The development of a multifunctional protective textile is still behind to supply adequate protection for the public. An international team of researchers (Hong Kong, USA – Northwestern University, US Army Aberdeen Proving Ground, the Netherlands) has designed multifunctional and regenerable N-chlorine based biocidal and detoxifying textiles using a robust zirconium metal–organic framework (MOF), UiO-66-NH2, as a chlorine carrier which can be easily coated on textile fibers. The fibrous composite exhibited rapid biocidal activity against both Gram-negative bacteria (E. coli) and Gram-positive bacteria (S. aureus) with up to a 7 log reduction within 5 min for each strain as well as a 5 log reduction of SARS-CoV-2 within 15 min. It selectively and rapidly degraded sulfur mustard and its chemical simulant 2-chloroethyl ethyl sulfide (CEES) with half-lives less than 3 minutes. The versatile MOF-based fibrous composite has the potential to serve as protective cloth against both biological and chemical threats…read more. TECHNICAL ARTICLE
