Ultrathin nanofiltration membrane assembled by polyethyleneimine-grafted graphene quantum dots

Chao Yang et al.

Summary: Embedding PEI-functionalized graphene quantum dots into the selective layer through interfacial polymerization enables the creation of abundant nanopores in the membrane, leading to the successful preparation of high-performance nanofiltration membranes. The ultrathin thickness and increased pore size contribute to the competitive pure water permeance and high salt rejection rate of the PA-NGQD600 membrane.

Ultraselective and Highly Permeable Polyamide Nanofilms for Ionic and Molecular Nanofiltration

Pulak Sarkar et al.

Summary: This study reports the development of ultraselective and highly water permeable polyamide nanofilm composite nanofiltration membranes, achieved by precisely controlling the kinetics of the interfacial polymerization reaction. These membranes exhibit exceptional rejection rates for divalent salt and demonstrate ion selectivity significantly higher than commercially available membranes. The fabrication process is scalable for membrane manufacturing.

A Nano-Heterogeneous Membrane for Efficient Separation of Lithium from High Magnesium/Lithium Ratio Brine

Huawen Peng et al.

Summary: A new strategy for preparing positively charged nanofiltration membranes has been reported, which shows ultrapermeable and selective separation of lithium ions from concentrated magnesium/lithium mixtures. The modification of the membranes with a new electrolyte monomer improves water permeance and stability in continuous nanofiltration. High lithium flux has been achieved at 6 bar operation pressure.

Janus charged polyamide nanofilm with ultra-high separation selectivity for mono-/divalent ions

Ze-Lin Qiu et al.

Summary: A facile and universal method was developed to fabricate polyamide NF membranes with ultra-high separation selectivity to both mono-/divalent anions and cations. By incorporating PAMAM dendrimers with different terminal quaternary ammonium groups into the polyamide matrix, the charge properties and network structures of the nanofilms were modulated, resulting in a high efficiency in mixed ion separation process. The Janus charged PA nanofilm, contributed by the heterogeneous distribution of PAMAM G5-TAC2, exhibited ultra-high separation selectivity to mono-/divalent anions and cations above 65, achieved through the synergistic effect of steric and Donnan effects.

Polyamide nanofilms with linearly-tunable thickness for high performance nanofiltration

Cheng-Ye Zhu et al.

Summary: The study presents a rational strategy to linearly regulate the thickness of polyamide nanofilms by using glycerol as an additive, making the interfacial polymerization process controllable. The synthesized nanofilms exhibit tunable cross-linking degree and pore size, providing the polyamide membranes with desirable water permeability and salt selectivity. This strategy opens up an eco-friendly and scalable avenue for synthesizing polyamide nanofilms, crucial for various membrane applications like nanofiltration, reverse osmosis, and forward osmosis.
