In recent years, people pay more attention to the protection against chemical warfare agents, due to the increase in the probability of usage of these chemical warfare agents in wars or terrorist attacks. In this work, MgO nanoparticles were in-situ growth on the surface of poly(m-phenylene Isophthalamide) (PMIA) forming a flexible and breathable fabric for the detoxification of mustard gas surrogate. The as-prepared nanofibrous membrane possesses a "flower-like" structure of which endows not only increase the specific surface area of the composite but also prevent the agglomeration of the MgO nanoparticles. The detoxification ability of the PMIA@MgO nanofibrous fabric was demonstrated by gas chromatography-mass spectrometer (GC-MS). It is found that after 20 h of reaction time, 70.56% of the mustard gas surrogate have been decomposed.
近年来，由于在战争或恐怖袭击中使用这些化学战剂的概率增加，人们越来越关注对化学战剂的防护。在这项工作中，MgO 纳米粒子原位生长在聚间苯二甲酰间苯二胺（PMIA）表面上，形成了一种用于解毒模拟芥子气的柔性透气织物。所制备的纳米纤维膜具有“花状”结构，不仅增加了复合材料的比表面积，而且还防止了 MgO 纳米粒子的团聚。通过气相色谱-质谱联用仪（GC-MS）证明了 PMIA@MgO 纳米纤维织物的解毒能力。结果发现，经过 20 小时的反应时间，70.56%的模拟芥子气已被分解。
