摘要
介绍了热致相分离法和熔融拉伸法制备聚丙烯中空纤维膜的研究进展。首先重点归纳了热致相分离法中稀释剂、冷却速率、成核剂等因素和熔融-拉伸法中退火温度、熔融拉伸比等制膜工艺条件对聚丙烯中空纤维膜结构与性能的影响;然后对聚丙烯中空纤维膜在体外膜肺氧合、膜蒸馏、膜吸收、膜萃取等领域的应用进行介绍;最后对目前聚丙烯中空纤维膜在制备和应用领域所遇到的挑战及前景进行讨论和展望.
The recent research progress of hydrophobic polypropylene(PP)hollow fiber membranes prepared via thermally induced phase separation(TIPS)and melt-stretching(MS)was reviewed.The effects of diluent,cooling rate and the nucleating agent on the membrane formation process via TIPS,and the effects of annealing temperature and melt drawing ratio on the structure and properties of PP hollow fiber membranes via the MS method were summarized firstly.Then,the applications of PP hollow fiber membrane in different fields including extracorporeal membrane oxygenation,membrane distillation,membrane contactors and other aspects were discussed.Finally,the challenges and prospects of the preparation and application of PP hollow fiber membrane were proposed.
