摘要

本文屬超疏水薄膜與織物貼合之研究，首先先製作超疏水薄膜，由於聚四氟乙烯表面呈疏水性，不易與其他材料貼合。藉由氧電漿處理可使其表面能大幅增加成為親水性，易與其他織物貼合，因此將超疏水薄膜之背面以氧電漿進行改質，並分別以不同瓦數(W)、電漿處理時間(min)，探討其改質之表面及其貼合效果。
由實驗結果發現，FTIR圖譜可看經出氧電漿處理後，確實表面已有改變，由SEM、AFM觀察電漿所造成之刻蝕效果，發現隨著電漿處理功率、時間的增加，造成表面蝕刻的加深及均勻，對於貼合更是有所幫助。拉伸強度隨著電漿處理時間及功率的增加亦會有些許的提升。剝離強度因薄膜本身遭到破壞，強度不如預期，但仍可看出隨功率及時間的提升對其強度具有明顯的提昇。由SEM觀察，證實氧電漿對薄膜表面產生蝕刻效果會影響膠黏性。貼合後子織物經接觸角測試，發現電漿改質並未穿透薄膜而使原超疏水面結構產生改變。貼合後的織物經水洗後，表觀結構亦未因水洗而遭受嚴重破壞，因此接觸角未受影響。但經過摩擦測試後，由於表面的結構已有些遭受磨損，故接觸角下降約10°。

The paper is to adhere the nano super-repellant film to fabrics. Since the the nano super-repellant film was not easy to adhere to the fabrics, the plasma treatment was used to improve the adhesion between PTFE and fabrics. The PTFE surface was treated with different power (W) and time (min) by O2 plasma. For the effect of O2 plasma treatment on etching, it showed that the deeper and more uniform holes were formed as more power and longer time were applied. It could be observed by SPM and SEM and helpful to the adhesion. In consideration of the mechanical properties, it was found that both the breaking load and peel strength of adhered fabrics were increased with more plasma treatment (power and time). For the contact angle test, it was found that the contact angle was no loss after being washed, because of its hydrophobic structure not being destroyed. Nevertheless, the contact angle was decreased about 10° after its rubbing, this was due to the structure of hydrophobic surface showing some destruction.
