Composites based on layered materials for absorption of microwaves and electromagnetic shielding

With rapid progress in science and technology, the demand for shielding has been growing day by day. In order to overcome the electromagnetic pollution, it is necessary to develop electromagnetic interference (EMI) shielding and microwave (MW) absorption materials with enhanced attenuation ability, exceptional mechanical strength, and low weight. In last few years, 2D layered materials (especially graphene-based materials, MXenes and transition metal dichalcogenides (TMDs)) with reasonable conductive nature have drawn considerable research attention. The electromagnetic absorption ability of these materials was further enhanced by their integration with other magnetic and dielectric constituents. Among various layered materials, graphene, MXenes and TMDs have been widely explored for EMI shielding applications due to their superior conductivity, high surface area, and enhanced porosity. The current review article is focused on the recent progress in shielding applications of such layered materials. A detailed illustration of the mechanisms of shielding and MW absorption is incorporated in the article. The prime roles of conductive and magnetic components on the shielding performance of the composite are systematically discussed. The review article is concluded with the future perspectives and challenges of layered materials for EMI shielding and MW absorption applications.
