摘要： 为解决常规熔融共混法制备聚醚醚酮/聚苯胺（PEEK/PANI）复合材料过程中存在的聚苯胺（PANI）易团聚和高温分解的问题，本研究采用聚合物前驱体膜一步原位合成法，成功制备出高含量且分布均匀的聚醚醚酮/聚苯胺复合薄膜。通过考察前驱体聚合物的共聚组成对最终PANI含量及薄膜性能的影响，调控关键单体N-苯基（4,4′-二氟二苯）酮胺和4,4′-二氟二苯甲酮的摩尔比，制备了一系列聚芳醚亚胺（PAEN）共聚物薄膜作为前驱体膜，并对其经侧基水解协同氧化偶联反应得到的PEEK/PANI复合薄膜进行了细致表征。测试结果表明，当N-苯基（4,4′-二氟二苯）酮胺和4,4′-二氟二苯甲酮的摩尔比为9∶1（记为PEEK/PANI-0.9）时，薄膜表现出最佳综合性能。扫描电子显微镜（SEM）观察显示，PEEK/PANI薄膜表面致密均匀、无明显孔洞。电学测试表明，厚度为40 μm的PEEK/PANI-0.9薄膜的电导率较高，为4.78×10?? S·m?1。综上本工作制备出PANI含量高、分散均匀的聚醚醚酮导电复合薄膜，未来有望在导电、抗静电、电磁屏蔽及吸波领域得到广泛应用。 关键词 一步原位合成法；导电材料；聚醚醚酮；聚苯胺

Abstract: To address the issues of polyaniline (PANI) aggregation and thermal degradation in conventional melt-blended PEEK/PANI composites, we developed a one-step in-situ synthesis method starting from copolymer precursor films. A series of precursor films based on PAEN copolymer were prepared by varying the molar ratio of the key monomers, N-phenyl (4,4′-difluorodiphenyl) ketone-amine and 4,4′-difluorodiphenyl ketone. These precursors were subsequently converted into PEEK/PANI composite films through side-chain hydrolysis and oxidative coupling. The composite film with a 9:1 monomer ratio (denoted as PEEK/PANI-0.9) exhibited the best overall performance. Scanning electron microscopy (SEM) revealed a dense and uniform surface morphology without obvious pores. Electrically, a 40 μm-thick PEEK/PANI-0.9 film achieved a conductivity of 4.78×10?? S·m?1. In summary, this method successfully produces PEEK films with well-dispersed, rich PANI content, showing promise for applications in areas requiring conductivity, antistatic protection, electromagnetic shielding, and wave absorption.
