Review and Perspective of Tailorable Metal-Organic Framework for Enhancing Microwave Absorption

Metal-organic frameworks(MOFs)and their pyrolytic derivates,displaying diverse chemical compositions and microstructures,pro-vide the infinite potential for preparing high-performance microwave absorption materials(MAMs)and have attracted extensive at-tention.In this review,we systematically reviewed the recent progress of MOF-based MAMs,including three types of MOF-based MAMs(MOF-derived metal/carbon nanocomposites,MOF-based hybridization materials and conductive MOF).Besides that,the microwave absorption properties and their related physical and chemical appearance were also analyzed.On behalf of synergistic effects between microstructures,dielectric components and magnetic response,the MOF-based MAMs show excellent microwave absorption performance,which is superior to that of traditional single metal,metal alloy and pure carbon-based MAMs.Further-more,the novel conductive MOF with tunable electrical conductivity shows great potential in MAMs due to the fact that it can dra-matically simplify the synthesis process.
