▎ 摘  要

Chemical warfare agents (CWAs) are significant threats to human peace and global safety. Most of the personal protective equipment in service used to barrier CWAs is devoid of decontamination activity. Rechargeable N-halamine-based detoxifying nanofibers/graphene chemical protective aerogels (HNAs) with ternary pores bearing pi-conjugation galleries that can effectively capture mustard gas through halogen bonds and convert them into the nontoxic products are proposed. Microporous nanofibers together with graphene construct a robust lamellar conjugated system dominated by pi-pi interactions, providing interconnected channels for rapid dispersion and diffusion of contaminated fluid. The resulting HNAs exhibit integrated performances of low density, hierarchical porosity, a speedy recovery after a significant deformation, rechargeable vesicants decontamination (half-life of 1.52 min), and low filtration resistance. The successful fabrication of the intriguing materials provides new insights into the generation of reliable, rechargeable, structurally adaptable, and long-term usable real-time detoxifying adsorbents for chemical personal protective equipment application.
