Abstract
• MOF-808/fiber composite was fabricated using tannic acid (TA) hybrid coating as the mediating layer. • The as-prepared MOF-808/fiber composite with 23.4 % MOF-808 displayed a high surface area (340 m 2 /g). • The obtained PP fabrics displayed a half-life of 1.3 min for dimethyl p -nitrophenyl phosphate (DMNP) degradation. • The PP@TA-APTES@MOF-808 catalyst has good stability for DMNP detoxification . Zirconium-based metal-organic frameworks (Zr-MOFs) have emerged as promising candidates for the catalyzed hydrolysis of nerve agents, but facile methods for their integration into textiles are still lacking. Herein, we report a strategy for the preparation of MOF-808-loaded polypropylene (PP) nonwoven fabrics mediated by a tannic acid (TA) and 3-aminopropyltriethoxysilane (APTES) hybrid coating (TA-APTES). The as-prepared PP nonwoven fabric displayed a rapid catalytic degradation rate for dimethyl p -nitrophenyl phosphate (DMNP) with a half-life of 1.3 min in a basic buffered condition.
