Abstract

In this study the substituted Strontium hexaferrite with formula SrFe11. 1(ZrZn0. 5Co0. 5)0. 45O19 was firstly synthesized by a sol-gel auto combustion method. Then the ternary nanocomposite of Polyaniline/ SrFe11. 1(ZrZn0. 5Co0. 5)0. 45O19/Multiwalled carbon nanotubes ( MWCNTs) was prepared by insitu polymerization method. The structure and surface morphology of substituted hexaferrite, and nanocomposite were investigated by using X-ray diffractometer ( XRD), Fourier transform infrared spectroscopy ( FTIR), and field emission scanning electron microscope ( FESEM). The results showed that the substituted hexaferrite and Multiwalled carbon nanotubes were effectively coated by Polyaniline chains. The magnetic properties of samples were measured by the vibrating sample magnetometer ( VSM). The measured magnetic values decreased from (Ms=60 emu/g, Mr=30emu/g) for substituted hexaferrite, to ( Ms=11. 5emu/g, Mr=6emu/g) for nanocomposite. The microwave absorption properties of samples were determined by vector network analyzer ( VNA). The results indicated that the minimum reflection loss value of the nanocomposite is-30 dB at 10. 1 GHz with appropriate bandwidth in the range of X-band. The reflection loss measurements demonstrated that the nanocomposite has good potential as a Microwave absorbent.
