Hierarchical Cellulose/MXene Aerogel Films with Coral‐Like Polyaniline Skin for Absorption‐Led Broadband EMI Shielding (Adv. Funct. Mater. 31/2026)

EMI Shielding In their Research Article (10.1002/adfm.74562), Ting Xu, Chuanling Si, Xuejun Pan, and co-workers show that hierarchical cellulose/MXene aerogel films with a coral-like polyaniline skin achieve lightweight, flexible, and absorption-dominant electromagnetic interference shielding. The porous skin–core architecture enhances wave penetration, multiple internal reflections, interfacial polarization, and conductive loss, thereby enabling efficient broadband attenuation while maintaining low density, mechanical robustness, and structural stability under practical conditions.
