中文摘要：

导电高分子聚苯胺由于其优异的电学性能而备受关注一．但由于聚苯胺分子链上缺陷较多，结构不规整，影响了对其导电机制的深入研究；由于其不溶不熔，可加工性差，阻碍了其实际应用．因此，设计并合成结构完整确定的含有苯胺链段的聚合物备受关注．

英文摘要：

A new electroactive polyaryletherketone containing benzonitrile（EPEEK-CN） was synthesized from 2,6-difluorobenzonitrile,p-benzenediol and difluoromonomer containing phenyl-capped aniline tetramer segment,via ternary polycondensation.The obtained EPEEK-CN shows certain extent solubility in organic solvents,and its film casted from DMAc solution exhibits interesting electrical,mechanical and dielectric properties.
