摘要
生物降解聚合物氧气/水蒸气阻隔性能较差,极大地限制了其在包装领域中的应用。为此,学者们研究了链结构、熔融共混、纳米填充、结晶度、多层复合和表面处理技术等因素对生物降解聚合物阻隔性能的影响。本文主要从化学改性、物理改性和制备技术等方面对生物降解聚合物阻隔性能的最新研究成果进行介绍,以期为进一步深入研究提供参考。
The poor oxygen/water vapor barrier properties of biodegradable polymers greatly limit their applications in packaging.For this reason,scholars have investigated the effects of chain structure,melt blending,nanofilling,crystallinity,multilayer compounding and surface treatment technology on the barrier properties of biodegradable polymers.In this paper,the latest research results on the barrier properties of biodegradable polymers are introduced mainly from the aspects of chemical modification,physical modification and preparation technology,in order to provide a reference for further in-depth research.
