Abstract

There is an enormous scope for graphene and its analogues in electromagnetic interference (EMI) applications, especially as microwave absorbers. Recent studies have shown that graphene analogues exhibit excellent electromagnetic shielding through uniquely designed 3D macroporous foams or as ultrathin papers and thus, are inevitable towards developing hybrid architectures. Herein, we provide a comprehensive evaluation of the key structural and mechanistic attributes of both graphene-based foams and papers towards EM shielding applications. Furthermore, we emphasize on the crucial aspect of architecture and alignment of graphene in both foam and paper towards enhancing EMI shielding for emerging applications.
