碩士 === 國立臺灣科技大學 === 纖維及高分子工程研究所 === 87 === An organic-inorganic hybrid materials have been prepared by incorporating poly(DGEBA-co-APTS-co-DER732) into the SiO2 glass network via the sol-gel approach .A polymer precursor was synthesized by copolymerization of diglycidyl ether of bisphenol A (DGEBA), DER-732, and 3-aminopropyl trimethoxysilane (APTS) to obtain the poly(DGEBA-co-APTS-co-DER-732).The characteristics and properties of the copolymer were characterized by FTIR, elemental analysis, differential scanning calorimetry, and thermogravimetric analysis. The precursor was then hydrolysed and co-codensated with tetraethoxysilane (TEOS) in tetrahydrofuran at room temperature to afford epoxy-SiO2 hybrid sol-gel materials having different SiO2 contents. The epoxy-SiO2 with different SiO2 content were used as fillers for dental composite resins. The effect of the epoxy-SiO2 hybrid materials on several mechanical properties and water absorption of the dental composites was investigated.
