TS102.6; A hydrophilic composite polybutylene terephthalate (PBT)/polyvinyl alcohol (PVA) membrane with great potential applications in biological filtration has been investigated in this research. The composite membranes were fabricated by electrospinning with PBT meltblown nonwovens as the receiving substrate. These membranes have higher strength than the conventional single layer electrospinning membrane, smaller pore diameter than the common meltblown PBT nonwovens, good hydrophilicity, and high water flux. The flux of the composite membrane was 5.97×103 L/(m2·h) for 5％(mass fraction) glucose solution, which was higher than that of the commercial blood filtration membranes. The optimal process for preparing PBT/PVA composite membranes was obtained by orthogonal experiments. In general, the preparation process is simple and easy to control.
