| 摘 要： | 通过氧化偶联聚合的方法我们制备了一种新型电活性聚芳醚砜，这种聚合物主链上含有苯基封端的苯胺四聚体齐聚物单元。我们通红外、核磁和XRD对其结构进行了表征。在1.0M的硫酸水溶液介质中我们对其电活性进行了研究，聚合物展现出两对氧化还原峰。此外，我们使用TGA测试手段对其热稳定性也做了研究。在室温质子酸掺杂的条件下聚合物的导电率为1.37 × 10-7 S·cm-1。

| Abstract: | By oxidative coupling polymerization a novel electroactive poly(ether sulfone), with fixed conjugated length of oligoaniline (phenyl‐capped aniline tetramer) in the main chain, was successfully synthesized. The structure of the electroactive poly(ether sulfone) was confirmed by FTIR, NMR spectroscopy and X‐ray powder diffraction (XRD). Electrochemical activity of the poly(ether sulfone) was tested in 1.0 mol·L?1 H2SO4 aqueous solution which shows two redox peaks. Moreover, the thermal properties of the poly(ether sulfone) were investigated by thermogravimetric analysis (TGA). Its electrical conductivity is about 1.37×10?7 S·cm?1 at room temperature upon preliminarily protonic‐doped experiment. |
