摘要：

Novel magnetic Fe3O4/polyphosphazene nanofibers were successfully prepared via a facile approach by ultrasonic irradiation. The structure and morphology were characterized by SEM, TEM, EDX, IR and XRD. The characterization results show that the magnetic Fe3O4/polyphosphazene nanofibers are several microns in length and 50-100 nm in diameter with Fe3O4 nanoparticles of 5-10 nm attached on the surface. The interaction between Fe3O4 nanoparticles and polyphosphazene nanofibers was thought as coordination behavior. TG curves show that the magnetic Fe3O4/polyphosphazene nanofibers have good thermostability and high magnetism content of about 44%. Magnetic studies show that the magnetic nanofibers exhibit good superparamagnetic properties with high magnetization saturation value of about 36 emu/g. (C) 2009 Elsevier Masson SAS.
