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 === 104 === This project object is to research the unsaturated high dielectric constant and high performance of the phenolic 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 phenolic resin (PF) 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 phenolic resin composites (FT-IR, SEM, TEM and XRD), physical properties (density, porosity), mechanical properties (hardness, abrasion index, flexural strength, tensile strength and impact strength), thermal properties (TGA, CTE, HDT and VST), electrical properties (dielectric constant)and the optical properties (transmittance). 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 phenolic resin / 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; transmittance affect optical properties, add more content BaTiO3 and MPS-m-BaTiO3, and will make it light transmission decreased, whereas the absorbance of a good promotion effect.
