Graphene oxide (GO) composite nanofiltration membranes (GO-EDA/Al2O3 membrane) cross-linked by ethylenediamine (EDA) were fabricated on dopamine (PDA) modified alumina ceramic membranes. The covalent bonds enhance the interlayer and interface stability of the as-prepared membranes. A method that can simply adjust the layer spacing of GO composite membranes was proposed. The number of hydroxyl groups inside the GO composite membranes can be changed through varying the drying temperature, thus affecting the pure water permeation and salt rejection of the GO composite membranes. The results show that the thickness of the GO composite membranes fabricated at the drying temperature of 40 ℃ is 50-120 nm. The pure water permeance and the rejection towards Na2SO4 solution are 34 L/(m2·h·MPa) and 87.8%, respectively. The GO composite membranes still remain an excellent stability and a high rejection rate after being immersed in pure water for 680 h.

在经过多巴胺(PDA)预处理的氧化铝陶瓷膜上制备出乙二胺(EDA)交联的氧化石墨烯(GO)复合纳滤膜(GO-EDA/Al2O3膜),解决了界面和层间稳定性问题。并提出一种可简单调控GO层间距的方法,即通过改变膜管的干燥温度改变GO纳米片上羟基的数量,达到调控GO层间距的目的,从而在保证较高盐截留性能的前提下提升GO-EDA/Al2O3膜的纯水渗透性能。结果表明,干燥温度为40 ℃制备的GO-EDA/Al2O3膜,其分离层厚度约50~120 nm,纯水渗透率达34 L/(m2·h·MPa),对Na2SO4的截留率达87.8%。膜在纯水中浸泡680 h后其性能基本保持稳定。

在经过多巴胺(PDA)预处理的氧化铝陶瓷膜上制备出乙二胺(EDA)交联的氧化石墨烯(GO)复合纳滤膜(GO-EDA/Al2O3膜),解决了界面和层间稳定性问题。并提出一种可简单调控GO层间距的方法,即通过改变膜管的干燥温度改变GO纳米片上羟基的数量,达到调控GO层间距的目的,从而在保证较高盐截留性能的前提下提升GO-EDA/Al2O3膜的纯水渗透性能。结果表明,干燥温度为40 ℃制备的GO-EDA/Al2O3膜,其分离层厚度约50~120 nm,纯水渗透率达34 L/(m2·h·MPa),对Na2SO4的截留率达87.8%。膜在纯水中浸泡680 h后其性能基本保持稳定。

Graphene oxide (GO) composite nanofiltration membranes (GO-EDA/Al2O3 membrane) cross-linked by ethylenediamine (EDA) were fabricated on dopamine (PDA) modified alumina ceramic membranes. The covalent bonds enhance the interlayer and interface stability of the as-prepared membranes. A method that can simply adjust the layer spacing of GO composite membranes was proposed. The number of hydroxyl groups inside the GO composite membranes can be changed through varying the drying temperature, thus affecting the pure water permeation and salt rejection of the GO composite membranes. The results show that the thickness of the GO composite membranes fabricated at the drying temperature of 40 ℃ is 50-120 nm. The pure water permeance and the rejection towards Na2SO4 solution are 34 L/(m2·h·MPa) and 87.8%, respectively. The GO composite membranes still remain an excellent stability and a high rejection rate after being immersed in pure water for 680 h.
