Preparation, Characterization, and Separation Performances of Novel Surface Modified LbL Composite Membranes from Polyelectrolyte Blends and MWCNT

Abstract: Here, it was aimed to modify the surface of NF90 with layer by layer (LbL) blended poly(allylamine hydrochloride) (PAH)‐chitosan (CHI) and poly(acrylic acid) (PAA) with/without functionalized multiwalled carbon nanotube (fMWCNT) for reverse‐osmosis applications. Using Quartz Crystal Microbalance Dissipation monitoring, it was observed that PAH‐CHI/PAA LbL films grew linearly after a few bilayers and no LbL film degradation occurred during synthetic seawater treatment. Thermal degradation of all LbL blended mem… Show more

“…Carbon nanotubes or single layers of graphene rolled into a cylinder shape, have been commonly applied and evolved into diverse research directions including medical applications. CNT usually exists in 2 phases, single-walled and multiwalled, with different characteristics properties [28][29][30][31][32][33]. There are different types of techniques that have been improved for synthesizing CNT which mainly involve vapor phase routes.…”

“…Considering the significant improvement in separation and ion rejection of LbL blend structured membranes in the presence or absence of multiwall carbon nanotubes (MWCNT) [47] compared to ones prepared from single anionic and cationic PE couples [33], we assembled membranes from anionic blend PEs in the study. Apart from the using of two different negatively charged PE solutions, one solution comprising of anionic PE blends was used.…”
