Progress in graphene-based magnetic hybrids towards highly efficiency for microwave absorption

Abstract

• Graphene-based magnetic microwave absorption materials (MAMs) is classified according to their components including magnetic metal, multiple alloy and metal-free hybrids. • Special structural features and regulation strategies of graphene-based magnetic MAMs are introduced. • Challenges and prospects based on graphene-based magnetic MAMs are prospected. Nowadays, the yearning for microwave absorption materials (MAMs) are more and more urgent for dealing with the increasingly serious electromagnetic pollution and the demand of modern military security. Among potential candidates, the graphene (GE) based magnetic hybrids have advantages in structural controllable and designing flexibility, providing opportunities for achieving highly efficiency of microwave absorption (MA). Thus, the structural regulation and MA performances of GE-based magnetic hybrids arouse great attention in related fields. In this review, we summarize the recently progress in MA performance of GE-based magnetic hybrids. Typical absorption process and corresponding mechanism are firstly introduced, for guiding the design of GE-based magnetic MAMs. Then, the magnetic components, synthesis methods, structural features and regulation strategies of these GE-related magnetic materials are reviewed, and their influences on MA performances have also been discussed. Challenges, and prospects of the GE-based magnetic MAMs are suggested. This review provides a brief but systematic introduction to GE-based magnetic MAMs, which may pave the way for the design of MAMs with highly efficient MA performances.
