    Abstract: 本論文主要探討自然界中Papilio blumei蝴蝶其翅膀上綠色部位之疏水性,造成疏水性的原因,是因為表面的孔洞由微米等級造成水滴不易與表面接觸,本文利用奈米壓印法複製蝴蝶表面凹洞,使薄膜也具有疏水性。
    首先,利用聚二甲基矽氧烷(PDMS)複製蝴蝶表面凹洞,此時PDMS 是負結構;再來塗佈一層薄膜;最後是把負結構的PDMS壓印製薄膜上,使之為正結構。
    而最後的薄膜壓印上結構後,接觸角從原本的75.03o增加至102.99o,亦即薄膜由屬於親水性轉變為疏水性。; In this study, we studied the hydrophobic characteristic of Papilio blumei butterfly scale, especially in green part on the butterfly wing. The reason for hydrophobic characteristic of this butterfly wing is that the surface is composed of concaves with few micrometer which a drop of water can't contact the surface easily. Nanoimprint technology has been applied to reproduce the surface structure (concaves) of butterfly wing so that the thin film is hydrophobic.
    The first step in the process, we use PDMS to mimic the surface of butterfly wing (concaves). The PDMS is a negative structure. In the second step, we make the thin film by spin coating. The last step is that use PDMS to imprint a thin film, let the thin film is with positive structure.
    Owing to the surface of thin film with concave structure, contact angle of structure-thin film is increased from 75.03o to 102.99o.
