Ferrite-manganese oxide-MXene composite wave-absorbing particle as well as preparation method and application thereof
The invention discloses ferrite-manganese oxide-MXene composite wave-absorbing particles as well as a preparation method and application thereof. The ferrite-manganese oxide-MXene composite wave-absorbing particle disclosed by the invention comprises a ferrite inner core, a manganese oxide middle shell layer and an MXene outer coating layer. The preparation method of the ferrite-manganese oxide-MXene composite wave-absorbing particles comprises the following steps: 1) preparing ferrite nanoparticles and an MXene aqueous dispersion; 2) preparing ferrite-manganese oxide core-shell particles; 3) preparing surface modified ferrite-manganese oxide core-shell particles; and (4) compounding the surface modified ferrite-manganese oxide core-shell particles and MXene. The ferrite-manganese oxide-MXene composite wave-absorbing particle has the advantages of excellent electromagnetic wave absorption performance, wide absorption frequency band, good impedance matching property, light weight and simple preparation method, and is suitable for large-scale industrial application..
