Preparation and Characterization of Membranes Formed by Nonsolvent Induced Phase Separation: A Review
TL;DR: A review of nonsolvent induced phase separation membrane preparation and characterization for many commonly used membrane polymers is presented in this article, which includes membrane porosity and pore size distribution characterization, membrane physical and chemical properties characterization, and thermodynamic and kinetic evaluation of phase inversion process.
Journal ArticleDOI
Zeolite imidazolate framework hybrid nanofiltration (NF) membranes with enhanced permselectivity for dye removal
TL;DR: In this article, a facile and simple route for fabrication of a uniform MOF/polymer hybrid membrane via the combination of self-assembly and interfacial reaction method was provided.
Journal ArticleDOI
Fabrication of polyamide thin film composite reverse osmosis membranes via support-free interfacial polymerization
TL;DR: Support-free interfacial polymerization (SFIP) as discussed by the authors is a fabrication method of polyamide (PA) thin film composite reverse osmosis membranes, in which a PA layer is first formed at the interface without a support, followed by attachment onto a support.
Journal ArticleDOI
Grafting short-chain amino acids onto membrane surfaces to resist protein fouling
TL;DR: In this paper, three types of natural amino acids, including lysine, glycine, and serine, were chemically grafted onto membranes via carbodiimide chemistry to render highly hydrophilic surfaces, which displayed the intrinsic advantages in high surface coverage, three-dimensional modification, and unsacrificed permeability.

A novel loose-NF membrane based on the phosphorylation and cross-linking of polyethyleneimine layer on porous PAN UF membranes
TL;DR: In this paper, a loose-NF membrane was fabricated by coating the polyethyleneimine (PEI) layer on a hydrolyzed polyacrylonitrile (HPAN) ultrafiltration membrane, followed by phosphorylation with inositol hexaphosphate (IP6) and cross-linking process.

Surface engineerings of polyacrylonitrile-based asymmetric membranes towards biomedical applications: An overview
TL;DR: This review presents various surface engineerings for PAN-based membranes, which mainly refers to grafting polymerization, partially hydrolysis, macromolecule immobilization, and enzyme immobilization.
Journal ArticleDOI
Impact of ambient conditions on SMP elimination and rejection in MBRs.
TL;DR: Here, SMP loading rate was found to have the greatest effect on SMP elimination and thus on concentration in the MBR, and the increased fouling rates at lower temperatures might therefore partly be explained by this increased rejection.
Journal ArticleDOI
Self-assembly of polyelectrolyte multilayer pervaporation membranes by a dynamic layer-by-layer technique on a hydrolyzed polyacrylonitrile ultrafiltration membrane
TL;DR: In this article, the self-assembly of polyelectrolyte multilayer membranes (PEMMs) by using dynamic layer-by-layer (LBL) adsorption technique for pervaporation separation of water/alcohol mixtures was investigated.
Journal ArticleDOI
Nanofiltration membrane prepared from polyacrylonitrile ultrafiltration membrane by low-temperature plasma: I. Graft of acrylic acid in gas
TL;DR: In this paper, a low temperature plasma-induced grafting modifications of polyacrylonitrile (PAN) ultrafiltration membrane were studied to prepare hydrophilic nanofiltration membranes.
Journal ArticleDOI
Preparation of nanofiltration membranes from polyacrylonitrile ultrafiltration membranes
TL;DR: In this paper, the meso-macropores of PAN UF membranes can be easily reduced into the range of micro-mesopores by taking advantage of surface tension forces within the capillary pores during heat treatment in the presence of ZnCl2.
