Abstract

PU material is promising in pervaporation application. Polyether-based PU prepolymers were used to prepare a series of PU membranes. Then, the structure and properties of the above-prepared membrane materials were characterized by means of FTIR and swelling experiment. And the performance of pervaporation separation of phenol/water was studied. The result shows that The swelling degree is decreased by the addtition of zeolite. Using solution with phenol (0.5wt %) in water. With feed temperature increased, there’s an anti-trade-off phenomenon. At 80 °C, the flux is 319.95 kg• m•m-2•h-1, and separation factor is 7.19.
