采用粒子填充的聚丙烯腈 (PAN)作为基膜材料 ,纺制成中空纤维 .对基膜进行拉伸、热定型等后处理 ,并在此基础上研制了壳聚糖 /聚丙烯腈中空纤维复合膜 ,考察了基膜的改性及不同操作条件对复合膜分离性能的影响 .发现采用该基膜制备的复合膜对乙醇 -水体系具有很好的分离性能
Particle-filled polyacrylonitrile (PAN) was used as the base material and spun into hollow fibers, and the base film was subjected to stretching and heat-setting treatment. On this basis, chitosan / polyacrylonitrile hollow fiber The effects of the modification of the base film and the different operating conditions on the separation performance of the composite membrane were investigated.The composite membranes prepared by the base membrane showed good separation performance for the ethanol-water system
