  • 本研究探討不同結構對於無機抗反射薄膜之光學與機械特性影響,目的是要開發具高透光、高硬度之抗反射塗料可應用於顯示器玻璃上。
    利用溶膠凝膠法,我們將不同前驅物,以酸性或鹼性條件下,透過參數調整,可合成出不同薄膜結構之抗反射塗料,該結構分別為多孔性奈米球、薄膜或者多孔性奈米球混入薄膜型;這些不同形式的藥水,都以浸塗方式讓材料附著在玻璃兩側表面上,再以高溫進行烘烤,目的去除溶劑與增加與玻璃附著,最後以各式儀器進行製程條件的分析。
    從結果可知,以抗反射效果為多孔性奈米球最好,但機械性奈米球最差,而薄膜穿透度雖遜色多孔性奈米球,但其機械性質為最佳,故若要有良好的透光與優異的機械特性,勢必需要權衡。

    This study investigates the effects of different structures on the optical and mechanical properties of inorganic antireflective films. The aim is to develop antireflective coatings with high transmittance and high hardness that can be applied to the display glass. Using the sol-gel method, we can synthesize antireflective coating solution with different precursor under the acidic or alkaline conditions, which can fabricate different structure of film by dip coating process. And then baking at high temperature, the purpose of removing the solvent and increase with the glass attached. From the results, it can be seen that the antireflection effect is the best for the porous nanoparticles, but the mechanical nanoparticles are the worst, and the membrane penetrability is less porous than the porous nanoparticles, but its mechanical properties are the best. It is bound to need to weigh how antireflective films equipped with good light transmission and excellent mechanical properties.
