Abstract There is a significant increase in the demand for lightweight and compressible electromagnetic interference (EMI) shielding materials various fields. Though MXene aerogels hold immense potential as EMI materials, several shortcomings including poor water resistance, low mechanical robustness, easy oxidation, high cost limits of their wide application. This work reported novel strategy involving co‐assembly cellulose nanofibers (CNF) through directional freezing freeze‐drying, followed by capsulation‐concreting thin layer flame‐retardant polydimethylsiloxane (PDMS) onto aerogel, to multi‐hierarchically construct series high‐performance CNF/MXene/PDMS composite aerogels. The CNF/MXene/PDMS/MPP‐Zr@PDA aerogel achieved ultrahigh effectiveness 96.8 dB (X‐band) utilization efficiency 1713.27 g −1 . Furthermore, PDMS coating effectively imparted excellent compressibility durability 3D scaffold, resulting compressive strength 17.01 kPa representing 199.5% compared CNF aerogel. Additionally, exhibited outstanding properties (54.6% reduction heat release rate), ultralow thermal conductivity 0.0530 W m K hydrophobicity. Therefore, durable promising applications protection, management, smart fire detection, other specific
