    Abstract: 本文研究利用溶膠-凝膠技術,製備聚(醯胺-亞醯胺)混成材料。混合二胺4,4′-Diaminodiphenyl ether (ODA) 、二酸酐3,3′,4,4-Benzophenonetetracarboxylic dianhydride(BTDA)與Trimellitic anhydride chloride(TPCl),同時利用單官能胺基結構之3-Aminopropyltrimethoxysilane (APrTMOS) 為末端官能基,合成分子鏈長為5000及10000 g/mole和未控制分子鏈長之poly(amide-imide acid)寡聚合體溶液。poly(amide-imide acid)經水解/縮合反應後,獲得系列PI混成薄膜材料。由結果得知,在熱重分析(TGA)方面,PI混成薄膜於空氣下,皆顯示一階段的熱重損失,並且PI混成薄膜之5﹪重量損失,皆高於530℃,表示於空氣下維持優異的熱性質。在動態機械分析(DMA)方面,較短的網目分子鏈長(5000g/mole系列)皆比較長的網目分子鏈長(10000g/mole系列)有較高的儲存模數,並有較低的玻璃轉移溫度與damping強度。系列混成薄膜中以5000-PI-15- TPCl其儲存模數和玻璃轉移溫度最高,且damping的強度最低,表示添加APrTMOS及TPCl的PI混成薄膜具有較高的熱和機械性質。
