Special Issue Information

Dear Colleagues,

Hollow fiber membranes are ubiquitously used in industrial separations and has received increased interest in the fields of gas separation, resources recovery, water treatment, refrigeration systems and biomedical separation for its self-supporting property, good flexibility, high packing density, large specific surface area, and high energy-efficient.

The prominent objective of this Special Issue is to provide an opportunity for researchers in this field of to share their high-quality research and review papers on all aspects related to Hollow Fiber Membrane Technology and Applications. Topics of interest include, but are not limited to, the following:

  • Hollow-fiber membrane based new materials including COF, MOF, GO, MXene…
  • Fabrication techniques including TIPS, NIPS, stretching, electrospinning…
  • Hollow-fiber membrane for membrane contactor, membrane reactor, Membrane aeration…
  • Emerging application like CO2 capture, artificial lung, forward/reverse osmosis, nanofiltration, solvent extraction, membrane deoxygenators, renal dialysis, membrane distillation/absorption, membrane bioreactor, refrigeration systems.
  • Modeling and simulation of hollow-fiber membrane processes.
  • Reinforcing or modification of hollow fiber membrane.

We look forward to receiving your contributions.

Positively charged nanofiltration (NF) technology is considered a green and low-cost method for mono/divalent cation separation. Nevertheless, the separation rejection mechanisms of these NF membranes have yet to be extensively investigated. In this work, we fabricated a thin-film composite (TFC) hollow-fiber (HF) NF membrane with a positively charged surface via modification of the nascent interfacial polymerization layer using a branched polyethyleneimine (BPEI)/ethanol solution. Then, we extensively investigated its selective separation mechanism for mono/divalent cations. We proposed and proved that there exists a double-charged layer near the membrane surface, which helps to repel the divalent cations selectively via Donnan exclusion while promoting the fast penetration of monovalent cations. Meanwhile, the membrane skin layer is loose and hydrophilic due to the loose BPEI structure and the abundance of amine groups, as well as the changed fabrication conditions. In this way, we achieved very good mono/divalent cation selectivity and relatively high water permeance for the as-prepared HF NF membrane. We also obtained good anti-fouling, anti-scaling, and acid resistance, and long-term stability as well, which are urgently needed during practical application. Furthermore, we successfully amplified this HF NF membrane and proved that it has broad application prospects in mono/divalent cation separation. Full article
