热塑性聚乙烯醇对聚乳酸结构与性能的影响
Effect of Thermoplastic Poly(vinyl alcohol) on Structure and Properties of Poly (lactic acid)
摘要
Abstract
Poly(lactic acid)(PLA)/poly (vinyl alcohol)(PVA) blends were prepared by a melt blending method,and their structure and properties were investigated by tensile and impact tests,scanning electron microscopy and scanning electron microscopy.The results indicated that the blends achieved an optimum comprehensive properties when 2 wt ％ of PVA as an impact modifier was introduced.The impact strength,tensile strength,elongation at break,glass transition temperature and melting temperature of the blends reached 15.6 kJ/m2,52.7 MPa,4.2 ％,62.8 ℃ and 167.9 ℃,respectively.关键词
