摘要

本研究探討PA 6（Polyamide 6, Nylon 6）在原位聚合方法（In situ polymerization）中加入次微米無機散熱涼爽之礦石粉體（CDS）以製備其PA 6/ CDS散熱涼爽複合材料。利用己內醯胺（ε-Caprolactam, CPL）合成PA 6之過程中，將次微米無機散熱涼爽之礦石粉體（CDS）加入至CPL混和均勻，再經純化、真空乾燥處理後製成PA 6/ CDS複合材料，再以相同之製程改變其次微米無機散熱涼爽之礦石粉體之含量，進而探討散熱涼爽粉體含量對PA 6/ CDS複合材料物理性質、熱性質、機械性質與功能性質之影響。
藉由ATR-FTIR對PA 6/ CDS複合材料做表面特徵官能基分析，發現添加散熱涼爽粉體（CDS）並未出現新的官能基特性峰或是造成偏移現象，代表本研究屬於物理混掺；以EDS對PA 6/ CDS複合材做元素分析，圖譜中出現Ca與Mg的元素特徵峰。經由相對黏度與胺末端基測試，發現隨著散熱涼爽粉體添加量之增加，其相對黏度與分子量會有下降之趨勢；且進一步利用SEM來觀測散熱涼爽粉體在複合材料中之分散狀況。在熱性質分析方面，透過TGA探討其熱裂解溫度及殘餘量間之關係，以了解其加工性質；並由DSC測試，以探討其玻璃轉移溫度(Tg)及熔點(Tm)之變化。並且對PA 6/ CDS複合材料做拉伸與壓縮之機械性質結果分析，隨熱涼爽粉體添加量增加，使複合材料由硬而韌之特性轉為硬而強。最後利用Q-max、迅速導熱係數測定儀及熱電偶式溫差測試系統以測試其功能性質，隨熱涼爽粉體添加量增加，其散熱涼爽之功能性質提升之趨勢。

In this study, the submicron inorganic cooling powders (CDS) were added during the process of PA 6 (Polyamide 6, Nylon 6) in situ polymerization to fabricate composites with coolness effect. It was in the course of synthesizing ε-caprolactam (CPL) to form PA 6, the submicron inorganic cooling powders (CDS) with various amount were added. Such PA 6/ CDS composites were fabricated by the purification and vacuum drying procedure. The effects on the chemical, mechanical and thermal properties of PA 6/ CDS composites with various loading of cooling powders were investigated. The data of ATR-FTIR analysis showed neither new group was made nor phenomenon of displacement was happened. From the EDS results, the featuring peaks of Ca and Mg were noticed. The relative viscosity and molecular weight of PA 6/ CDS composites were obtained from the determination method of relative viscosity and amino end groups. The experiment results showed that the relative viscosity and molecular weight of PA 6/ CDS composites decreased with the increasing quantity of cooling powder. Also, the surface analysis of cooling composites was conducted by SEM. As to obtain the thermal properties of PA 6/ CDS composites, the decomposition temperature of composites and its relationship to the weight loss were examined by TGA. In addition, the variation in glass transition temperature (Tg) and melting temperature (Tm) were analyzed with DSC. Furthermore, the tensile property and compressibility of PA 6/ CDS composites were studied. From the experimental results, it showed that the hard and though characteristics of such composites were turned into hard and strong while increasing the quantity of cooling powder. Finally, the functional properties were analyzed by Q-max, quick thermal conductivity meter and thermocouple temperature testing system. It was observed that the coolness effect increased with increasing the quantity of cooling powder.
