Recent advancement of magnetic MOF composites in microwave absorption

Abstract

Nowadays, electronic equipment has brought great convenience to people. However, the electromagnetic microwave it generates also brings adverse effects. It is generally hoped to prepare electromagnetic microwave absorption materials with the characteristics of light and thin, wide absorption band and strong absorption performance. Recently, the metal organic framework (MOF) has been regarded as an ideal material. Usually, the combination of magnetic metal and MOF can improve the magnetic loss performance of the material and make the material have a wider application. This paper analyzes and summarizes the latest development of magnetic MOF microwave absorption materials thoroughly, including the classification of magnetic MOF microwave absorption materials, microwave absorption mechanism, design principle and preparation methods. Finally, the development of magnetic MOF microwave absorption materials and the challenges faced in the development process are reasonably prospected, which provides a reference for the development of magnetic MOF microwave absorption materials.
