摘要: | 現在應用在醫療方面的生醫材料種類是越來越多,其中近年來以高透濕性材料為特色的應用有著很大的發展潛力,因此也引起許多國內外學者投入相關研究。
而本論文研究主要分成兩個部分: 第一個部分研究方向為提高聚氨酯的透濕能力與其機械強度,期望能在生醫材料方面有更廣泛用途,利用不同重量比的聚二元醇,聚乙二醇(Poly(ethylene glycol))與聚丙二醇(poly(propylene glycol))和1,6-己二異氰酸酯(Hexamethylene diisocyanate)進行聚氨酯合成反應後,再塗佈成膜對其進行熱性質、拉伸、水氣穿透、生物相容性等性質分析。 第二部分亦是第一部分的延伸,由直鏈型改為星狀型聚氨酯,研究方向為合成星狀聚氨酯水凝膠(Polyurethane hydrogel),利用聚丙三醇(Poly(propylene glycol) triol)和二異氰酸異佛爾酮(Isophorone diisocyanate, IPDI),調整不同比例的聚二元醇,聚乙二醇(Poly(ethylene glycol))與聚丙二醇(poly(propylene glycol))來合成星狀的聚氨酯水凝膠,並對其熱性質、水氣透過率、黏著性等進行分析探討。 In my study, it was mainly composed of two major parts. The polymer materials were designed to be with high water vapor transmission rate and well mechanical properties. In the first part, both PEG(poly(ethylene glycol)) and PPG(poly(propylene glycol)) acted as the soft segment were introduced into the procedure of synthesizing polyurethane. We could find the influences of various molar ratio of PEG and PPG on their thermal property, mechanical property, water vapor transmission rate, biocompatibility, and so on. In the second part of the study, it was followed by the first part. By using the PPG triol (Poly(propylene glycol) triol) and changing the molar ratio of polydiols, different star-shaped polyurethane hydrogel were produced. To see the performance of polyurethane hydrogel, thermal property, water vaper transmission rate, adhesion and so forth were analysized. |
