本研究主要探討如何以二氧化矽為材料製備具雙疏特性之超滑表面，並比較以不同結構粗糙基底製成之超滑表面其滑動效能隨時間的變化。首先製備以二氧化矽為材料之粗糙表面並以改質劑Trichloro(1H,1H,2H,2H-perfluorooctyl)silane將碳氟鍵官能基嫁接於二氧化矽表面，使之成為具低表面能之粗糙結構，再灌入低表面能之潤滑劑(Perfluoropolyether, Solvay, Fomblin M03)製成超滑表面。
本研究以兩種方法製備不同結構之二氧化矽粗糙表面，第一種方法為二氧化矽粒子膠體溶液噴灑在塗佈於玻璃基板的矽膠層，以矽膠為黏著層黏著微米級二氧化矽粒子，經熱固化處理後得到具有二氧化矽粒子突起結構之粗糙表面，第二種方法為將二氧化矽前驅溶液經電紡絲法製備成二氧化矽之奈米纖維，並以此纖維交織構成的膜作為超滑表面之粗糙基底。
實驗結果顯示將低表面能潤滑劑填入粗糙結構便可製成超滑表面，使水珠能夠在3∘，油酸能夠在5∘的滑動角滑動。在水流沖刷測試上，對不同平均粒徑二氧化矽粒子所構成之超滑表面，較小粒徑二氧化矽有較佳耐沖刷效果；而對不同平均粗細纖維所構成之超滑表面，較細的纖維有較佳耐沖刷效果。兩方法製備之超滑表面，以纖維製成之超滑表面有較佳耐沖刷效果。故由本實驗結果可知，較小粗糙度及高孔隙特性的基底構成之超滑表面在水流沖刷下具有較佳的耐久性。

In this study, the water/oil-repellent Slippery Liquid Infused Porous Surface (SLIPS) with low sliding angle of water (<3∘) and oleic acid (<8∘) was fabricated by infusing the lubricant(Perfluoropolyether, Solvay, Fomblin M03) onto the fluorinated SiO2 textured substrates. The substrates were fabricated in two different ways. One is spraying the silica particle on the silicone gel and then curing the gel to bind the particle and form the texture substrate. Another method is fabricating the silica fiber mat by electrospinning as porous substrate. The substrates were modified by grafting the fluorinated coupling agent(Trichloro(1H,1H,2H,2H-perfluorooctyl)Silane) on the surface of SiO2 substrates. The lubricant was infused onto the modified textured substrate and form the SLIPS.
The effect of the underlying substrates on their abilities to retain the lubricant under water flow(34cm/min) was investigated. By comparing the sliding angle of water droplet(10µl) on the washed SLIPS, the substrates with smaller surface roughness and more pores provides larger capillary force to entrap the lubricant, leading to better durability under water flow system.
