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.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, ^1 H 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 proper- ties and dielectric properties, the electroactive hyperbranched polymer would be used as electromagnetic inter- ference（EMI） shielding and microwave absorbing materials in the future.
