摘　　要：以十六烷基三甲基溴化铵(CTAB)胶束作为软模版,过硫酸铵(APS)为氧化剂制备纳米纤状聚吡咯(C-PPy)导电聚合物;利用电子转移再生催化剂原子转移自由基聚合(ARGET-ATRP)法合成羟基丙烯酸酯氟树脂,对其结构、形貌进行表征。将C-PPy与氟化丙烯酸酯树脂、固化剂复合,制成复合导电涂料,测试涂层力学性能与导电性能。实验结果表明:当C-PPy用量占涂料体系的质量分数为15%时,复合涂层的耐冲击性提高约133%,导电性能达到0.006 S/cm,涂层综合性能优异。The nanofibre-based C-PPy was synthesized by using cetyhrimethylammonium bromide （CTAB） micelles as soft matrix and ammonium persulfate （APS） as oxidant. The hydroxylacrylate fluororesin was synthesized via activators generated by electron transfer-atom transfer radical polymerization （ARGET-ATRP） , and its structure and morphology were characterized by SEM, XRD and ATR-FTIR. The nanofibre-based C-PPy was blended with fluor- inated acrylate and curing agent to give composite conductive coatings. The mechanical and conductive properties of the cured film were investigated. The results indicated that a composite conductive coatings composition comprising the nanofibre-based C-PPy 15% could show good comprehensive properties including impact resistance increased by 133% and conductivitv 0. 006 S/cm.
