NH₂-MIL-53 membranes were in situ prepared on modified polyvinylidene fluoride (PVDF) ultrafiltration membranes by solvothermal method for nanofiltration. The effect of reaction temperature, monomer concentrations and reaction time, as well as the reusability and stability of NH₂-MIL-53/PVDF membranes, were studied. The membrane structure and performance could be conveniently tuned by reaction temperature, concentration, and reaction time. NH₂-MIL-53/PVDF membranes displayed high rejection (>92%), large permeability (>500 L m⁻²h⁻¹ MPa⁻¹) and excellent stability for different dyes (Mw > 300) solutions, making them attractive candidates for dyes separations.

采用溶剂热法在改性聚偏氟乙烯（PVDF）超滤膜上原位制备了NH ₂ -MIL-53膜。研究了反应温度，单体浓度和反应时间以及NH ₂ -MIL-53 / PVDF膜的可重复使用性和稳定性的影响。可以通过反应温度，浓度和反应时间方便地调节膜的结构和性能。NH ₂ -MIL-53 / PVDF膜显示出高截留率（> 92％），大渗透性（> 500 L m ^-2 h ^-1 MPa ^-1）和对不同染料（Mw> 300）溶液的优异稳定性，使其具有吸引力染料分离的候选对象。
