摘要

本研究探討以原位聚合法製備聚醯胺6/多壁奈米碳管/奈米黏土複合材料。
本研究之實驗將多壁奈米碳管進行改質，並藉由FTIR進行分析。並利用己內醯胺（ε-caprolactam，CPL）聚合成PA6的過程中，添加不同比例的多壁奈米碳管與奈米黏土，經過聚合、純化、乾燥之程序製得PA6/MWCNT/Clay的複合材料試樣。並探討其熱性質、機械性質、功能性質。
ATR-FTIR結果說明添加粉體並未出現與純PA6不同之官能基特徵峰或是造成偏移現象。由SEM觀察複合材料表面型態之分散狀況。TGA分析PA6複合材料之熱裂解溫度及成炭率。紅外線熱影像溫差測試分析發現複合材料之升溫速率、降溫速率與蓄熱能力隨奈米碳管粉體添加量之增加而升高。限氧指數儀進行難燃測試，顯示添加1％奈米碳管1％奈米黏土的材料有較好的阻燃效果。

In this study, preparation and characterizations of composite materials, Polyamide 6/ multi-wall carbon nanotubes/ clay were investigated.
The multi-wall carbon nanotubes were modified then it was analyzed by FTIR. The multi-wall carbon nanotubes and clay with various ratios were added with ε-caprolactam during the process of PA 6.Such PA 6/ multi-wall carbon nanotubes/ clay composites were prepared by purification and vacuum drying procedure. The thermal behaviors, mechanical and functional properties were also investigated.
ATR-FTIR analysis showed neither new group was made nor phenomenon of displacement was happened. The surface analysis was observed by SEM. The decomposition temperature and char yield of the PA6 composites were analyzed by TGA. The infrared thermal imager was used to measure the thermal conductive properties of composites. Through the results of limiting oxygen index,we found that the 1wt.％ multi-wall carbon nanotubes/ 1wt.％ clay composite had the optimal flame retardant property.
