英文摘要	Two type of composite membranes (NFCM) containing poly (stearyl methacrylate) (PSMA) / poly(ethylene terephthalate) (PET) nanofiber supporting layer, prepared by coaxial electrospinning technology, and poly(vinylidene fluoride) (PVDF) substrate, were prepared using water or ethanol as the coagulation solution. NFCM has the low pressure and high water flux against the bulk PVDF membrane at the same condition. The morphological structure, the pure water flux and the rejection of NFCM show the strong dependence upon the solvent-treated process. The water flux of NFCM@ EtOH is in the range from 100 to 1400 L/(m(2) h); while for NFCM@H2O, its water flux only is between 40 and 220 11(m(2).h), indicating that EtOH shows the greatly influence on the surface porosity of membrane. The tensile strength of membrane changes from 0. 925 MPa of the original PVDF to 4. 28 MPa of NFCM, demonstrating that the incorporated nanofibers can effectively improve the mechanical property of PVDF membrane. Obvious thermal behaviour and the temperature buffering ability appear in NFCM, and it exhibits an active response when temperature is below 50 degrees C. The slowdown amplitude of water flux with temperature is observed in NFCM as compared with the control. The prepared NFCM containing PSMA/PET nanofiber as the supporting layer provides a way to obtain the high-performance composite membrane with the high water flux.
