本研究主要是探討奈米金屬氧化物和矽烷以溶凝膠(Sol-Gel)法合成有機-無機混成塗料。此一塗料可塗佈在各種塑膠表面而具有保護作用,同時具備抗磨、高硬度等性質,且與基材附著良好。
實驗的步驟為利用奈米氫氧化鋁(AlOOH)和具壓克力基矽烷 (MPTS)在高溫下進行水解縮和,而後以溶劑稀釋至固成分45wt%之溶膠。製備完成的溶膠可儲存30天以上而黏度維持穩定。此一溶膠加入UV起始劑及其他補助劑後配成塗料,以旋鍍或線棒方式塗佈於PC、PMMA、PVC板材和PET 膜(厚度38μm)等基材上,經UV光照射硬化後,以標準測試方法來檢測此塗佈層與塑膠基材的黏著性,抗磨性及硬度。測試結果發現此塗佈層完全不會剝落。並且經過研磨機上研磨500轉後,PC、PVC和PMMA的透光度只下降5∼10%;而PET 膜在研磨100轉後透光度僅下降2%。已達到實用規格要求。
This work describes the reaction of nanoscaled metal oxides and silane by the sol-gel process to make inorganic/organic hybrid coatings. These hybrid coatings are UV curable, hard, transparent and can improve the abrasion resistance of plastics ( eg. PC、PMMA、PVC and PET).
The nanoscaled boehmite particles and methacrylate functionalized silanes were used for the preparation of the UV curable hard coatings. After the hydrolysis and condensation of the methacryloxysilane in presence of the nanoparticles at high temperature, the sol was diluted with solvents. The solid content of this coating sol was 45wt% and it had a long pot life. The transparent coatings on plastics were produced by spin coating or wire bat and the coatings show good optical quality and excellent adhesion on plastics coated with primers.

The transparent coatings show good abrasion resistance after performing the Taber abrader test. After 500 abrasion cycles, haze values of the coating on PC、PVC、PMMA were 5~10% and for the coatings on PET film (38μm, thickness) the haze values were 2% after 100 cycles.
