Abstract
AbstractThe charged mosaic membranes (CMM) without reinforcement and the composite charged mosaic membrane (CCMM) with reinforcement were investigated in terms of solute and solvent transport. The composite charged mosaic membrane (CCMM) with reinforcement showed an unique transport behavior such as preferential material transport Lp and ω. Filtration coefficient, Lp and salt permeability coefficient ω were estimated by taking account of active layer thickness of composite polymer gel. The Lp and ω values of CCMM with reinforcement were larger than those of charged mosaic membrane (CMM) without reinforcement. On the other hand, the reflection coefficient of CCMM σ showed negative value, which suggested the preferential material transport to solvent transport. This indicates that σ was independent of active layer thickness. Furthermore, the results of transport properties of CCMM with reinforcement were supported by the membrane potential measurements. © 2006 Wiley Periodicals, Inc. J Appl Polym Sci 99: 3507–3513, 2006
