摘要
Hydroxyl terminated polybutadiene (HTPB) based polyurethane (PU)-polystyrene (PS) interpenetrating polymer network (IPN) was prepared and characterized by FTIR, TGA, WCA, swelling experiments, and SEM. The IPN was used for pervaporation (PV) recovery of butanol. Both the permeation flux and separation factor increased with feed temperature, and both water and butanol fluxes increased with feed concentration while no obvious effect of concentration on separation factor was found. Through the formation of IPN structure, the total flux of HTPB based PU increased greatly with the decrease of separation factor. At the feed temperature of 60 degrees C, the IPN membrane obtained a total flux of 613.3 g/m(2)h with a separation factor of 6.15.
