Beschreibung
Zusammenfassung:	According to the FPEOAA/UiO-66-NH2/PEI modified PVDF MOF membrane provided by the invention, UiO-66-NH2 and polyethyleneimine are deposited on the surface of a polyvinylidene fluoride membrane to form a deposition membrane, and then FPEOAA is grafted on the surface of the deposition membrane to carry out hydrophilic and oleophobic modification on the UiO-66-NH2 to prepare the MOF membrane. The MOF membrane provided by the invention is simple and convenient in preparation method, low in production cost, stable in membrane surface crystal structure and good in hydrophilic and oleophobic performance. 本发明提供的一种FPEOAA/UiO-66-NH2/PEI改性PVDF的MOF膜，将UiO-66-NH2和聚乙烯亚胺沉积到聚偏氟乙烯膜表面，形成沉积膜，再在沉积膜表面接枝FPEOAA对UiO-66-NH2进行亲水疏油修饰制得所述MOF膜。本发明提供的MOF膜制备方法简便、生产成本低且膜表面晶体结构稳定且亲水疏油性能良好。
