Material transport properties of polymer–gel composite‐charged mosaic membrane with and without reinforcement [II]

Abstract

ABSTRACT:The 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 L p and . Filtration coefficient, L p and salt permeability coefficient were estimated by taking account of active layer thickness of composite polymer gel. The L p and 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 showed negative value, which suggested the preferential material transport to solvent transport. This indicates that was independent of active layer thickness. Furthermore, the results of transport properties of CCMM with reinforcement were supported by the membrane potential measurements

Effect of functional group of ferrocene redox substance on the transport properties of newly designed ion exchange membrane prepared from polymer gel

“…The development of ion exchange membrane of high chemical, thermal and mechanical stabilities, which meet growing demands of aforementioned process, is of great importance. So far the works concerning the charged mosaic membranes have been reported to elucidate the mechanism of ion transport within membranes 2–10. However, its interior are too complex to understand the function of mosaic polymer membranes clearly because the charged mosaic polymer membrane consist of two kinds of fixed charges, positive and negative polymeric exchange sites, and membrane matrix material.…”
