摘要註:	本研究主要是利用奈米壓印的方法，將有機材料的聚甲基丙烯酸甲酯（PMMA）與及環氧樹脂（Epoxy）與無機材料奈米四氧化三鐵粒子、奈米氧化鋅、以及奈米雲母，利用溶劑輔助法、混合法、沉積的方法將有機與無機材料作出複合結構表面並利用低表面能含氟高分子修飾，以 ESCA分析，以及SEM觀察面形貌。混合法方面，利用改質的奈米雲母與環氧樹脂以及PMMA先做不同比例的混合，再利用奈米壓印方法於120 ℃下壓力為3 ㎏/cm2，持壓20分鐘後脫膜離型，就可以得到帶有複合表面的圖案，再將此複合表面利用低表面能含氟高分子FOTS修飾後，於疏水性測試，可以得到於添加1 w ％奈米雲母後，水接觸角度為148.2°溶劑輔助法方面，利用奈米氧化鋅與奈米雲母可以均勻分散在乙醇溶液中，再利用奈米壓印法壓印於PMMA表面上，於90 ℃下以3 ㎏/cm2壓力持壓20分鐘後，再利用含氟高分子FOTS修飾後可得水接觸角於奈米氧化鋅方面可以得到水接觸角為139.2°；添加奈米雲母可以得到接觸角為135.2°的表面。沉積法方面，於壓印出的圖案表面上沉積奈米四氧化三鐵以及修飾過的奈米雲母，再利用FOTS修飾表面後，奈米四氧化三鐵沈積表面的水接觸角可以達到151.9°，而奈米雲母表面可達到159.4°。綜合研究結果，以奈米氧化鐵、奈米氧化鋅、奈米雲母分別作為零維、一維及二維的奈米材料，並結合奈米壓印的方法，將無機與有機材料作混合以提升只有有機表面時的性質；並藉由表面改質的技術降低材料表面能，對於表面的疏水性質都能夠有顯著的提升。 In order to fabricate a hydrophobic organic/inorganic composite surface to modify the material surface, the nanoimprint technique were accessibly employed to corporate polymer matrix (epoxy resin or poly(methyl methacrylate)) and inorganic nanomaterials (Fe3O4 nanoiparticles, ZnO nanotube, or nanomica) to form the nanostructured surfaces. There were three methods utilizing in the nanofabrication: solvent-assisting, mixing and deposition methods. The composite nanopatterns were then deposited by a fluoroalkylsilane (FOTS) to decrease the surface energy. All the surfaces were inspected by SEM and optical microscope to observe their nanostructures and morphologies. The contact angle meter was used to measure the water contact angles of samples. For imprint by the mixing method, the nanomaterials were mixed with epoxyresin or PMMA with different ratios, and then imprinted and shaping under 3㎏/cm2 of pressurization at 120 ℃ for 20 min. A nanopattern with composite materials were obtained after demolding and coated with FOTS molecules. 1 wt% of nanomica addition was found to display 148.2° of water contact angle.
