Tailorable MOF architectures for high-efficiency electromagnetic functions

Abstract

The advent of 5G and 6G eras switches on intelligent life and information revolution. Unfortunately, the resulting electromagnetic radiation would harm human health and current automation systems. Hence, the worldwide demand for novel and efficient electromagnetic functional materials has been growing dramatically. Metal–organic frameworks (MOFs), which possess diverse structures and components, have inspired infinite passion and creativity of researchers in the electromagnetic field. Herein, the recent progress in synthesis of MOF architectures is discussed. Then, the attenuation mechanism of electromagnetic waves inside MOF architectures is revealed, and the development of highly efficient MOF-based microwave absorption and shielding materials with tunable electromagnetic properties is presented. Finally, the current challenges and possible future research directions are dissected, which provides guidance for fabricating MOF-based electromagnetic functional materials.
