中文摘要 本文研究討論自然界植物葉片表面結構與其疏水特性的關係,並使用物理方法將葉子表面之微結構,複製到聚二甲基矽氧烷(PDMS,Poly dimethyl-siloxane)上,得到一表面疏水膜,比較與原葉片之差異並探討其結構表面與疏水特性的關係。實驗結果顯示疏水性較佳的葉片分別為蓮葉正面的突點狀結構及黃槿背面、芙蓉和艾草的立體結構,其接觸角分別為150°、135°、145°和130°。在一次膜的接觸角量測上並無明顯的疏水性變化。疏水材質的PDMS二次膜再配合有明顯結構的葉片表面,讓其疏水表面更加疏水,其接觸角到達150°。
英文摘要 This research studies the relationship between the surface structure of natural leaves and their hydrophobic characteristics, and uses a physical method to replicate the microtextures of leaf surfaces on PDMS to get a hydrophobic mold. Their surface morphology of the natural leaves and replicate ones is examined and the relationship of different surface structures and their hydrophobic characteristics are deduced. Better hydrophobic properties are seen on the lotus leave which has papilla cells and the hibiscus and the wormwood leaves with convex cells. However, no obvious difference in contact angle of negative mode is observed. The papilla cells structure with hydrophobic material at positive mode makes hydrophobic surfaces more hydrophobic.
