Fabrication of Crosslinkable Hollow Fiber Membranes for Pervaporation Dehydration

Integrally-skinned asymmetric Polyetherimide/Poly (vinyl alcohol) (PEI/PVA) hollow fber membranes for pervaporation dehydration were fabricated by non-solvent induced phase inversion. PVA inside the PEI matrix could be crosslinked to provide membrane performance stability during long term operation. The effects of different PEI/PVA blend ratio, external coagulant type and...

Heterogeneous Functionalization of Polyethersulfone: A New Approach for pH-Responsive Microfiltration Membranes with Enhanced Antifouling Properties

In this work, 2,2’-azo-bis-butyronitrile (AIBN) was exploited as an initiator for the successful bulk heterogeneous functionalization of polyethersulfone (PES) using polymethacrylic acid (PMAA), for the first time. To this end, pH-responsive and exceptionally low fouling membranes of extremely low grafting degrees with low adhesion and high rejection of protein were fabricated. An added advanta...

Progress and Perspective of Antifouling, Pressure Driven, Flat-Sheet Nanocomposite, Polymeric Membranes in Water Treatment

Membrane filtration, especially based on the size exclusion phenomenon, has long been established due to its abilities to addressing the growing demands of the clean water of the world’s population. However, widespread applications of the membranes face several challenges including chemical vulnerability, thermal deterioration, and biological degradation of the membranes that transpire while re...

Adsorption of the endocrine-active compound estrone on microfiltration hollow fiber membranes.

Results of studies reported here show that adsorption could result in considerable accumulation of hormones on hydrophobic hollow fiber membrane surfaces during filtration of trace-hormone-containing feed solutions with a linear adsorption isotherm applicable over the majority of the estrone concentration range examined (2.6-154 ng/L). Models based on both diffusion and surface reaction limitat...

Temperature-modulated water filtration using microgel-functionalized hollow-fiber membranes.

In the present work, we investigate the potential of aqueous polymer microgels in membrane technology, especially for filtration applications. The poly(N-vinylcaprolactam)-based microgels exhibit thermoresponsive behavior and were employed to coat hollow-fiber membranes used for micro- and ultrafiltration. We discuss the preparation of microgel-modified membranes (by "inside-out" as well as "ou...
