| Abstract: | 本研究於合成聚醯胺6時，分別引入碳酸乙烯酯(Ethylene carbonate, EC)、聚碳酸酯多元醇(Polycarbonate Diols, PCDL)進行共聚合，使聚醯胺6中含有二氧化碳形成綠色高分子材料，且具有環保性。合成產物經由FT-IR、XRD、TGA、DSC、DMA、接觸角、吸水性測試，鑑定其結構與穩定性。
研究發現N-C=O的伸縮振盪吸收峰已表明EC的加入，而C-H基團的伸縮振動已表明PCDL的加入，進而證實聚醯胺6與EC、PCDL有合成成功；EC、PCDL耐熱程度較差，會使裂解點降低及外觀顏色偏黃。
透過XRD證實高EC比例時，促使結構呈現無定型態，而高PCDL比例時結晶無明顯改變。由DSC證實加入EC、PCDL皆降低了結晶度，且隨著添加物的比例增加導致熔點下降，而熱焓會因添加的比例有上升有下降的趨勢；由DMA證實加入EC、PCDL皆降低了Tg點；添加了EC隨著比例的增加導致接觸角角度下降、吸水率上升，PCDL隨著比例的增加有助於增加接觸角角度、降低吸水率。
This study involves the copolymerization of caprolactam with ethylene carbonate (EC) and polycarbonate diols (PCDL) to produce green polymer materials containing carbon dioxide, demonstrating environmental friendliness. The synthesized products were characterized using FT-IR, XRD, TGA, DSC, DMA, contact angle, and water absorption tests to identify their structure and stability. The study found that the stretching oscillation absorption peak of N-C=O has indicated the addition of EC, and the stretching vibration of the C-H group has indicated the addition of PCDL, which further confirmed that polyamide 6 has been successfully synthesized with EC and PCDL; EC and PCDL are more heat-resistant If it is poor, the cracking point will be lowered and the appearance will be yellowish. XRD analysis confirms that a high EC ratio induces an amorphous structure, while a high PCDL ratio has no significant effect on crystallization. DSC analysis demonstrates that the addition of EC and PCDL both decreases crystallinity and lowers the melting point, with varying trends in enthalpy depending on the ratio of additives. DMA analysis confirms that the addition of EC and PCDL both lowers the Tg point. Increasing EC content decreases contact angle and increases water absorption, while increasing PCDL content increases contact angle and reduces water absorption. |
