Abstract
Polymeric membranes were prepared by crosslinking polyvinylalcohol (PVA) and cyclodextrins (CDs) with epichlorohydrin or hexamethylenediisocyanate. Immobilized CDs were shown to enhance the permeation rate of toluene in a water/methanol pertraction system depending on the CD content (0-50 wt%) and the cavity size (α-, ß-, γ-CD). Further increases were observed by replacing α-CD with an α-CD polyrotaxane. This effect was interpreted by the cooperativity of CD cavities in the toluene permeation across channels formed inside the membrane.
