Structure and properties of the MXene/CNF hybrid aerogels with various CNF contents. Microstructures of the MXene/CNF hybrid aerogels with a) 17 wt% and b) pure MXene aerogels, at densities of 4 mg cm^–3. c) Optical images of the MXene‐based hybrid aerogels, showing large‐area MXene/CNF aerogels (12 × 6 cm²) with various CNF contents (from top to bottom, corresponding to the pure CNF aerogels, the MXene/CNF with 50 wt% CNF, and MXene/CNF with 17 wt% CNF) at a density of 4 mg cm^–3, and an image demonstrating the flexible performance of the MXene/CNF aerogels with 17 wt% CNF. d) Electrical conductivity and compressive modulus of the MXene‐based aerogels (4 mg cm^–3) with various CNF contents. e) EMI SE in the X‐band and f) shielding performance at 10 GHz of the MXene‐based hybrid aerogels (4.0 mg cm^–3) with various CNF contents.
