| 摘要: | 本計畫旨在研究有機化奈米雲母/高分子樹脂之混成無機/有機奈米複合材料，探討此奈米複合材料之製備方法及其材料性質。利用奈米雲母之三度空間網狀結構與特有性質，如高強度、高剛性、耐熱性、耐燃性、耐磨耗、抗UV、抗氧化、抗靜電(或絕緣)、硬度佳、化學穩定性高、電絕緣性佳等特性，在混入高分子有機材料時，可以有效提升高分子樹脂之物理性質、機械性質、熱學性質、化學性質等功能，使得高分子樹脂應用更為廣泛。本計畫分三年執行，第一年利用熔融混煉插入法(Melt intercalation)製備奈米雲母/聚丙烯之奈米複合材料；第二年利用瞬時聚合插入法(In-situ polymerized intercalation)製備奈米雲母/環氧樹脂之奈米複合材料；第三年利用溶液插入法(Solution intercalation)製備奈米雲母/聚苯乙烯之奈米複合材料。探討各製備方法之加工變數，使用具有Methacrylic、Alkyl (第一年)、Epoxy、Amino (第二年)、Vinyl、Amino (第三年)官能基團之矽烷偶合劑對奈米雲母進行表面改質，使奈米雲母表面有機化，利用霍式紅外線光譜(FTIR)、拉曼光譜(Raman spectra)、電子能譜儀(XPS)與熱重量分析儀(TGA)來鑑定改質奈米雲母，並且使用雷射粒徑分析儀分析改質前後奈米雲母之粒徑大小分佈情形。利用X光繞射儀(XRD)分析奈米雲母/高分子樹脂奈米複合材料之微結構與結晶度變化，利用電子顯微鏡(SEM、TEM、AFM)觀察奈米雲母在高分子樹脂中之分散與結合情形之形態學。比較添加奈米雲母前後高分子樹脂之物理性質(密度、膨潤性質)、靜態機械性質(抗張強度與模數、抗折強度與模數、耐衝擊強度、硬度、耐磨耗)、動態機械性質(E’, E”, tan)、熱性質(HDT、Vicat、TGA、DSC、TMA、熔融指數)與化學性質(吸水性、耐候性、氣體滲透性)等，以提升高分子樹脂之性質。
