Abstract
Eelectromagnetic pollution has become an increasingly prominent problem and electromagnetic wave absorbing materials have received widespread attention. Metal organic frameworks (MOFs) derived materials work as wave absorbing materials having the advantages of simple synthesis process, low production cost, high specific surface area and porosity, good thermal stability, and also have excellent impedance matching and various attenuation mechanisms, which have been widely studied in the field of electromagnetic wave absorption. In here, the classification and preparation methods of MOFs are summarized, their wave absorption mechanisms are analyzed. It also details the current research progress and analyses their advantages and disadvantages from the perspectives of monometallic MOF, multi-metallic MOF and wave absorbing materials derived from MOF compounded with other materials (including carbon materials, MXene and conductive polymers). This article aims to illustrate the application of MOFs and their derived composites in the research of electromagnetic wave absorption, and hopes to offer a reference for the further research based on these promising materials.
This paper describes the application of MOFs and their derived composites in electromagnetic wave absorption research. [Display omitted]
