Abstract
Three-dimensional (3D) porous graphene-polymer frameworks have shown wide applications from materials science, biomaterials, tissue engineering, biomedicine, energy storage, environmental science, and other fields. In this chapter, the author summarizes recent advance (from 2015 to 2020) in the fabrication of 3D porous graphene-polymer frameworks such as films/membranes, foams, sponges, aerogels, and other structures (cake-like, honeycomb, sandwich, etc.) for electromagnetic interference (EMI) shielding applications. To achieve this aim, first the fabrication methods, such as self-assembly, hydrothermal synthesis, templated synthesis, and 3D printing, are introduced for the preparation of 3D porous frameworks, and then the tailoring of the structure, functions, and properties of 3D porous graphene-polymer frameworks by specific decoration and hybridization with various nanoscale components is demonstrated. Finally, the EMI shielding performance of the fabricated 3D porous graphene-polymer frameworks is analyzed and discussed. It is believed that this work will be helpful for readers to understand the shielding mechanisms of various 3D porous materials and to inspire the design and synthesis of novel graphene-based materials for EMI shielding.
