摘　　要：为实现对芥子气模拟物去污,开发柔性防护织物。利用磷酸处理对芳纶纳米纤维(ANFs)表面改性,利用水热法实现MOF-808在ANFs表面的原位生长,利用冰模板技术制备MOF-808@ANF气凝胶材料,研究MOF-808的负载量对其结构和对芥子气模拟物2-氯乙基乙基硫醚(CEES)降解性能的影响。结果表明:MOF-808负载量可达125.56%,比表面可达408.267 m^(2)/g,MOF-808@ANF气凝胶对CEES具有良好的降解效果,24 h内降解率可达到90.97%,半衰期为30.11 min;同时具有良好的结构稳定性和隔热性能。In order to realize decontamination of chemical warfare agents(CWAs),the flexible protective fabrics is developed.The surface modification of ANFs was performed using phosphoric acid treatment,the in-situ growth of MOF-808 on the surface of ANFs was realized hydrothermal method,and the MOF-808@ANF aerogel materials were prepared by ice template technique.The effect of the loading of MOF-808 on its structure and degradation properties of CEES were investigated.The results show that the loading of MOFs can reach 125.56%and the specific surface can reach 408.267 m^(2)/g.The MOF-808@ANF aerogel has good degradation effect on mustard simulants,reaching 90.97%degradation rate within 24 h with a half-life of 30.11 min,and also has good structural stability and thermal insulation properties.
