| 摘要 | 本論文主要研究以融熔插層法與高分子溶液法製備PHBV/蒙脫土奈米複合材料的製備，並量測與探討其XRD、TGA、DMA、DSC與流變測試。以XRD來觀察蒙脫土之層間距受插層劑與PHBV插層情形，結果顯示其形成插層型奈米複材。本研究並以平板式流變儀來量測其融熔動態性質，以TGA與DMA測定奈米複合材料的熱性質及機械性質，結果發現融熔動態性質其模數隨著clay的比例增加而呈現遞減，而熱裂解溫度可提昇100C，固態機械性質則影響不大，Tg亦無改變。 In the research, nanocomposites based on biodegrable poly(3-hydroxybutyric acid-co-3-hydroxyvaleric acid)(PHBV) and organically modified layered silicates(organoclay) were prepared by melt-intercalation and solution-mixing. Their structures and properties were characterized by X-ray diffraction, thermal analysis, mechanical analysis and rheological measurements. The PHBV/organoclay nanocomposites have been formed with intercalation structure that was assessed by X-ray diffraction. Thermal and mechanical properties of nanocomposites were analyzed by TGA and DMA, and the rheological properties was measured by plate-plate Rheometer. The result indicated that thermal decomposite temperature(Td) can be increased up to 10 degree C which were compared with pure PHBV, and the result of the dynamic storage modulus and the glass transition temperature (Tg) can't make a great difference. The shear storage modulus and loss modulus were decreased with the increasing of the organoclay loading, and that was caused by week interaction between PHBV and organoclay. |
