Synthesis and electromagnetic property of Li0.35Zn0.3Fe2.35O4 grafted with polyaniline fibers
چکیده انگلیسی
Li0.35Zn0.3Fe2.35O4 (LZFO) grafted with polyaniline (PANI) fibers was synthesized by in-situ polymerization. FTIR, XRD, SEM and electromagnetic characterization were used to investigate chemical composition, micro-morphology, electromagnetic properties and microwave absorbing properties of the composite. The results show that PANI fibers were grafted on the surfaces of LZFO particles. The reflection loss exceeds 10 dB in the frequency range from 2.5 to 5 GHz and from 15 to 17 GHz, and the maximum reflection loss reaches −33 dB at 15.9 GHz. The enhanced microwave absorption properties of the LZFO/PANI-fiber composites are mainly ascribed to the combined effect of the dielectric and magnetic loss and the improved impedance matching.
