摘要

本研究中探討聚己內酯(PLC)或聚乙二醇（PEG）與塑化澱粉(TPS)之掺合物，加工後之熱性質變化。由示差掃描量熱儀(Differential Scanning Calorimetry，DSC)觀察掺合物之熱性質變化得知，聚乙二醇(PEG)與塑化澱粉(TPS)之掺合物於55 ℃有熔融峰，聚己內酯(PLC)與塑化澱粉(TPS)之掺合物於64 ℃有熔融峰。由熔融指數測試(Melt Flow Index ，MFI)測試得知隨著聚己內酯(PLC)的比例增加，掺合物之MFI值由0.33 g/10min提升至42.57 g/10min，表現出良好的熱熔融流動性。拉力試驗機(Universal Materials Testing Machine)測試中，隨聚己內酯(PLC)的比例增加，伸長率從0.592 %上升到200.599 %，而楊氏模數由464.444 MPa下降到4.13 MPa。可大幅增加生物可分解塑膠材料的可製造性。

This research investigates the changes of polymer blends of Preparedpolycaprolactone (PLC) or Polyethylene glycol (PEG) and thermoplastic stach(TPS) in the thermal properties after the processing.
By the Differential Scanning Calorimetry(DSC) observation Polymer blends thermal property change, we draw to the conclusion that Polyethylene glycol (PEG) and blending of the plasticized starch (TPS) has the melting peak at 55 ℃. The blends of Polycaprolactone (PLC) and thermoplastic starch (TPS) of have melting peaks at 64 ℃. Through the MFI test, we presume that with the increasing ratio of polycaprolactone (PLC), MFI values of polymer blends raised from 0.33 g/10min to 42.57 g/10min and showed good mobility of hot melt. Universal Materials Testing Machine, polycaprolactone (PLC) to increase the percentage elongation increased from 0.592% to 200.599%, while the Young's modulus decreased by a 464.444 MPa to 4.13 MPa. Substantial increase in biodegradable plastic materials for manufacturing.
