PDMS/PES中空纤维渗透汽化复合膜的制备
Preparation of PDMS/PES hollow fiber composite pervaporation membrane
【摘要】 用干湿相转化法制备聚醚砜(PES)中空纤维超滤膜,用不同的涂膜方式将聚二甲基硅氧烷(PDMS)溶液涂在经乙醇和正己烷处理过的PES中空纤维底膜的外表面或内表面,制备PDMS/PES中空纤维复合膜,在渗透物侧压力133.33 Pa,通过5%的乙醇-水溶液考察底膜后处理、涂膜方式等因素对膜渗透汽化性能的影响.
【Abstract】 Polyethersulfone(PES) hollow fiber ultrafiltration membranes were fabricated by the dry/wet-spinning method.The PDMS/PES composite membranes were prepared by coating the inner-side or the outer-side of the PES hollow fiber membranes disposed by ethanol and n-Hexane.The effect of post-treatment of the support membranes and coating method on membrane properties was investigated using a 5% ethanol solution at 133.33 Pa.
