Preparation and characterization of poly(acrylonitrile-co-acrylic acid) nanofibrous composites with Fe_3O_4 magnetic nanoparticles

摘要

Nanofibrous composites are a new class of polymer materials with controlled and tailored properties. Novel Fe_3O_4/poly(acrylonitrile-co-acrylic acid) nanofibrous composites with magnetic behavior have been prepared by a simple electrospinning process. The nanofibrous composites were characterized by X-ray diffraction, field emission scanning electron microscopy and vibrating sample magnetometer. The distribution of Fe_3O_4 nanoparticles inside the nanofibrous composites was investigated by field emission scanning electron microscopy. X-ray diffraction revealed the presence of Fe_3O_4 nanoparticles in the nanofibrous composites. The maximum saturation magnetization for the composites, measured at 300 K, was 30.51 emu/g.
