Abstract
Ni0.2Mn0.4Zn0.4Fe2O4 (NMZF) nanoparticles were anchored on the surface of MXene(Ti3C2Tx) to form Ti3C2Tx/NMZF nanocomposites for optimization of microwave absorption performance. The Ti3C2Tx/NMZF nanocomposites were synthesized by using a four-step strategy, including sonication, stirring, hydrothermal reduction and vacuum drying. More than 40 percent of the NMZF nanoparticles in this nanocomposite were assembled to form a conductive network. Meanwhile, the multilayer MXene acted as a framework to host the NMZF nanoparticles, providing dipolar polarization, interfacial polarization and eddy current loss. Benefiting from the structure design of MXene, combined with magnetic materials and optimized impedance matching, the Ti3C2Tx/NMZF exhibited a minimum reflection loss (RLmin) of −57.39 dB, with a thickness of 2.97 mm and an effective absorption bandwidth (EAB) of 3.2 GHz. Therefore, such a facile method could be used to construct nanocomposites with microwave absorption performance (-57.39 dB, 3.2 GHz), so as to address microwave pollution issues.
