dc.description.abstract蓮花效應是一個有趣的自然現象並已引起廣泛的研究,如何製作出如同蓮葉表面有自潔效果的材料是個重要的課題。在本論文是利用 聚亞醯胺作為基底材料,將合成出的 α,ω-aminopropylpolydimethylsiloxane (APPS)與氟矽烷 Tridecafluoro-1,1,2,2,-tetrahydrooctyl-1-triethoxylsilane(FAS-13)摻雜進聚亞醯胺,來提升材料的疏水性,並利用奈米壓印使表面形成奈米結構,使表面達到超疏水效果。本研究是採用含氟的雙胺或雙酸酐單體,來合成一系列的聚亞醯胺矽烷/FAS-13 混成薄膜,並探討APPS與FAS-13 的摻雜對材料特性的影響。經過IR 分析,我們成功地製備\出聚亞醯胺矽烷/FAS-13 混成薄膜,並對其熱性質、光學性質及疏水性進行分析後我們得知,其熱裂解溫度可達到490℃以上,在可見光區域的穿透度可達80%以上,接觸角則可從80°提升至110°,證實藉由APPS 及FAS-13 的摻雜,我們成功地製備出高疏水性的混成薄膜。 在本實驗中亦利用陽極氧化鋁模版,對聚亞醯胺矽烷/FAS-13 混 成薄膜進行壓印來製作奈米結構,並利用SEM 及AFM 來觀察分析。 經由分析,我們成功地在聚亞醯胺矽烷/FAS-13 混成薄膜表面製作出 奈米結構,其直徑約為70~100 nm,長度約為100 nm,根據理論分析,我們所製備的結構可使得材料接觸角達到150°以上,達到超疏水的效 果。zh_TW
dc.description.abstract“Lotus effect” is an interesting phenomenon in nature and has been widely studied for many years. How to fabricate materials with“self-cleaning”property like lotus leaves is well concerned. In this paper,we dope two different kinds of siloxane ,α,ω-aminopropylpolydimethylsiloxane (APPS) and fluoroalkylsilane(Tridecafluoro-1,1,2,2,-tetrahydrooctyl-1-triethoxylsilane,FAS-13), into polyimide to improve the hydrophobicity of the material. We also empolyee AAO template to take nanoprinting procedure on the film surface to make nanostructures , in order to achieve superhydrophobicity.The fluoride-containing diamine or dianhydride is chosen to synthesis series of PIS/FAS-13 hybrid films. PIS/FAS-13 hybrid films are successfully fabricated by FTIR analysis. Good thermal stability (above 490℃) and light transmittance ( above 80%) are retained and water contact angle increases from 80° to 110°, indicate that the hydrophobicity is greatly improved after doping. Besides, polyimide hybrid films with well-arrayed nanrostructures on them were successfully fabricated by utilizing AAO template nanopriting. In SEM and AFM amages, nanorods with diameter from 70 to 100 nm are observed and their height are about 100 nm. According to the theory, these nanostructure can make PIS/FAS-13 hybrid films achieve superhydrophobicity since water contact angle is above 150°.en_US
