本研究將親水性二氧化矽,利用溶膠凝膠法,將表面改質形成三甲基矽氧烷,製備成疏水性奈米二氧化矽,並將之摻混於含氟丙烯酸酯等油相單體中,藉由奈米二氧化矽製造粗糙度,氟提供薄膜低表面自由能,形成蓮花效應之表面結構,製備具有疏水性、疏油性的含氟丙烯酸系列奈米複材薄膜。利用FT-IR、1H-NMR鑑定奈米二氧化矽結構;並探討變因於摻混二氧化矽含量多寡及稀釋成不同的濃度,藉由高速旋轉塗佈,將所製備出薄膜測試其親疏水性質、可見光穿透率以及薄膜表面性質、粗糙度、耐熱性鑑定。
In this study, the fluoroacrylate nanocomposite films with super hydro-oleophobic property will be prepared by importing fluorocarbon functional group into the side chain of acrylic ester. These modified copolymers maintain the acrylate characteristics, and effectively improve the chemical resistance, weather resistance, stain resistance, and hydro-oleophobic property. Besides, hydrophobic silica will be prepared by modifying different nanoparticles of silica with silane coupling agent. This hydrophobic silica will then be mixed uniformly with fluoroacrylate monomers to increase the surface roughness, and to prepare the super-hydrophobic, oleophobic, and self-cleaning film.
