雙軸延伸聚酰胺12薄膜研究

Properties of Bi-axially Oriented Polyamide 12 Film

摘要


本研究利用雙螺桿押出機押出聚酰胺12薄膜,並進行不同倍率雙軸延伸,研究薄膜熱性質與結晶取向關係。首先使用示差掃描量熱儀進行熱性質分析,並探討聚酰胺12結晶動力學。再來分析雙軸延伸聚酰胺薄膜之應力變化以及薄膜性質,包括光學特性、微結構、水蒸氣及氧氣穿透率。

聚酰胺12 雙軸延伸 結晶

並列摘要


In this study, polyamide 12 film was casted by twin screw extruder and followed by bi-axially stretching with various ratios. In the first part, the thermal properties and crystallization kinetics were analyzed by measuring the enthalpy in the adiabatic or isothermal process by using differential scanning calorimetry (DSC). Furthermore, the properties of BOPA 12 film were analyzed including stress, optical properties, micro structure, water vapor transmission rate (WVTR) and oxygen transmission rate (OTR).
