本研究致力於模仿自然界植物表面的疏液性質，包含玫瑰花瓣表面的高黏著特性、蓮葉表面的超疏水自潔特性，及豬籠草唇的滑溜特性。以雙尺寸SiO2奈米粒子 (7/22nm) 作為材料，利用靜電逐層組裝方式製備 SiO2奈米粒子薄膜，並在組裝程序中引入類乙醇體陰陽離子液胞作為模板，透過控制層數及模板比例，再經矽烷疏水化後，創造可調控黏著性的表面，並應用於微液滴的無耗損傳輸。此外，更進一步，將潤滑液體 (Fomblin® Y) 引入前述製備的超疏水SiO2薄膜孔洞內，創造出穩定且具備高穿透度的全疏滑溜表面。
研究結果顯示，利用控制層數及模板比例可有效的改變表面型態與粗糙度，產生包括高黏著性 (如玫瑰花瓣) 及低黏著性 (如蓮葉) 的表面。將不同黏著性表面應用於微液滴傳輸，並建立無耗損微液滴傳輸之準則 (後退接觸角, θR ≥ 106o 及 遲滯接觸角, θH ≤ 59o)。此外，最適化全疏滑溜表面具有94.6%的平均穿透度，且對於七種測試液體(表面張力由72.8mN/m至18.6mN/m)，皆具有全疏滑溜性質 (傾斜角, SA≤ 10o)。

This work aims at developing biomimic liquid-repellent surfaces. Including high adhesion surface, low adhesion superhydrophobic surface and slippery surface mimic rose petal, lotus leaf and nepenthes pitcher plant respectively. Surfaces with different roughness were fabricated by assembling silica nanoparticles and sacrificial ethosome-like catanionic vesicle template on glass substrates. Electrostatic layer-by-layer (ELbL) assembly process was used. Fraction of vesicle in silica nanoparticle suspension and number of deposition layer are main control variables. After modification with a perfluorosilane, a variety of water adhesion properties created. Water microdroplet transport from bottom surfaces with different adhesion to a top surface with the highest adhesion was then systematically investigated. Moreover, stable and highly transparent slippery surface can be achieved by infusing fluorinated lubricant Fomblin® Y into the porous silanized nanoparticulate thin film. The results showed that different rough surfaces with tunable adhesion can be created. Including high adhesion surfaces like rose petal, low adhesion surfaces like lotus leaf. Using those surfaces on microdroplet transport, criteria of no-loss microdroplet transport (θR ≥ 106o and θH ≤ 59o) were finally proposed based on the adhesion properties. Moreover, stable and highly transparent slippery surfaces can be prepared. The optimized slippery surface exhibited highly transparency (average transmittance = 94.6%) and liquid repellency against seven pure liquid with surface tension from 72.8mN/m to 18.6mN/m.
