碩士 === 中國文化大學 === 化學工程與材料工程學系奈米材料碩士班 === 102 === 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.
