Synthesis and Properties of Films of a Polyimide Filled with Ferromagnetic Nanoparticles

摘要

Film-forming polyimide nanocomposites containing 5 to 20 wt % nanoparticles were prepared from ferromagnetic Fe/Fe_3O_4 nanoparticles and a polyimide derived from 4,4'-bis(4-aminophenoxy)diphenyl sulfone and 1,3-bis(3,4-dicarboxyphenoxy)benzene dianhydride. The mechanical properties and magnetization of the nanocomposite samples were studied in relation to the nanoparticle concentration.
