| 摘要: | 本研究主旨在於製備具高介電常數及高性能之不飽和聚酯樹脂/奈米鈦酸鋇(BaTiO3)複合材料，並檢測其熱性質、機械性質、物理性質與電性質。本實驗使用矽烷偶合劑（MPS）接枝於BaTiO3之表面進行改質。用不飽和聚酯 (UP) 樹脂添加不同的成份克數(每100克的樹脂所含該之成份克數)的BaTiO3和MPS-m-BaTiO3製備成奈米複合材料。
探討在不同成份克數之BaTiO3和MPS-m-BaTiO3對不飽和聚脂樹脂奈米複合材料的形態學(粒徑分析、FT-IR、SEM、XRD、Raman)、物理性質(密度、空孔率)、機械性質(硬度、耐磨耗指數、抗折測試、抗張測試及耐衝擊測試)、熱性質(TGA、CTE、HDT及VST)、電性質(介電常數)及動態熱機械性質(DMA)之性能和影響的差異程度。
由實驗結果可得知，經由TGA、FT-IR及XRD測試，可以證明矽烷偶合劑接枝是否成功，並經由粒徑分析下，能保有補強材的尺寸仍在奈米等級。
在不飽和聚脂樹脂/奈米鈦酸鋇奈米複合材料添加BaTiO3和MPS-m-BaTiO3的部分，結構與形態學在SEM圖可得知在添加BaTiO3與MPS-m-BaTiO3可使表面結構從原來多孔洞變為較平滑的表面；物理性質的測試，密度與空孔率上升；在機械性質測試結果，硬度與磨耗指數，皆為上升。則抗折與抗張的測試中，添加BaTiO3或MPS-m-BaTiO3，其強度與模數皆有上升趨勢；在熱性質，耐熱性提高效果更加顯著。在電性質方面，隨著BaTiO3和MPS-m- BaTiO3添加，介電常數有提升的效果。
This project object is to research the unsaturated high dielectric constant and high performance of the Preparation of Unsaturated Polyester Resin / barium titanate nanocomposites and determine properties about physical, mechanical properties, electrical properties,optical properties and dynamic mechanical properties. In this study, using 3-(Trimethoxysilyl) propyl methacrylate (MPS) grafted nano barium titanate surface modification. For unsaturated UP Add prepared BaTiO3 and MPS-m-BaTiO3 Nanocomposites with a different number of grams of composition (per 100 grams of resin contained in the composition of the number of grams). Explore the different components of the number of grams of BaTiO3 and MPS-m-BaTiO3 nanometer morphology of unsaturated UP composites (Particle, FT-IR, SEM, XRD, Raman), physical properties (density, porosity), mechanical properties (hardness, abrasion index, flexural strength, tensile strength and impact strength), thermal properties (TGA, CTE, HDT, VST), electrical properties (dielectric constant)and the degree of difference between the dynamic mechanical properties (DMA) of the performance and impact.
The experimental results that, by TGA,XRD and FT-IR and testing can prove the success of silane coupling agent grafted via at particle size analysis, to retain the size of the reinforcing material in nano levels. Unsaturated UP / barium titanate adding BaTiO3 and MPS-m-BaTiO3 part of the composite material, structure and morphology in SEM image that the addition of BaTiO3 and MPS-m-BaTiO3 allows more surface structures from the original hole into a smoother surface； a test of physical properties, effectively increasing； in mechanical properties test results, hardness and abrasion index, are all rising. The bending and tensile test, adding BaTiO3 or MPS-m-BaTiO3, its strength is rised； thermal properties, heat resistance improving effect is more significant； in terms of electrical properties, with BaTiO3 and MPS-m-BaTiO3 Add permittivity have to enhance the effect. |
