Description
Summary:A variety of electromagnetic wave absorption materials (EMWAs) have been reported, but the integration of powder materials and multifunctional devices should be investigated in-depth to adapt to practical demands. Herein, carbon-coated cobalt composites were prepared by adsorbing magnetic metal cations into an anionic crystalline framework through an electrostatic encapsulate process. Excellent reflection loss (RL min ) of −40.49 dB and effective absorption bandwidth (EAB) of 5.36 GHz (RL
