The exploration of novel O/W filters having not only high permeation and rejection but also durable performance is a key driver of membrane material research. In this study, a glass fiber membrane (GF) was grafted with hyperbranched polyethyleneimine (HPEI) via a two-step process and used for O/W separation. The silanol group in the GF was reacted with epichlorohydrin followed by the reaction with...
A series of stimuli-responsive reverse (RO) membranes were prepared by tethering three stimuli-responsive polymers, poly (sulfobetaine methacrylate) (PSBMA), poly (4-(2-Sulfoethyl)-1-(4-vinyl-benzyl) pyridinium betain) (PSVBP) and poly (N-isopropylacrylamide) (PNIPAM) onto the surface of a commercial thin-film (TFC) RO membrane via surface-initiated graft polymerization. The membrane surface was characterized...
