摘要

超疏水表面（水滴接觸角> 150°，滾動角< 10°）由於其在學術研究與工業上的廣大應用性吸引了相當多的注意。奈米碳管在超疏水特性上的應用非常廣泛，有相當多的相關研究被發表。本實驗利用物理沉積法製作奈米碳管/膨脹石墨/高分子複合薄膜，並針對不同組成探討其成膜性與超疏水性質的影響。針對製備出來的奈米碳管/膨脹石墨/高分子複合薄膜我們分別以電子顯微鏡、接觸角量測儀以及鉛筆硬度測試法，去量測與觀察複合薄膜的表面微結構、潤濕特性及機械性質。此外，我們也觀察溶劑浸泡、熱處理對於奈米碳管/膨脹石墨/高分子複合薄膜超疏水特性的影響。實驗結果發現，結合奈米碳管/膨脹石墨/高分子三種材料之複合薄膜經適量高分子二次改質後可得到奈用性質最佳的超疏水複合薄膜。

In this paper, we report a facial method for fabricating stable conductive superhydrophobic films from expanded graphite (EG)/carbon nanotube (CNT)/polymer composites. This method possesses the advantages of being both simple and inexpensive as well as utilizing non-fluorine-containing compounds. The as-prepared EG/CNT/polymer composites exhibit a good superhydrophobicity with a high water contact angle (162o). A sliding angel of 6o for a 6 L droplet indicates excellent non-sticking behavior. Furthermore, the superhydrophobic EG/CNT/polymer composites had excellent environmental stability with regard to both heating and organic solvent treatment in terms of the contact angle to water. Such superhydrophobic coatings have potential applications in microfluidic devices, liquid transportation, and nonwetting surfaces.
