| Summary: | 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 === 103 === 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.
