Diverse innovative fabrics with specific functionalities have been developed for requirements such as self-decontamination of chemical/biological pollutants and toxic nerve agents. In this work, Zr(OH) -coated nylon-6,6 nanofiber mats were fabricated for the decontamination of nerve agents. Nylon-6,6 fabric was prepared via the electrospinning process, followed by coating with Zr(OH) , which was obtained by the hydrolysis of Zr(OBu) by a sol-gel reaction on nanofiber surfaces. The reaction conditions were optimized by varying the amounts of Zr(OBu) ,the reaction time, and the temperature of the sol-gel reaction. The composite nanofibers show high decontamination efficiency against diisopropylfluorophosphate, which is a nerve agent analogue, due to its high nucleophilicity that aids in the catalysis of the hydrolysis of the phosphonate ester bonds. Composite nanofiber mats have a large potential and can be applied in specific fields such as military and medical markets.
为满足对化学/生物污染物和有毒神经毒剂进行自净化等需求,已研发出具有特定功能的多种创新型织物。在这项工作中,制备了用于神经毒剂净化的Zr(OH)包覆尼龙-6,6纳米纤维毡。尼龙-6,6织物通过静电纺丝工艺制备,随后在纳米纤维表面通过溶胶-凝胶反应由Zr(OBu)水解得到的Zr(OH)进行包覆。通过改变Zr(OBu)的用量、反应时间和溶胶-凝胶反应温度对反应条件进行了优化。由于复合纳米纤维具有高亲核性,有助于催化膦酸酯键的水解,因此对神经毒剂类似物二异丙基氟磷酸酯表现出高净化效率。复合纳米纤维毡具有很大的潜力,可应用于军事和医疗市场等特定领域。
