    • 本研究將PA12與TPU先進行流變行為分析以了解膠粒之最適化加工條件後，將PA12、TPU進行摻合並押出，出來之TPU/PA12摻合物系列再做熱延伸加工以提升物性強度。
    再將PA12、TPU、TPU/PA12摻合物系列進行熱性質探討、機械性質探討、型態觀察。熱性質進行之項目有：TGA、DSC、DMA；機械性質進行之項目有：拉伸試驗及撕裂強度試驗；型態觀察則是使用XRD。再將數據進行分析，以了解PA12與TPU摻合物不同比例的相容性，以及熱性質、機械性質、型態觀察和經過老化處理後的影響。
    最後使用T-Die押出PA12薄膜，以雙軸延伸之延伸溫度與延伸倍率做為變數，對PA12薄膜做延伸，再將延伸後之樣品做抗拉強度的試驗，對於不同的延伸溫度及延伸變量會對PA12薄膜造成不同的應力變化。並觀察雙軸延伸後PA12之結晶性等型態學的探討。

    In this research, we learned the most suitable working condition of chip via Rheological analysis of PA12 and TPU, followed by the blending and extending of TPU and PA12. The product, TPU/PA12, was then intensified by heat stretching processing.
    After the heat stretching processing, we analyzed thermal properties, mechanical properties and morphological properties of TPU, PA12 and TPU/PA12. In this report, thermal properties includes TGA、DSC、DMA, mechanical properties involves tensile test and tear test and morphological properties was analyzed by using XRD. The data was then undergone analyzing to investigate the compatibility of the different proportion of TPU to PA12, thermal properties, mechanical properties, morphological properties as well as the effect of aging.
    Finally, PA12 film was extended by using T-Die with variables of stretching temperature and stretching times of biaxial oriented. To investigate the stress variation of PA12 in different stretching temperature and stretching times, Tensile test was used to test the stress of the product been extended. In addition, the crystallization of PA12 after biaxial orientation was observed, thereby, we can examine the morphology in detail.
