In this study, a dual-layer hollow fiber nanofiltration (NF) membrane was fabricated with an inner layer of poly(vinylidene fluoride) (PVDF) via thermally induced phase separation (TIPS), and an outer layer of cellulose diacetate (CA) via non-solvent induced phase separation (NIPS). The intermediate-tr

A series of thermo-sensitive polyurethane-NIPAAm hydrogel membranes with various cross-linking densities have been obtained by the UV-curable method. Sucrose, β-cyclodextrin and dextran were used as the model compounds to evaluate the solute permeability through the hydrogel membranes. The solute pe

A model was developed to describe the desalination process of an aqueous solution consisting of a salt and a neutral solute using electrodialysis (ED). Under the assumption of plug flow in compartments, the ED process was analyzed in two-dimensional directions of the electric field and flow to get t

A temperature-sensitive N-isopropylacrylamide (NIPAAm) grafted polyethylene microporous membrane was prepared by the plasma-induced graft polymerization technique. The SEM observed that the poly(N-iso-propylacrylamide) (PNIPAAm) chains grafted on the membrane surface exhibited difference configurati

A temperature stimuli-responsive polymer, poly(N-isopropylacrylamide) (PNIPAAm), has been grafted into tubular-type porous polyethylene (PE) membranes by the plasma-induced graft polymerization technique. A wide range of grafting was achieved by varying grafting conditions such as monomer concentrat

Permeation experiments of KCl, NaCl, LiCl, MgCl2, MgSO4 and K2SO4 solutions were carried out using two commercial nanofiltration membranes, which were NF45 (Dow Chemical Corporation) and SU200 (Toray Corporation) membranes. The effects of the type and the concentration of electrolytes as well as the
