碩士 === 國立臺北科技大學 === 化學工程研究所 === 98 === The aim of this project is to develop new type rare earth metals surfaceant. Firstly, oleic acid and the other three oxides (Y2O3, TiO2, Al2O3) to do synthesis.By Frustrated Total Internal Reflection (FTIR) and 1H-NMR are to decide synthesis. The results only oleic acid and oleic acid synthesized [CH3-(CH2)7-CH=CH-(CH2)7-COO]3Y surfactant. Different percentage of surfaceant into polymer (Polyporopylene,Nylon) and mineral (Mica) or 200~300nm Titania that they are blending.We can obtain Polyporopylene and 0.3~1.5% mica/[CH3-(CH2)7-CH=CH-(CH2)7-COO]3Y dispersant and Nylon and 0.3~1.5% TiO2/[CH3-(CH2)7-CH=CH-(CH2)7-COO]3Y dispersant.After that,they are injection molding. And thermal conductivity measurements and SEM observation to TiO2 in Nylon and the dispersion of mica in the PP case.When we under appropriate conditions.The measured thermal conductivity of the blending materials. Polyporopylene/mica with 1.5% [CH3-(CH2)7-CH=CH-(CH2)7-COO]3Y dispersant and Nylon with 1.2% TiO2/[CH3-(CH2)7-CH=CH-(CH2)7-COO]3Y dispersant of the thermal conductivity in the best.
