Interlayered thin-film nanocomposite (TFN) membranes have shown the potential to boost nanofiltration performance for water treatment applications including removal of organic micropollutants (OMPs). However, effects substrates been overlooked when exploiting and evaluating efficacy certain kinds interlayers in tailoring membrane performance. Herein, a series TFN were synthesized on different porous with identical metal-organic framework nanosheets. It was revealed that interlayer introduction could narrow but not fully eliminate difference properties among polyamide layers formed substrates, variation prominent distinct aspects. For small pore sizes exerting severe transport hindrance, introduced mainly enhanced permeance by affording gutter effect, while it be more effective reducing size improving interfacial polymerization platform avoiding PA defects using large-pore-size substrate. By matching selected well, superior obtained simultaneously higher OMP rejections compared three commercial membranes. This study helps us objectively understand efficacies attain breakthroughs efficient treatment.

Thin-Film Composite Membranes Interlayered with Amphiphilic MoS₂ Nanosheets via Controllable Interfacial Polymerization for Enhanced Desalination Performance

Environmental Science & Technology, Journal Year: 2024, Volume and Issue: 58(26), P. 11855 - 11863

Published: June 14, 2024

Polyamide (PA)-based nanofiltration (NF) membranes have demonstrated extensive applications for a sustainable water-energy-environment nexus. A rational control of interfacial polymerization (IP) is highly efficacious to enhance NF separation performance yet remains technical challenge. Herein, we proposed regulation strategy constructing amphiphilic molybdenum disulfide/cetyltrimethylammonium bromide interlayer atop the Kevlar hydrogel substrate. The nanosheet interlayered membrane exhibited crumpled PA surface with an elevated cross-linking degree 76.9%, leading excellent water permeance (16.8 L m
