Abstract
Metal-organic frameworks (MOFs) have a strong ability to consume electromagnetic (EM) wave due to their rich porous structure and large specific surface area. In this work, multi-layer ZIF-67/graphite nanosheets (ZIF-67/GNs) were successfully obtained through uniform stirring and aging process. Co3O4/GNs composites with layered structures and porous structures were obtained by calcining at different temperatures. Obviously, the calcination temperature has a significant effect on the EM absorption performance. Dielectric loss, magnetic loss, and good impedance matching make a significant contribution to enhancing EM wave absorption capacity of Co3O4/GNs composites. When the calcination temperature is 350 ° C, the composites show the best EM wave absorption performance, the RLmin value is −52.46 dB with 3.4 mm. It is worth noting that the Co3O4/GNs composites can be expected to have strong absorption intensity, and the selectable bandwidth width will ensure that it is an attractive EM wave absorbing material.
