靜電紡絲近年來不管是在學術界與產業界都有著各方面的研究，尤其在空氣過濾方面更能顯示其優勢其對PM2.5以下的微粒過濾效果特別明顯。有鑑於以往文獻中有關空氣過濾材的測試方法發現，大部分的實驗方式都以鹽霧微粒子用來作為過濾效果測試的氣膠種類，但實際上霧霾中危害人體健康的最大元兇是液態的油性氣膠(aerosol)微粒，卻少有文獻資料以液態氣膠作為過濾微粒來討論濾材的油霧過濾效果。因此，本研究主要以提升液態氣膠過濾效果並降低材料壓差為研究目標，以熱塑性聚氨酯(TPU)與聚醯胺(PA6)為原料，再加入具有親油性的多元醇非離子界面活性劑，以靜電紡絲方式噴覆在熔噴不織布上複合製成仿口罩結構之複合不織布，探討改變原料比例以及處理條件的不同，對不同粒徑油性氣膠微粒過濾效率與壓差之影響做一深入研究。

Over past few years, there were numerous studies on Electrospinning Technique that have been carried in academia and industrial field. As in the aspect of air filtration, Electrospinning Technique are able to show its filtration advantages especially on the filtration effectiveness of particulate size less than PM2.5. According to the previous test methods for air filter materials in literatures, most of the experiment methods were based on using salt spray particles as a type of aerosol for filtration test. In fact, the biggest culprit that threatening human health in haze is liquid oily rubber particles where there are only limited research studies discussing on the use of aerosol as filter base and the effectiveness of oil mist filtration. The main objectives of this research are mainly focus to improve aerosol filtration effect and to reduce material differential pressure. In this study, Thermoplastic polyurethane (TPU) and Polyamide (PA6) were two main raw materials. Spinning solution was prepared by adding an activating agent, Poly (Oxyethylene) which has the lipophilic properties and a mask structure composite was able to form by spraying spinning solution on melt-blown nonwoven fabric through Electrospinning Technique. Nevertheless, by changing in different volume ratio of raw materials in different processing conditions, further investigation on the effects of filtration efficiency and differential pressure of different particulate sizes were discussed.
