Abstract:

To address the issues of polyaniline(PANI) aggregation and thermal degradation in conventional melt-blended polyetheretherketone(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 was prepared by varying the molar ratio of the key monomers, N-phenyl(4,4′-difluorodiphenyl) ketone-amine(PDK) and 4,4′-difluorodiphenyl ketone. These precursors were subsequently converted into PEEK/PANI composite films through side-chain hydrolysis and oxidative coupling. The results showed that the composite film with a 9/1 monomer ratio(denoted as PEEK/PANI-0.9) exhibited the best overall performance. Scanning electron microscopy(SEM) characterization revealed a dense and uniform surface morphology without obvious pores. Electrically, a 40 μm-thick PEEK/PANI-0.9 film achieved a conductivity of 4.78×10-⁴ S/m. In summary, this method successfully produces PEEK films with well-dispersed, high content PANI, showing promise for applications in areas requiring conductivity, antistatic protection, electromagnetic shielding and wave absorption.
