摘      要：Natural rubber/styrene-butadiene-styrene(NR/SBS)membrane was prepared by solution blend,and then used for recovery of butanol from its dilute solution by pervaporation(PV).The thermodynamic and mechanical properties of NR/SBS blend membrane were characterized by TGA and tensile test,respectively.A layer of relatively dense blend membrane with the thickness of about 37μm was closely cast on a layer of porous polyvinylidene difluoride(PVDF)*** there was no obvious phase separation observed between the interface of two *** flux and separation factor increased with increasing feed *** flux increased as feed concentration increased *** blend membrane which got the best performance obtained membrane separation factor of 28.8 with total flux of 2695.2 g/m^(2)h at 70℃ when feed concentration was 4.00wt%.
