采用层层自组装的方式在芳纶织物的表面负载金属有机框架材料(MOF)Fe-BTC。通过红外光谱、扫描电镜、能谱分析了Fe-BTC@芳纶的表面形态以及组成结构。并测试了Fe-BTC@芳纶催化双氧水降解异丙隆的性能。结果表明:循环自组装20次的Fe-BTC@芳纶复合材料在双氧水浓度为20mmol/L下,24h可将5mg/L异丙隆完全降解。Fe-BTC@芳纶对大肠杆菌的抑菌率达到了97.4%,表明Fe-BTC@芳纶在水处理和化学防护方面具有潜在的应用前景。
Fe-BTC was loaded on the surface of aramid fabric by layer-by-layer self-assembly method.The surface morphology and composition of Fe-BTC@aramid fabric were analyzed by FT-IR,SEM and EDS.The catalytic performance of the fabric in the degradation of isoproton by H2O2 was also tested.The results showed that 5mg/L isoproturon can be completely degraded by the fabric within 24h under the best condition:20 times of assembly cycles,hydrogen peroxide concentration 20mmol/L.The antibacterial rate of the fabric against Escherichia coli reached 97.4%.It indicated that the fabric had potential application prospects in water treatment and chemical protection.
