本研究利用溶膠-凝膠法製備聚碳酸酯/二氧化矽有機/無機混成奈米複合材料,並探討熱性質、機械性質、形態學和光學性質。對於CO2與Allyl Glycidyl Ether( AGE,屬軟鏈單體)及Cyclohexene Oxide( CHO,屬剛硬單體)共聚反應中,以Y(CF3CO2)3-Zn(Et)2-
Pyrogallol為最佳觸媒系統,其成份莫耳比例為[Zn(Et)2]/[Y(CF3CO2)3]為20,[Pyrogallol]/[ Zn(Et)2]為0.5。當共聚反應溫度為80℃、壓力為400psi、溶劑為1,3-dioxolane時為最佳操作條件。經此稀土族配位觸媒所合成之聚碳酸酯屬交替共聚型,其Carbonate Unit含量(fco2)為93%,玻璃轉移溫度為63℃,10%熱分解重量損失溫度為307℃。
利用所合成之聚碳酸酯側鏈之雙鍵和3-(Trimethoxysilyl)propyl
methacrylate(MSMA)在Benzoyl Peroxide(BPO)為起始劑下進行自由基反應,使聚碳酸酯側鏈上含有矽氧烷基以利進行後續之溶膠-凝膠實驗。此改質過後之聚碳酸酯經過1000℃高溫燒結可得其中之矽含量。此含矽之聚碳酸酯再和Tetraethoxysilane(TEOS)在酸性觸媒下和進行溶膠-凝膠方法合成出有機/無機混成奈米複合材料。
若所合成出的複材中含較多軟鏈基團時,隨著Si含量的上升,熱性質、抗張強度和抗張模數也隨之增加,但斷裂點伸長率則隨著Si含量上升而下降。對於含剛硬基團比例較高的複合材料,其Tg隨著Si含量上升,反而有下降的情況,此乃剛硬基團所造成的影響。透光度皆可維持在95%以上,顯示所合成出之複合材料為均ㄧ相材質,從SEM與Si-Mapping圖譜可顯示Silica顆粒分散效果佳且顆粒大小在100nm以下。
