    摘要: 本研究利用Polysulfone/聚乙二醇摻合製備成具有高選擇性及高透過濾薄膜。本計劃摻合以不同分子量之聚乙二醇(PEG)與聚嗍碸(PSF)薄膜中,製備出親疏水比例不同之聚嗍碸/聚乙二醇(PSF/PEG)複合薄膜,並利用小分量PEG對水分子增進擴散(mobility enhanced)之效果,有效提昇複合膜之分離性能膨潤性因PEG添加可增加可使滲透蒸發透過率增加,而親水性效應,則可維持其擴散選擇性並增加水合之效果,因此本研究中polysulfone/PEG薄膜,滲透蒸發性能遠比polysulfone提昇,本研究並探討滲透蒸發操作條件之變化,如滲透蒸發之進料濃度、溫度變化等,以對最佳分離性能之影響。
