本論文合成出不同單體數之乳酸寡聚物及一系列新型具甲基丙烯酸酯之生物相容性光固化單體,透過具有環氧基團之結構可於鹼性環境下,將環氧基團開環並與去離子水和其他具羧酸基團之生物相容性單體進行酯化反應,藉由改變乳酸寡聚物之單體數目以及交聯劑比例,以合成出具不同特性之新型具生物相容性光固化單體,再以核磁共振光譜圖譜(NMR)、凝膠滲透儀(GPC)以及質譜儀(MASS)鑑定其單體數目以及分子結構,接著於此三種新型光固化單體加入TPO光起始劑, 並利用數位式旋轉黏度計、傅立葉轉換紅外線光譜儀(FTIR)、萬能材料試驗機、熱重分析儀(TGA)、示差掃描熱分析儀(DSC)、接觸角量測儀、平均膨潤動力分析法與細胞毒性測試(MTT Assay)分析各新型光固化單體之黏度及光固化後之聚合程度、機械強度、熱穩定、表面親疏水性、平均膨潤度與速率及細胞毒性等性質。
In this research, we synthesized the lactic acid oligomers with different number of monomers and a series of new biocompatible UV-curable materials with special compound have been synthesized. Under basic conditions, the epoxide group of glycidyl methacrylate was opened and reacted with deionized water or other monomers that have carboxylic acid by esterification. By varying the number of monomers of the lactic acid oligomer and the proportion of the crosslinker, we used the nuclear magnetic resonance spectroscopy(NMR), Gel Permeation Chromatography(GPC) and the mass spectroscopy (MASS) to identify the structures of monomers. Then we used TPO as photoinitiator and analyze their properties, such as viscosity, the degree of polymerization, mechanical strength, thermal stability, hydrophilicity or hydrophobicity on the surface, swelling ratio, swelling rate and cytotoxicity by viscometer, FTIR, Universal Testing Machine, TGA, DSC, Contact Angle, swelling test and MTT assay.
