中文摘要 | 本文以經有機改質之蒙脫土對鏈延長劑預聚合體進行插層反應,再與聚丁醚二醇及二苯甲基二異氰酸鹽所合成之聚氨基甲酸酯預聚合體行聚合反應,合成聚氨基甲酸酯/奈米黏土聚合體。經X光繞射測試得知本研究的確可以成功地達到插層的效果,尤其是在鏈延長劑預聚合體部分可看出層間距明顯改變。在機械性質方面,經黏土插層後之奈米複合材料其機械性質隨黏土含量提升前增加。此外在染色性方面,合成物之染著率會隨加入有機改質蒙脫土量之增加而下降,但其耐水洗堅牢度則可達4-5級。 |
英文摘要 | The article is using the polyurea prepolymer, which was synthesized from the extender (ethylene diamine or N-(2-hydroxyethyl) ethylene diamine ) and 4,4'-diphenylmethane diisocyanate to intercalate the organic modified montmorillonite clay. Then, it is further reacted with the polyurethane prepolymer, which is polymerized from the polytetramethylene glycol and MDI, to proceed the intercalative polymerization to form a polyurethane/clay nanocomposite polymer. From the X-ray scanning analysis it was found that the intercalation was successfully achieved. The distance of interlayer spacing was manifestly enlarged. The mechanical properties were significant1y improved as the content of organo-clay was increased. For the dyeing properties, the dye-uptake was lowered down as the amount of organoclay increased, but the dye-fastness increased to grade of 4-5. |
