摘要

本文主要著重在利用溶膠-凝膠法改質之奈米材料，複合而成塗料或樹脂，藉以提升其物理性質與光學性質。此製程具有製程溫度低、可選用之反應物種類選擇性大、可大面積基材被覆之可能性高…等優點，再加上設備簡易且成本低，目前已被廣泛應用於許多商品。溶膠－凝膠法藉由金屬烷氧化物當前驅物做起始反應，並可與有機物做結合成為有機／無機的混成物，因應不同需求可應用並製備出多功能性的塗層與複合材料，如易潔防污、高硬度、抗反射、抗指紋、高折射率、低折射率…等功能。不但有助於提升複材本身之功能性與價值性，同時有助於產品使用的適用性與多樣性。

The article focuses on the nanocomposite resins and coatings via a sol-gel process prepared nano materials. The process possesses many advantages including low synthesis temperature, large area coating possibility, low equipment cost and has been applied in many commercial products. It uses metal alkoxides as precursors and involves the evolution of inorganic networks through the formation of a colloidal suspension (sol) and gelation of the sol to form a network in a continuous liquid phase (gel). Furthermore, the combination of organic and inorganic hybrid components could match various applications and create many functions including easy clean, hard-coating, anti-reflection, anti-fingerprint, high refractive index and low refractive index etc. It increases the physical and optical performances to benefit the applications and varieties.
