Abstract
An attempt has been made to study the effects of adding two different nanoparticles (NPs) namely strontium hexaferrite (SFO) and nickel cobaltite (NCO) on the physical properties of polyacrylonitrile (PAN). Nanocomposites containing PAN, and different mass contents (3, 5, 7, and 10 wt.%) of SFO and NCO NPs were prepared using the solution casting method. The nanocomposite samples were characterized by using different techniques such as field emission scanning electron microscopy (FE-SEM), Fourier transform infrared spectroscopy (FTIR), X-ray diffraction (XRD), differential scanning calorimetry (DSC), thermogravimetric analysis (TGA). The XRD spectrum for PAN shows a semicrystalline structure while the nanocomposites exhibited the peaks of the nanofillers. The FE-SEM showed a good dispersion of both SFO and NCO NPs on the surface of PAN, especially at low content. DSC data also showed that the nanocomposite samples had a broader thermic temperature range and a lower rate of evolving heat. The TGA results exhibited that with increasing the nanofiller content, the nanocomposites are more thermally stable than pure PAN
