Abstract

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.
