    • 本研究以酯化反應的方式，將數目平均分子量(Mn)為750、2000及5000之聚乙二醇甲醚 (methoxypolyethylene glycol, MPEG)分別與端羧基聚丁二烯橡膠(carboxyl-terminated polybutadiene, CTPB)改質成三種兩親三嵌段共聚物—(amphiphilic triblock copolymer) methoxypolyethylene glycol-b-polybutadiene-b-methoxypolyethylene glycol (MBMs)，並將三種MBMs作為雙酚A二縮水甘油醚(diglycidyl ether bisphenol A, DGEBA) 與4-4'-二胺基二苯甲烷(4,4′-methylene dianiline, MDA)硬化之環氧樹脂DM的奈米區域增韌劑(nano domain toughener)；藉由改變三種MBMs的重量比，在MBMs與DGEBA/MDA混合液的重量比為5:95的比例下，製備出具有不同微觀形態之球狀微胞(spherical micelles)和囊胞(vesilces)均勻分散在DGEBA/MDA基材(matrix)中的環氧樹脂奈米複材─DM-(MBMs)，並以穿透式電子顯微鏡(TEM)觀察其微觀形態(morphology)。實驗結果發現，DM-(MBMs) 可在不影響其模數(modulus)與熱安定性(thermal stability)的情況下，大幅提升其拉伸(tensile)及破壞(fracture)韌性(toughness)；以SEM觀察DM-(MBMs)經斷裂破壞後之表面形態，並進一步探討其破壞機制(fracture mechanism)。

    Three kinds of amphiphilic triblock copolymers—methoxypoly- ethyleneglycol-b-polybutadiene-b-methoxypolyethylene glycol (MBMs) were synthesized via the esterification of methoxypolyethylene glycol (MPEG) of different Mn (750, 2000, and 5000) with the carboxyl-terminated polybutadiene (CTPB). The MBMs were used as nanodomain-toughener and were mixed, at 5wt%, with diglycidyl ether bisphenol A (DGEBA) /4,4′-methylene dianiline (MDA) solution and heat-cured to afford the nanocomposites—DM-(MBMs). By tuning-up weight ratios of MBMs:MBMs of different Mn, the MBMs self-assembled into nanostructured spherical micelles and vesicles and well-dispersed in the DGEBA/MDA matrix. The morphology of the DM-(MBMs) was investigated by transmission electron microscopy (TEM). It was found that the tensile and fracture toughness of the DM-(MBMs) can be improved significantly without reducing their modulus and thermal stability. The fracture surface of the nanocomposites was investigated by scanning electron microscope (SEM) and the fracture mechanism of the nanocomposites was deduced.
