Generally, detoxification fabrics are defined as fabrics that remove or inhibit the production of toxic compounds, especially chemical warfare agents such as nerve gas agents. They are usually prepared using a complicated and time-consuming method. This study suggests a facile treatment method for preparing detoxification fabrics against nerve gas agents using polyethyleneimine and microwave curing. The detoxification properties of polyethyleneimine and microwave-treated polypropylene nonwoven fabric were evaluated using diisopropylfluoro-phosphate, which is a nerve agent simulant. The treated polypropylene fabric decontaminated 53.6% of diisopropylfluorophosphate (DFP) in 2 h at 32 °C, and the half-life of DFP on the surface of the treated fabric was 122 min. The result indicates that the treated fabric can act as a basic organocatalyst for the DFP hydrolysis and has a shorter half-life owing to the large number of amine groups. Therefore, the facile treatment method has the potential for use in the preparation of detoxification fabrics.
一般来说,解毒织物被定义为能够去除或抑制有毒化合物产生的织物,尤其是诸如神经毒气剂等化学战剂。它们通常采用复杂且耗时的方法制备。本研究提出了一种使用聚乙烯亚胺和微波固化来制备针对神经毒气剂的解毒织物的简便处理方法。使用作为神经毒剂模拟物的二异丙基氟磷酸酯评估了聚乙烯亚胺和微波处理的聚丙烯无纺布的解毒性能。经处理的聚丙烯织物在32℃下2小时内对二异丙基氟磷酸酯(DFP)的去污率为53.6%,且DFP在经处理织物表面的半衰期为122分钟。结果表明,经处理的织物可作为DFP水解的碱性有机催化剂,并且由于大量胺基的存在而具有较短的半衰期。因此,这种简便的处理方法具有用于制备解毒织物的潜力。
