Porifera‐Inspired Lightweight, Thin, Wrinkle‐Resistance, and Multifunctional MXene Foam

Abstract Transition metal carbides/nitrides (MXenes) demonstrate a massive potential in constructing lightweight, multifunctional wearable electromagnetic interference (EMI) shields for application in various fields. Nevertheless, it remains challenging to develop a facile, scalable approach to prepare the MXene‐based macrostructures characterized by low density, low thickness, high mechanical flexibility, and high EMI SE at the same time. Herein, the ultrathin MXene/reduced graphene oxide (rGO)/Ag foams with a porifera‐inspired hierarchically porous microstructure are prepared by combining Zn 2+ diffusion induction and hard template methods. The hierarchical porosity, which includes a mesoporous skeleton and…
