【摘要】 采用X-射线衍射仪对AS/PVA生物降解包装塑料进行了凝聚态结构表征并将醋酸淀粉酯、聚乙烯醇和AS/PVA生物降解包装塑料进行了比较。结果表明醋酸酯淀粉衍射角(2θ)在15.17°、17.94°、23.15°附近的三个极强衍射峰在成型加工后均消失,而在19°附近又出现了一个新的衍射峰,说明结晶度降低,部分晶区转变为非晶区。更多还原

【Abstract】 The aggregation structure of the AS/PVA biodegradation Packaging plastic were characterizated by using of the X-ray diffraction analyzer.The SA,PVA and AS/PVA biodegradation Packaging plastic were compared.The results show that three strongly diffraction peek about 5.17°,17.94°,23.15°have vanished,a new diffraction peek about 19°have appeared.It is show that the crystallinity degree decreases,a part of crystal zone have changed into non-crystal zone.更多还原
