摘要
本文设计制备了一种基于聚醚砜微孔膜的金属有机骨架膜复合材料,并将其用于有机含氮化合物的快速检测。以紫外辐射接枝改性的PES膜作载体,诱导Cu3(BTC)2晶体在其表面生长,对得到的复合膜材料进行结构及性能表征。XRD和SEM结果表明复合膜中晶体具有较高的纯度和结晶度。此外,该复合膜材料在有机含氮化合物的水溶液中发生荧光淬灭现象,表现出在荧光传感器方面潜在的应用价值。
A metal-organic framework membrane composite based on polyethersulfone microporous membranes was designed and fabricated,and was applied to the rapid detection of several organic nitrogen compounds in water.Cu3(BTC)2 crystals were induced to grow on the surface of PES film which was modified by ultraviolet radiation.The structure and properties of the composite membrane were characterized.XRD and SEM results show that the crystals in the composite membranes have high purity and crystallinity.In addition,the fluorescence quenching of the composite in aqueous solutions of organic nitrogen compounds shows potential application in fluorescence sensors.
