摘要
介绍了国内外高功能性双向拉伸聚乳酸(BOPLA)薄膜材料成型技术的研究现状,重点综述了基础型、功能型两大类可生物降解BOPLA薄膜的研究进展,包括通过优化基体配方、熔融共挤、拉伸温度、拉伸倍率、拉伸速度及热定型温度等双向拉伸成型技术和基于表层可金属化技术的方式制备可生物降解BOPLA薄膜。最后,对可生物降解BOPLA薄膜的研究趋势进行了展望。
This article reviewed the recent research and manufacturing progresses of biodegradable grade biaxially oriented poly(lactic acid)(BOPLA)film,and intensively introduced two class biodegradable grade BOPLA films processed by basic and functional types.Moreover,the biaxially oriented processing technology in the improvement of resin matrix for⁃mulation,stretching temperature,stretching ratio,stretching rate and heat setting temperature as well as the introduction of method based on metallization technology of surface layer for the preparation of biodegradable grade BOPLA film were also introduced.Finally,development trend of biodegradable grade BOPLA film was prospected.
