摘要:	本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，並量測與探討其XRD、TGA、DMA、DSC與流變測試。以XRD觀察蒙脫土之層間距受插層劑與PHBV插層之影響，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流變性質，以TGA、DSC與DMA測定奈米複材的熱性質及機械性質，結果發現其融熔態之模數隨著clay比例增加而呈現遞減，而熱裂解溫度可提昇約10℃，固態機械性質則影響不大，Tg亦無改變。 In this research, nanocomposites based on biodegradable poly(3-hydroxybutyric acid-co-3-hydroxyvaleric acid)(PHBV) and organically modified layered silicates(organoclay) were prepared by the melt- intercalation and the solution-mixing methods. 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 were measured by plate-plate rheometer. The result indicated that the thermal decomposite temperature(Td) can be increased up to 10℃ relative to the virgin PHBV, and the dynamic storage modulus and the glass transition temperature(Tg) do not make much difference. The rheological measurements showed that the storage and the loss moduli were decreased with the increasing of the organoclay loading, which can be ascribed to the week interactions between PHBV and the organoclay.
