were studied by using I 2 or HClO 4 solution as a dopant. It is found that the water swollen P3TAA gel and polymer can easily be doped by HClO 4 or I 2, and the doping effect shows a large dependence on the concentration of HClO 4 or I 2. The I 2 doped P3TAA solution is unstable accompanying with the dedoping reaction, however, the HClO 4 doped P3TAA gels are relative stable. |
