Protective Fabrics: Metal-Organic Framework Textiles for Rapid Photocatalytic Sulfur Mustard Simulant Detoxification

Chemical targets to deactivate biological and chemical toxins using surfaces and fabrics

“…We previously mentioned the examples that prove the concept of textiles as detoxication materials, such as indoor air-purifying curtains. Similar studies have been conducted on CWA simulants and have shown that catalysts integrated into fabric are more effective than their isolated powder form 94 . These results have been corroborated by the study of Al–porphyrin-based MOF (Al-PMOF) powder and Al-PMOF integrated into polypropylene (PP) fibre composite (PP@Al-PMOF) for the photo-oxidation of CEES under O 2 and LED irradiation.…”

“…These results have been corroborated by the study of Al–porphyrin-based MOF (Al-PMOF) powder and Al-PMOF integrated into polypropylene (PP) fibre composite (PP@Al-PMOF) for the photo-oxidation of CEES under O 2 and LED irradiation. MOFs’ linkers containing photosensitive groups were used to achieve a fast degradation of CEES, with t 1/2 of 16 and 4 min for the powder form and PP@Al–PMOF, respectively 94 . CEES was degraded only under irradiation, which indicates that such technology could be promising if integrated in everyday textiles for the detoxification of the surrounding environment from CWAs.…”

Doubly Protective MOF‐Photo‐Fabrics: Facile Template‐Free Synthesis of PCN‐222‐Textiles Enables Rapid Hydrolysis, Photo‐Hydrolysis and Selective Oxidation of Multiple Chemical Warfare Agents and Simulants

“…For example, to protect military and civilians against potential CWA threats, there is critical need for catalytically active composites that can be deployed in engineered clothing, field‐shelters, surface decontamination towels, sensors, wound dressings and other PPE [5, 32, 33] . These and related needs will benefit from new synthesis methods for MOF‐fabric composites employing simple, safe, and chemically mild procedures such as electrospinning, direct solvothermal growth, spray‐coating, or adhesives [22, 30, 42–44, 34–41] …”

“…[5,32,33] These and related needs will benefit from new synthesis methods for MOF-fabric composites employing simple, safe, and chemically mild procedures such as electrospinning, direct solvothermal growth, spray-coating,o ra dhesives. [22,30,[42][43][44][34][35][36][37][38][39][40][41] For any protective garment using MOF-fabrics, the safety of the fabric itself will be an important concern. While there are only af ew reports regarding MOF safety, [45,46] toxicityi se xpected to depend on MOF crystal size, composition, and stability, with the smallest crystals (< 100 nm) of primary concern.…”

Capture of Sulfur Mustard by Pillar[5]arene: From Host-Guest Complexation to Efficient Adsorption Using Nonporous Adaptive Crystals

“…Recently, the adsorption and photocatalytic oxidation of SM simulants by MOFs have been well demonstrated ( Ma et al., 2019 ; Cao et al., 2019 ; Lee et al., 2020 ; Giannakoudakis and Bandosz, 2020 ). The present system based on organic macrocycles has the following characteristics (the advantages of pillar[5]arene over MOF are summarized in Table S1 ): (1) easy accessibility: EtP5 can be prepared through a single-step reaction in high yield of more than 70%, and all reagents are cheap and commercially available; (2) good stability: crystalline materials of EtP5 are stable to moisture; (3) high complexation ability and adsorption stability: SM and its simulants can be quantitatively prisoned in pillar[5]arene containers for quite a long time; (4) convenient modification: mono-, di-, tetra-, and per-substituted pillar[5]arenes can be conveniently obtained.…”
