Ionic strength directed self-assembled polyelectrolyte single-bilayer membrane for low-pressure nanofiltration
文献摘要：
Layer-by-layer assembly is a versatile techni-que for fabricating nanofiltration membranes,where multiple layers of polyelectrolytes are usually required to achieve reasonable separation performance.In this work,an ionic strength directed self-assembly procedure is described for the preparation of nanofiltration membranes consisting of only a single bilayer of poly(diallyldimethy-lammoniumchloride)and poly(sodium-4-styrenesulfoate).The influence of background ionic strength as well as membrane substrate properties on the formation of single-bilayer membranes are systematically evaluated.Such a simplified polyelectrolyte deposition procedure results in membranes having outstanding separation performance with permeating flux of 14.2±1.5 L·m-2·h-1·bar-1 and Na2SO4 rejection of 97.1％±0.8％under a low applied pressure of 1 bar.These results surpass the ones for conventional multilayered polyelectrolyte membranes.This work encompasses an investigation of ionic strength induced coiling of the polyelectrolyte chains and empha-sizes the interplay between-polyelectrolyte chain config-uration and substrate pore profile.It thus introduces a new concept on the control of membrane fabrication process toward high performance nanofiltration.
