有別於傳統處理水面上油污外洩問題往往耗時、耗能且效率低。本研究是以水性製程將高分子奈米粒子製備出疏水/親油紡織品分離膜並設計可以應用於大水域水面上浮油清除和回收之集油井並進行理論預測其分離過程。在本研究中設計出一簡易裝置來評估油體流經疏水/親油紡織品分離膜通量的表現，並藉由定義resistance of membrane (RM)來評估油體流經分離膜之阻力，以此為基礎可以用於預測分層油-水混合物之分離狀況，以提供實際應用設計參考，從結果中指出實驗和理論模型的決定係數(R2>0.9941)，代表其方法具備相當高之準確性。藉由調控不同的水性鐵氟龍分散液(PTFE DISP)濃度與浸鍍次數，可以創造出不同孔徑大小及膜厚之分離膜，並影響其通量及突破壓力數值大小，從結果中顯示雖然在分離過程中需要較高的通量，但同時也會有著突破壓力較小的問題。此外，在本研究中顯示不同物理性質之牛頓流體所量測之RM差異不大，因此推測可以應用於其他牛頓流體通量的預測。

Due to the frequent oil spill problem, the development of new oil-water separation methods with high efficiency, low cost and safety has been the popular research. In this work, competent hydrophobic/oleophilic fabric membranes for separating stratified oil-water mixtures can be fabricated by a simple waterborne polymeric nanoparticle coating process and can be used to build up oil collection wells for the oil spill problems. To predict the mass flux and separation time, we design a simple and small apparatus, and derived the mathematical model for low Re Newtonian fluid. The developed model can be used to determine the membrane performance by a membrane resistance, RM, to the Poiseuille flow of a liquid oil driven by gravity; and the agreement between theoretical and experimental results (R2>0.9941) confirmed the validity of the developed model. By coating with various PTFE DISP concentration and multiple coating times, the effective pore size and thickness of fabrics could be varied, and these results will affect the value of flux and water intrusion pressure (WIP). The WIP decrease as the RM decrease, it means that high flux (RM is small) for separating stratified oil-water mixture might face low hydrophobicity problem. Moreover, a fabric membrane with an as-determined value of RM can be used to accurately predict the separation time of stratified oil-water mixture in specific condition.
