摘要:	本論文旨在討論不飽和聚酯樹酯（UP）與奈米二氧化鈦形成之奈米複合材料之加工製程、機械性質與熱性質之研究。實驗用3-甲基丙烯酸基丙基三甲氧基矽烷（MPS）和四乙氧基矽烷（TEOS）改質奈米二氧化鈦。聚合時以不同含量重量百分比之改質奈米二氧化鈦與未改質奈米二氧化鈦進行聚合。探討不同重量百分比不飽和聚酯樹脂/奈米二氧化鈦的形態學( FT-IR、XRD、粒徑分析、SEM、XPS )，物理性質( 密度，空孔率，接觸角 )，機械性質( 硬度，抗折試驗，抗張試驗，衝擊強度試驗，耐磨耗指數，DMA ) ，熱性質(TGA、HDT、Vicat )，UP樹脂性能和完善的差異程度。實驗結果得知，經由FT-IR與XPS測試，發現UP/奈米氧化鈦奈米複合材料的改質後官能基，粒徑分析中奈米氧化鈦（未改質和改質）都在奈米規範；在XRD測試可以看到晶相結構；在FE-SEM具有的良好分散性能。添加奈米二氧化鈦的物理性質的測試，有效提升；在機械性質測試結果，拉力和衝擊皆隨著奈米二氧化鈦的添加而下降，；在熱性質，HDT和維卡耐熱性提高效果更加顯著的增加10℃以上。 This paper aims to discuss the formation of Unsaturated polyester (UP)resin nano and nano titanium oxide composites machining processes, mechanical properties and thermal properties study.. The research used 3-methacryloxy-propyl-trimethoxysilane (MPS) and Tetraethyl orthosilicate (TEOS) to modify surface of nano titanium oxide . Aggregation of different weight percent content of the unmodified polymer nano titanium oxide (include non-modify and modify) powder After forming the different levels of weight percent of the UP resin/nano titanium oxide morphology (FT-IR, Particle, XRD, FE-SEM, XPS), physical properties (Density, Contact Angle , Void content), mechanical properties (Hardness, Flexural test, Tensile test, Impact strength, Wearing), thermal properties (TGA, HDT, Vicat) for UP resin properties and improve the degree of difference. Experimental results show, by FT-IR, the crystal structure of UP / nano titanium oxide nano composites was determined; in particle size analysis show nano titanium oxide (include non-modify and modify) are both in nano specification; at XRD and XPS test can see nano composites contains nano titanium oxide; Good dispersion can be seen in FE-SEM. Adding nano titanium oxide powder does effectively enhance in the physical properties test; In the mechanical properties test results showed that the tensile and impact are down,when titanium oxide are added. In the thermal properties, heat resistance of HDT and Vicat to enhance effect even more pronounced with the increase of nano titanium oxide added.
