Nowadays, along with the advances in electronic technology, electromagnetic absorption materials have attracted great attention due to their applications in the military and civil field, based on the problems of electromagnetic interference and electromagnetic compatibility.
Ferrites, as a magnetic materials, have attracted substantial attention because of low prices, environmental friendliness and sustainability, chemical stability, high magnetism saturation, and magnetic dissipation. In this research, templated BaFe12O19 nanoparticles were prepared via sol-gel method, then composited with Sr0.5La0.5MnO3 nanoparticles. then composited with graphene. Finally, templated BaFe12O19/Sr0.5La0.5MnO3/GO nanocomposites were blended in the silicone rubber matrix and then molded to investigate their microwave absorption properties at x-band frequency. Templated nanoparticles and the as prepared nanocomposite were characterized by Fourier transform infrared (FT-IR),field emission scanning electron microscopy (FE-SEM), X-ray diffraction (XRD), and microwave absorption characteristics were obtained by vector network analyzer (VNA).using magnetic and electrical compounds toghether, caused to increase absorption.
Key words: Microwave absorption, Nanocomposite, Magnetic nanomaterial, BaFe12O19, Sr0.5La0.5MnO3, grapheme.
