碩士 === 國立交通大學 === 平面顯示技術碩士學位學程 === 105 === In this paper, we use inorganic thermal conductivity materials (ie, boron nitride BN) for (-C = C-) functional inorganic surface modification, the polymer silicone materials mixed with different sizes and proportions of inorganic thermal materials and different proportions (TiO2) powder, and the polymer composite samples were cured at 150 ° C for 0.5 hour, and the reflectivity of the polymer composites was discussed and studied. Through the modulation of the above parameters, coupled with the use of UV-vis spectral measurement instruments to measure different formulations of polymer composites we can obtain in the visible wavelength range (300 ~ 800nm) reflectivity of the high and low trends and explore the following changes: 1)Effect of boron nitride thermal powder (particle size) on the thermal conductivity and reflectivity of polymer composites. 2)Effect of Titanium Dioxide Reflective Powder Addition on thermal Conductivity and Reflectance of Polymer Composites. 3)Relationship between heat transfer performance and reflectivity of non-surface modified boron nitride thermal powder and titanium dioxide reflective powder blended on polymer composites. 4)Relationship between heat transfer performance and reflectivity of surface modified boron nitride thermal powder and titanium dioxide reflective powder blended on polymer composites.
