Tetraethylene pentaamine-based polyamide membranes (TEPA) were constructed through crosslinking with trimesoyl chloride (TMC) and further modified by grafting with various crown moieties, including 12-crown-4, 15-crown-5, and 18-crown-6.

The pristine TEPA membrane showed high permeance for monovalent cations, while there were significant interactions with Na⁺ and K⁺ ions on the 12-crown-4 grafted membrane, facilitating the transport of Li⁺ ions, in consistent with reported experimental findings. When exposed to binary mixtures of Li⁺/Na⁺, Li⁺/K⁺, Li⁺/Mg²⁺, and Li⁺/Ca²⁺, the diffusion barrier for Li<sup>+</sup> ion was lowered by the polyether heteroatoms in the 12-crown-4 grafted membrane, which continuously screened the competing ions.
