Abstract:	本研究旨在製備不飽和聚酯/奈米鈦奈米複合材料，並檢測其物理性質、機械性質、電性質、光學性質與動態機械性質。本實驗使用矽烷偶合劑（MPS）接枝於奈米鈦表面進行改質。用以不飽和聚酯(UP)添加Ti和MPS-m-Ti奈米複合材料的製備與不同的成份克數(每100克的樹脂所含該之成分克數)。探討不同成份克數的Ti和MPS-m-Ti對不飽和聚酯奈米複合材料的形態學(FT-IR、SEM、TEM及XRD)、物理性質(密度、空孔率及接觸角)、機械性質(硬度、耐磨耗指數、抗折強度、抗張強度及耐衝擊強度)、熱性質(TGA、CTE、HDT及VST)、電性質(介電常數)、光學性質(透光率)及動態熱機械性質(DMA)之性能和影響的差異程度。實驗結果得知，經由TGA、FT-IR、XRD及XPS測試，可以證明矽烷偶合劑接枝的成功，並經由在粒徑分析下，能保有補強材的尺寸在奈米等級。在不飽和聚酯/奈米鈦奈米複合材料的添加Ti和MPS-m-Ti的部分，結構與形態學在SEM圖得知添加Ti和MPS-m-Ti可使表面結構從原來的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Ti或MPS-m-Ti，其強度都是下降；在熱性質，耐熱性提高效果更加顯著；在電性質方面，隨著Ti和MPS-m-Ti添加，介電常數有提升的效果；光學性質的透光率影響，添加Ti與MPS-m-Ti的含量越多，會使其透光度下降，反之吸光度有良好的提升作用。 This project object is to research the unsaturated polyester / nano titanium 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 titanium surface modification. For unsaturated polyester (UP) Add prepared Ti and MPS-m-Ti 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 Ti and MPS-m-Ti nanometer morphology of unsaturated polyester composites (FT-IR, SEM, TEM and XRD), physical properties (density, porosity and contact angle), mechanical properties (hardness, abrasion index, flexural strength, tensile strength and impact strength), thermal properties (TGA, CTE, HDT and VST), electrical properties (dielectric constant), the optical properties (transmittance) and the degree of difference between the dynamic mechanical properties (DMA) of the performance and impact. The experimental results that, by TGA, FT-IR, XRD and XPS 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 polyester / nm nm adding Ti and Ti MPS-m-Ti part of the composite material, structure and morphology in SEM image that the addition of Ti and MPS-m-Ti 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 Ti or MPS-m-Ti, its strength is decreased; thermal properties, heat resistance improving effect is more significant; in terms of electrical properties, with Ti and MPS-m-Ti Add permittivity have to enhance the effect; transmittance affect optical properties, add more content Ti and MPS-m-Ti, and will make it light transmission decreased, whereas the absorbance of a good promotion effect.
