چکیده مقاله:

Magnetic nanoparticles(MNPs) polymer composite nanofibers were successfully obtained through electrospinning of polyacrylic acid(PAA) polyvinyl alcohol(PVA) aqueous solutions with homogenously dispersed magnetite Fe3O4 nanoparticles (MNPs). Poly(vinyl alcohol) (PVA) and poly(acrylic acid) (PAA) were chosen as the polymer components. The distribution of MNPs inside the composite nanofibrous was investigated by field emission scanning electron microscopy(SEM) and transmission electron microscopy(TEM). Experiment results showed that the diameters of MNPs were in a range of 15 nm to 65 nm under all of our synthesis conditions; and MNPs can homogenously disperse in PVA composite nanofibers when they were stabilized by PAA. X-ray diffraction reveals the presence of Fe3O4 nanoparticles in the composite nanofiber. In addition, the water resistance of MNPs PAA PVA composite nanofibers was dramatically enhanced by heat treatment. The effect of water immersion experiments of the nanofibrous mats were performed for the study of its solvent stability. The results show that the prepared composite nanofibrous mats exhibit remarkable water resistance. Therefore, in our process to preparing magnetic MNPs PVA composite nanofibers.
