Abstract:	在本研究中我們在玻璃基材上製作出一個透明且易潔、高硬度且耐磨的表面塗層。我們利用氧化鋯具有透明且高硬度的特色，配置了一系列可以在尋常環境下操作的氧化鋯塗料。然後在玻璃基材浸鍍出10~100奈米的透明薄膜。 450oC燒結後，此鍍層擁有接近19Gpa的硬度，可以承受鋼絲絨多次的摩擦。我們用原子力顯微鏡測量樣品的表面粗糙度並與耐磨耗性能做關聯。之後將磷酯類分子(alkyl phosphate)與二甲基矽酮 (PDMS)對氧化鋯表面進行改質，形成了對水滴及油滴均低滯留的表面，由而達到易潔的特性。最後，利用水平摩擦試驗機與奈米壓痕硬度機對樣品進行耐磨性及硬度的測量。 ;An air stable zirconium sol was developed that produces a transparent and hard zirconium film on glass substrates by dip-coating method. A film with barely 10~20 nm thickness showed nearly 19Gpa indentation hardness after heat-treated at 450oC and withstood several hundred cycles of scratching with steel wool under load. We then proposed a relationship between the hardness, wear-resistance, and the roughness measured by AFM. Further modification of the wear-resistant film with alkyl phosphate or PDMS leads to a hydrophobic surface showing very small contact angle hysteresis to both water and hexadecane, thereby becomes easy-cleaning. The durability of the surface was confirmed by the boil-water test, the cross-cut test, and further by the steel wool scratch test. The best product we obtained could withstand 900 cycles of steel wool scratch under 1kg/1cm2 load and still maintain hydrophobic with low contact angle hysteresis for water and hexadecane.
