摘　　要：聚乳酸作为一种可降解的高分子材料,广泛应用于生物医疗、合成纤维、食品包装等领域,但是其较差的阻隔性能,尤其是对水蒸气阻隔性能,限制了其在包装及医学等领域的应用。通过与纳米材料共混改性可明显地提高聚乳酸的阻隔性能。本文分析了聚合物纳米复合材料的阻隔机理,论述了近年来聚乳酸/蒙脱土复合材料阻隔性能方面的研究,并对今后的研究方向进行了展望。As a degradable polymer material,polylactic acid is widely used in biomedical,synthetic fiber,food packaging and other fields.However,its poor barrier property,especially its moisture barrier property,restricts its application in packaging and medical fields.The barrier property of polylactic acid can be obviously improved by blending with nanomaterials.In this paper,the barrier mechanism of polymer nanocomposites is analyzed,and the barrier properties of polylactic acid/Montmorillonite Composites in recent years are discussed,and the future research directions are prospected.
