Polyurethane

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

This work investigated the preparation of composite membranes by simultaneous casting of polyurethane and polyethersulfone solutions, to form the top and the support layers, respectively. These membranes are intended to be used for propylene/propane separation. Polyvinylpyrrolidone was used as an ad
