摘要
随着"禁塑令"的推出,可降解材料逐渐走入人们的视野,聚乳酸(PLA)作为一种新型聚酯类可降解材料其应用方面越来越广泛。通过改性可以改善PLA脆性大、结晶速度慢、熔体强度低以及热稳定性差等缺点,但共聚、共混等改性手段也使得改性后PLA复合性透明性有所不足。本文综述了近年来透明聚乳酸复合材料的研究进展,主要介绍了结晶调控、纤维素改性、丙烯酸酯类以及其它有机物改性这四种方法对聚乳酸复合材料透明性的影响,并展望了透明PLA的发展前景。
With the forbidden of the nondegradable plastics, degradable materials gradually walk into people′s vision.Poly(lactic acid)(PLA) is a new type of degradable materials belongs to polyester, its application is more and more extensive in many areas. The disadvantages of PLA, such as high brittleness, slow crystallization speed, low melt strength and poor thermal stability, can be improved by modification. However, copolymerization, blending and other modification methods also lead to the lack of composite transparency of PLA after modification. This paper reviews the research progress of transparent PLA composites in recent years. The effects of crystallization regulation, cellulose modification, acrylate modification and other organics methods on the transparency of PLA composite are introduced, and the development prospect of transparent PLA is prospected.
