本研究開發出一具有油水分離效果的三層不對稱複合纖維膜，並且使用回收廢偏光板保護層之一的三醋酸纖維素(rTAC)及二氧化鈦(TiO2)/氧化石墨烯(GO)來達到油水分離的效果。 實驗總共分成三個部分，首先是製備TiO2, 並利用XRD確認其晶型為銳鈦礦。將 rTAC靜電紡絲於市售不織布基材上。不織布主要增加過濾網的強度及支撐性。 rTAC則提供過濾網孔隙使濾液能順利通過。第二部分為電泳沉積GO使rTAC不只能引入GO上的親水官能基達到親水效果，更加升rTAC平坦化，利於後續TiO2的電泳沉積程序。當二氧化鈦照射紫光時，因為產生氧空缺，所以能導入空氣中的水氣使接觸角下降至5度以下，更有效提升親水層的親水性。實驗第三部分為油水分離實驗，當油水乳化物通過三層不對稱複合纖維膜時，第一層的親水層能有效阻擋油汙，第二層的疏水纖維網能加升濾液流經的速度，增加油水乳化物的水通量。並利用總有機碳分析儀(TOC)來分析殘留於水中的碳濃度。

In this study, a three-layer asymmetric composite fiber membrane with oil-water separation was developed. Recycle cellulose triacetate (rTAC), titanium dioxide (TiO2) and graphene oxide had been used. The experiment was divided into three parts. First, TiO2 was prepared and confirmed to be anatase by XRD. rTAC was electrospun onto a commercially available nonwoven substrate. Nonwovens mainly increase the strength and support of the filter. rTAC provides the pore so that the filtrate can pass smoothly. The second part is the electrophoretic deposition of GO , not only introduce the hydrophilic function on the rTAC to achieve the hydrophilic effect, but also increase the rTAC flattening, which will make electrophoretic deposition of TiO2 more easily. When the titanium dioxide is irradiated with violet light, it will be defeat on TiO2 surface. which can be introduce water vapor so that the contact angle is reduced to 5 degrees or less, and the hydrophilicity of the hydrophilic layer is more effectively promoted. The third part of the experiment is oil and water separation experiment, when the oil and water emulsion through the three layers of asymmetric composite fiber membrane, the first layer of hydrophilic layer can effectively block the oil, the second layer of hydrophobic fiber network can increase the speed of filtrate flow, Increase the water flux of oil and water emulsion. And the permeate carbon concentration in the water was analyzed using a total organic carbon analyzer (TOC).  In this study, a three-layer asymmetric composite fiber membrane with oil-water separation was developed.
