Inspired by the nano/micro-scale hierarchical structure of nacre, we developed a new method for fabricating highly electrically conductive graphene-epoxy layered composites. In this new method, the graphene loading can be easily controlled, and the intrinsic three-dimensional (3-D) network of graphene in the composites results in high electrical conductivity. Through effective surface modification, the interface strength between graphene and epoxy matrix was dramatically improved, leading to the 23-fold improvement in tensile strength, 136-fold in Young’s modulus, and 8-fold in electrical conductivity compared with the pure graphene foam. These high performance bioinspired graphene-epoxy layered composites have a great potential for applications in electromagnetic interference (EMI) shielding, aerospace, and other electrical devices.
