摘要: 通过分子设计, 利用A2+B3反应合成了一种新型电活性超支化聚合物材料. 该材料在保持聚苯胺的电活性基础上, 还具有超支化聚合物特有的低黏度(其特性黏度为0.33 dL/g)、低结晶性及良好的溶解性. 利用紫外-可见光谱对聚合物的氧化过程进行了监测. 热失重分析显示, 该材料具有较好的热稳定性, 失重10%时的温度高达517 ℃. 该材料具有较高的介电常数, 有望成为一种具有实际应用价值的高介电材料.

Abstract: We prepared an electroactive hyperbranched polymer containing phenyl-capped aniline tetramer segment in the chains by integration of A2+B3 strategy with oxidative coupling polymerization. The structure of hyperbranched polymer was characterized by FTIR, 1H NMR spectra, and gel permeation chromatography(GPC). A reversible electrochemical property like common oligoanilines was found. The thermal properties and dielectric properties were also investigated. With an exciting structure, reversible electrochemical properties and dielectric properties, the electroactive hyperbranched polymer would be used as electromagnetic interference(EMI) shielding and microwave absorbing materials in the future.
