Nature‐Inspired Functional Aerogel Fibers with Engineerable Core–Shell Morphology (Adv. Mater. Technol. 1/2026)

Functional Aerogel Fibers In their Research Article (10.1002/admt.202501315), Mohammad Arjmand and co-workers report the synthesis of nature-inspired core–shell aerogel fibers using coaxial wet spinning, featuring a polyimide shell encapsulating a Ti3C2Tx MXene core. By optimizing the solvent-exchange process, they achieve hierarchical porosity, resulting in moisture-resistant, knittable, and flame-retardant fibers with a tensile strength of 20.4 MPa and an absorption-dominant electromagnetic interference shielding effectiveness of 54.9 dB.
