Multiscale Manufacturing of Recyclable Polyimide Composite Aerogels (Adv. Mater. 5/2025)

Recyclable Polyimide Composite Aerogels In article number 2411599 by Wim J. Malfait, Qinghua Zhang, Shanyu Zhao, and co-workers, a molecular design strategy was employed to facilitate the formation and controlled disassembly of high-performance, recyclable polyimide composite aerogels. The innovative “aerogel-in”aerogel" structure exhibits a highly porous, interpenetrating architecture with complete disaggregation capabilities. This composite showcases exceptional resistance to extreme conditions, spanning from ultra-low temperatures of −196 °C to ultra-high environments of 800 °C, providing a groundbreaking and sustainable solution for next-generation thermal protection materials.
