摘要：
A membrane for fast and efficient separation of Li+ and Mg2+ was successfully prepared by constructing a thin montmorillonite nanosheets (MMTNS) interlayer with carbon nanotubes (CNTs) onto PES substrate. The introduction of MMTNS interlayer decreased the thickness of polyamide layer formed between polyethyleneimine and trimesoyl chloride as well as improved the hydrophilicity of membrane. CNTs expanded the interlayer spacing of MMTNS interlayer and shortened the length of water channels. The optimal CNTs/MMTNS/PA membrane demonstrated high Li+/Mg2+ separation performance with a selectivity of 20.71, and exhibited a permeability of 22.45 L m-2 h- 1, nearly double that of MMTNS/PA membrane.
