油酸釔分散劑應用於高分子複合材料之研究

本研究之目的是開發新型稀土金屬分散劑應用於高分子複合材料，首先利用油酸與其他三種不同氧化物(Y2O3、TiO2、Al2O3)做合成反應，經由紅外線光譜儀(FT-IR)、1H-NMR等來確定，實驗結果唯有油酸與Y2O3合成為油酸釔。再依不同比例的分散劑添加於雲母粉及二氧化鈦和高分子中，進行混鍊，經過這樣程序，可以獲得含有Polypropylene與0.3~1.5%雲母粉/油酸釔分散劑及Nylon與0.3~1.5%TiO2/油酸釔分散劑之混鍊物，再經破碎處理及射出成型，則可得上述之膜型，測得熱傳導係數，且最後利用SEM觀察TiO2於Nylon及雲母粉於Polypropylene的分散情形。當我們在適當條件下，所測得混鍊物之熱傳導係數，分別以Nylon與1.2%TiO2/油酸釔的混鏈及Polypropylene與1.5%雲母粉/油酸釔混鏈的熱傳導係數最佳。

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.
