碩士 === 明道大學 === 材料科學與工程學系碩士班 === 101 === In this study, Nano-SiO2 and Methacrylate (MMA) were formed the SiO2/PMMA nanocomposites by in situ polymerization, and this nanocomposites was coated the glass substrate by coating rod to form a SiO2/PMMA thermal curing monolayer. We controlled the amount of addition, including unmodified Nano- SiO2 and modified Nano- SiO2 to discuss thermal curing monolayer of the SiO2/PMMA resulting from different aspects of the effect. Described as follows：The phenomenon of thermal degradation by TGA was analysis；The mechanical property of hardness was tested by pencil；The property of adhesion was tested by Cross-cut tester；The light transmittance was tested by UV-Vis Spectroscopy. In addition, FTIR was employed to determine whether silane coupling agents react with Nano- SiO2. The morphology of nanoparticles status including unmodified Nano-SiO2 and modified Nano-SiO2 by SEM was observed. In the results, silane coupling agent MPTS was successful reacted with surface of Nano-SiO2. Additionally, the hardness and adhesion of the SiO2/PMMA thermal curing monolayer could improve because the addition of unmodified Nano-SiO2.
