利用生物質材料製作成高分子的技術,因具有可降低石油消耗與減少環境碳足跡的環保意義,近年來成為國際上熱門的研究主題。本實驗利用生質材料癸二酸進行聚酯聚合反應,並在過程中添加微量的均苯三酸與己二胺,合成改質型的生質系聚酯,並針對產物進行拉伸、FT-IR、DSC、DMA等物理性質的檢測。這種改質後的生質聚酯具有低溫熱塑的特性,最適操作溫度為65℃,且塑形後的硬化時間僅約2分鐘;此改質生質高分子在室溫下延伸性達103.1%,45℃環境下延伸性更超過350%。根據Creep測試的結果,證實隨著二胺化合物比例的增加,此生質聚酯的彈性也會提升。利用單軸延伸技術可將此高分子加工製作成低溫熱塑薄膜。此高分子未來不論在醫療輔具或紡織品塗佈加工上,皆存在高度應用潛力。
Use of biomass materials produced polymer technology in recent years become a hot research topic in the international, because of to reduce oil consumption and decreased environmental carbon footprint environmental significance. Herein, we synthesized elastomeric polyesters by reacting sebacic acid, ethylene glycol, trimesic acid with various weight percentages of diaminohexane to form a network polyester. Detection the stretching, FT-IR, DSC, DMA, and other physical properties of the modified product. This modified polymer at room temperature extending up to 103.1%, and extending more than 350% in the 45 ° C environment. Creep test results confirmed that with the increase in the proportion of the diamine compound, the modified polyester elastic will be enhanced. The polymer can be processed into a low-temperature thermoplastic films using uniaxial extension. This polymer are highly potential applications in the future, regardless of medical aids or textile coating process.
