由於現代工業扶搖直上的發展,空氣污染相當嚴重,如PM2.5的影響甚大,然而奈米纖維可廣泛應用於氣體或是液體的濾材上,且搭配簡單便利的靜電紡絲技術即可量產。因此,本研究採用靜電紡絲技術製備奈米纖維薄膜,探討奈米纖維薄膜的呼吸阻抗和過濾效果。
本研究中使用聚己內酯(Polycaprolactone,簡稱PCL)、竹炭粉(Bamboo charcoal,簡稱BC)、幾丁聚醣(Chitosan,簡稱CS) ,利用不同的製程方法製備出奈米纖維,並且使用各種分析儀器來檢查奈米纖維的性質和型態。如掃描式電子顯微鏡(SEM)、熱重分析儀(TGA)、熱差式掃描分析儀(DSC)、比表面積和孔隙率分析儀(BET)、抗菌測試和空氣過濾分析。
由SEM中觀察出纖維直徑確實達到奈米級。TGA中觀察出添加0.025克BC具有更高的熱裂解溫度。DSC分析中,證明PCL的熔點確實為59-64℃。通過BET測試,比表面積為2~5 m2/g,平均孔徑為12~48 nm。抗菌試驗表明纖維具有抗菌作用。在空氣防護效率的層面,可過濾掉96.45%的0.26μm以上之粒子,證明纖維確實能夠有效地阻擋空氣中的PM2.5。


關鍵字:竹碳粉、靜電紡絲、幾丁聚醣、PM2.5

Booming industry has also produced huge pollution problems on earth. Air pollution is severe now, such as PM2.5. It constitutes a serious threat to public health. Therefore, this study is to use electrospinning technology to prepare nanofibrous mats and investigate respiratory impedance and filtration effects of the nanofibrous mats.
In this study, we used polycaprolactone (PCL), bamboo charcoal (BC), and chitosan(CS) to create nanofiber in different processes and use a variety of analysis instrument to inspect properties and morphology of the nanofibers such as scanning electron microscope (SEM), thermogravimetric analyzer (TGA), thermal differential scanning analyzer (DSC), Specific Surface Area and Porosimetry Analyzer (BET), Antibacterial test and Air Filtration for analysis.
In the SEM, the average fiber diameter can be observed between 100 nm and 200 nm. In the analysis of TGA, adding 0.025 grams of BC has a higher thermal cracking temperature. In the analysis of DSC, it proves that the melting point of PCL is 59-64 °C. By BET, specific surface area is 2~5 m2/g and average pore diameter is 12~48 nm of the fiber. The information can prove the fiber is mesoporous material. Antibacterial test indicating that the fiber has an antibacterial effect. For the test of air pollution prevention, the fiber is produced to form mask, which filtration efficiency is 96.45% of 0.26μm particles above. In other words, it can almost block PM2.5 of air in our environment. The addition of bamboo charcoal (BC) and chitosan(CS) can effectively improve the filtering effect.

Key word : Bamboo charcoal、Electrospinning、Chitosan、PM2.5
