本文研究使用物理方法,將蒸過的葉子表面之微結構,複製到聚二甲基矽氧烷(PDMS,Poly dimethyl-siloxane)後,得到一表面疏水膜及再經過反應式離子蝕刻(RIE,Reaction Ion Etching)改質成親水性表面,並比較兩者差異。經實驗試出最便利與最佳複製方式且複製出之蓮葉接觸角高達140°。再利用SEM(JSM-5600)量測複製後的PDMS表面結構尺度深寬比與表面微米結構形狀,並利用FTA100儀器量測接觸角來比較與實際葉片之接觸角度差異,再利用光學顯微鏡拍攝其活體影像來觀察其立體表面差異性,來比較複製成果。整體比較原本屬於疏水材質的PDMS與經過表面改質成親水材質的PDMS在經過葉片複製後其原本疏水結構與親水結構在不同親疏水PDMS上之比較,其複製結果顯示較疏水之結構配上疏水表面會更疏水;而較疏水表面配上親水表面會更親水。
This research uses a physical method to replicate the microtextures of leaf surfaces after steaming to PDMS to get a hydrophobic mold or through surface change of RIE to a hydrophilic mold and then compare their difference. The lotus leaf being tried can be duplicated to get contact angles up to 140 °.Surface features are explored by OM,SEM and FTA100 instruments. It show as a result that a hydrophobic mold match with a hydrophobic structure were increase hydrophobic. A hydrophobic mold match with a hydrophilic structure were increase hydrophilic.
