摘要

本論文以總體聚合法來製備聚甲基丙烯酸甲酯／蒙脫土和聚甲基丙烯酸甲酯／改質蒙脫土奈米複合材料，將未改質蒙脫土和改質蒙脫土加入聚甲基丙烯酸甲酯基材中，強力攪拌分散並進行自由基聚合反應，並探討此兩類奈米複合材料之機械性質和熱性質。奈米複合材料之靜態機械性質探討包括抗折強度與模數、抗張強度與模數和衝擊強度；動態機械性質探討包括動態儲存模數；熱性質探討包括示差掃描卡計法(DSC)和熱重量損失法(TGA)。

This paper researched the mechanical and thermal properties of poly (methyl methacrylate) (PMMA)/montmorillonite (MMT) and PMMA/organic modified montmorillonite (OMMT) nanocomposites. PMMA/MMT and PMMA/OMMT nanocomposites have been synthesized by bulk polymerization. The particles of MMT and OMMT were dispersed using forced agitation and the composites were polymerized using free radical polymerization. The comparison of the addition MMT and OMMT also have been investigated in this experiment. The effects on the properties of experiment results have been found by static mechanical tests based on flexural strength and modulus, tensile strength and modulus, and impact strength. The dynamic mechanical analysis (DMA) based on dynamic storage modulus (E'). The thermal analysis based on differential scanning calorimetry (DSC) and thermogravimetric analysis (TGA).
