Since the emergence of chemical, biological, radiological, and nuclear risks, significant efforts have been made to create efficient personal protection equipment. Recently, metal-organic framework (MOF) materials have emerged as new promising candidates for the capture and degradation of various threats, like chemical warfare agents (CWAs) or radioactive species. Herein, we report a new synthesis method of MOF-textile composites by microwave irradiation, with direct anchoring of MOFs on textiles. The resistance of the composite has been tested using normed abrasion measurements, and non-stable samples were optimized. The protection capacity of the MOF-textile composite has been tested against dimethyl 4-nitrophenyl phosphate, a common CWA simulant, showing short degradation half-life (30 min). Radiological/nuclear protection has also been tested through uranium uptake (up to 15 mg g adsorbent) and the capture of Kr or Xe gas at 0.9 and 2.9 cm/g, respectively.
自化学、生物、放射和核风险出现以来,人们为制造高效的个人防护装备付出了巨大努力。最近,金属有机框架(MOF)材料已成为捕获和降解各种威胁(如化学战剂(CWA)或放射性物质)的新的有前景的候选材料。在此,我们报告了一种通过微波辐射直接将MOF锚定在纺织品上来合成MOF-纺织品复合材料的新方法。使用标准磨损测量对复合材料的抗性进行了测试,并对不稳定的样品进行了优化。MOF-纺织品复合材料对常见的CWA模拟物磷酸二甲基4-硝基苯酯的防护能力进行了测试,其降解半衰期较短(30分钟)。还通过铀吸收(高达15 mg/g吸附剂)以及分别在0.9和2.9 cm/g下捕获氪气或氙气对放射/核防护进行了测试。
