Graphene has attracted much attention in fields such as physics, chemistry, and materials science, because of its unique structure and excellent properties. Graphene can be used as microwave absorption materials due to its large specific surface area, low density, good conductivity, high temperature resistance and oxidation resistance, which can enhance the microwave absorbing properties and reduce the materials’ density to obtain microwave absorbing materials with light weight and high performance. In this paper, the applications of graphene-based composites in microwave absorption field in our group were summarized.
