Abstract

<abstract abstract-type="main"> <title> <x xml:space="preserve">Abstract</x> </title> <p>In this study, the novel polyarylene ether nitrile containing carboxyl groups (CPEN)/Fe₃O₄ hybrids were synthesized via the solvent‐thermal route. The SEM and TEM images showed that the surface of functionalized Fe₃O₄ hybrids (CPEN‐<italic>f</italic>‐Fe₃O₄) became rough and coated with a thin polymer layer successfully. Chemical bonds were formed between the carboxyl groups and Fe₃O₄ spheres, which were characterized by FTIR and XRD. Series of PEN composite films were prepared through solution‐casting method with different contents of CPEN‐<italic>f</italic>‐Fe₃O₄ hybrids and raw Fe₃O₄ spheres. The SEM images showed that the CPEN‐<italic>f</italic>‐Fe₃O₄ hybrids became much more dispersible and compatible in PEN matrix than that of raw Fe₃O₄ spheres, which was further confirmed by rheological study. The magnetic analysis showed that the saturation magnetization of composites films increased with the increase of CPEN‐<italic>f</italic>‐Fe₃O₄ hybrids loading content. The results of thermogravimetric and mechanical study exhibited that the composite films had good thermal stability and mechanical property. POLYM.
