    摘要: 本研究利用溶膠-凝膠法在室溫下合成中空二氧化矽奈米粒子，粒徑約100 nm且進行表面改質。改質分成兩種方式，(I) 3-(三甲氧基甲矽烷基)丙基丙烯酸酯及氟化矽烷共同改質中空二氧化矽奈米粒子；(II)六甲基二矽氮烷改質中空二氧化矽奈米粒子。在方法(I)中，壓克力單體與中空二氧化矽奈米粒子，在PMMA基板上經由旋轉塗佈成膜再進行紫外光曝光，中空二氧化矽奈米粒和壓克力樹酯產生共價鍵結完成複合塗膜。中空二氧化矽奈米粒子與氟化矽烷莫耳比4.5 : 0.2，接觸角109o，在波長380~760 nm平均穿透率99.1%。在方法(II)中，PMMA基板上浸塗一層共聚物poly(MMA-co-MA)，接著浸塗上中空二氧化矽奈米粒子。塗膜接觸角129o、穿透率86%、附著度5B。
    In this study, ~100 nm spherical hollow silica nanoparticles were synthesized by the sol-gel method at room temperature, and were surface-modifyed. The modification was divided into two parts: (I) 3-(trimethoxysilyl)propylmethacrylate (MSMA) and 1H, 1H, 2H, 2H-perfluorooctyltrimethoxysilane co-modified hollow silica nanoparticles; (II) hexamethyldisilazane (HMDS) modified hollow silica nanoparticles. In the method (I), the composite coatings were prepared using acrylic monomer and hollow silica nanoparticles via spin coating on the PMMA substrate followed by UV-curing. The hollow silica nanoparticles and the acrylic resin have covalent bondings. The contact angle of the coating (SiO2 : fluorosilane = 4.5 : 0.2) was 109o, and average transmittance was 99.1% in the wavelength range of 380 – 760 nm. In the method (II), the poly(methylmethacrylate-co-methacrylate). was dipped on the PMMA substrate followed by dip coating of the sol of hollow silica nanoparticles. The contact angle of 129o, the average transmittance of 86%, and adhesion of 5B of the coating were obtained.
