Elucidating the cross-linked network and microstructure of polyamide based nanofiltration membrane (2026)
Abstract
The polyamide (PA) nanofiltration membrane (NF) provides a low-cost technology to solve the challenge, such as desalination and resource recovery. The PA layer serves as the separation layer which is principally responsible for permeability and selectivity. Small/wide angle X-ray scattering (SAXS/WAXS) allows to quantify the polymer-chain compaction, cross-linked density and aggregation-induced cluster formation. This project aims to elucidate the cross-linked network and nanoscale structure variation of PA layer and evaluate quantitative relationships with membrane performance.
