摘　　要：提供了一种UiO-66-NH2高效负载棉织物的制备方法,得到的功能棉织物具有良好的化学战剂催化降解效果。首先利用γ-缩水甘油醚氧丙基三甲氧基硅烷(GPTMS)对棉织物进行预处理,然后利用溶剂热合成法在预处理棉织物上原位生长UiO-66-NH2晶体,由此制备的负载UiO-66-NH2棉织物经10次皂洗后,其UiO-66-NH2负载量无明显变化,表明该织物具有良好的耐皂洗牢度。此外该负载UiO-66-NH2棉织物对有机磷酸酯类化学战剂模拟物甲基对氧磷(DMNP)的催化降解转化率在210 min时高达70.73%,半衰期约为30 min。This work provides a highly efficient method for loading UiO-66-NH2 on cotton fabrics.The obtained functional cotton fabrics exhibited remarkable activity in catalyzing degradation of chemical warfare agents.Specifically,cotton fabrics were pretreated withγ-(2,3-epoxypropoxy)propytrimethoxysilane(GPTMS),on which UiO-66-NH2 crystals were grown in-situ via solvothermal synthesis.The UiO-66-NH2 loaded cotton fabrics showed good wash fastness in that no significant change on the amount of loaded UiO-66-NH2 were noticed after 10 times soap-washing cycles.Moreover,the modified fabrics exhibited remarkable performance in catalyzing the degradation of dimethyl p-nitrophenyl phosphate(DMNP),a simulant for the chemical warfare agents of the organic phosphate group.Half-life for the catalyzed degradation of DMNP was about 30 min and the conversion rate reached 70.73%in 210 min.
