Abstract

In this work, we present the recent study in the microwave absorption performances of the Cu0.5Ni0.5Fe2O4@polyaniline (CNF@PANI). This material has been synthesized by polymerization and hydrothermal reaction process. The PANI fiber structure with the whole cover of CNF nanoparticles could establish the improvement of microwave absorption performances. The value of optimal reflection loss reached -60.9 dB at 12.9 GHz with the sample which had thicknesses of 2.5 mm and the widest effective bandwidth is up to 6.1 GHz with the sample which had thicknesses of 2.0 mm. By varying the thickness within the range of 2.0 to 3.5 mm, this effective bandwidth will cover the entire X and Ku bands.
