本研究致力於發展模仿植物表面的疏液性質，製備出具備如同豬籠草唇上滑溜特性的表面。以添加氟烷基矽烷(FAS-13)的含氟共聚高分子　(Poly(vinylidene fluoride-co-hexafluoropropylene), PVDF-HFP)以及經過矽烷疏水化後的SiO2奈米粒子(HM-SiNPs)做為主要材料，並利用刮刀塗佈方式製備奈米複合薄膜。接著將極低表面張力的Fomblin® Y引入前述製備的粗糙結構中，創造出具有穩定且全疏滑溜的表面。
研究結果顯示，利用控制PVDF-HFP及HM-SiNPs之比例可有效改變薄膜的表面型態與粗糙度，此外疏水性也會隨著HM-SiNPs的比例提升而增加，產生一疏水且具高黏著力的表面，就如同玫瑰花瓣表面的特性。接著利用Fomblin® Y注入表面之後所形成的滑溜表面在PVDF-HFP及HM-SiNPs之比值小於1的情況下，對於七種測試液體(表面張力由72.8mN/m至18.6mN/m) 都會從滑溜薄膜上滑落，皆具有全疏滑溜性質 (傾斜角, SA≤ 10o)。滑溜薄膜在時間的持久性測試具備一定程度的穩定性。由於其易於製備的優點，應用於不同基板的表面也可以具備良好的全疏滑溜特性。

In this work, biomimic liquid-repellent surfaces which has slippery property like nepenthes pitcher plant was demonstrate. PVDF-HFP mixed with 1H,1H,2H,2H-perfluorooctyltriethoxysilane (FAS-13) and hydrophobically-modified silica nanoparticles (HM-SiNPs) were used for the main material. The nanocomposite film was fabricated by blade coating. Furthermore, stable and slippery surface can be fabricated by infusing perfluorinated lubricating liquid, Fomblin® Y, which has extremely low surface tension into the rough nanocomposite thin films. The results showed that the morphology and roughness can be control by adjusting the ratio of PVDF-HFP and hydrophobically-modified silica nanoparticles. The nanocomposite surface has the hydrophobic and high adhesive properties like rose petal. After infusing the Fomblin® Y into the rough nanocomposite thin film, the slippery surface which the ratio of PVDF-HFP and HM-SiNPs was less than 1 exhibited highly liquid repellency against seven pure liquids (water, ethylene glycol, hexadecane, pentadecane, nonane, octane, and haxane) with surface tension from 72.8 mN/m to 18.6 mN/m. In persistence test for time and resistance test for shear force, the slippery property still can be kept. Because of the advantage for facile fabrication, the nanocomposite thin film could apply in different kinds of substrates and still possess great slippery properties. In addition, we also demonstrated that the SLIPSs exhibit ice-repellent properties after freezing in refrigerator for one hour.
