摘要
聚乳酸(polylactic acid,PLA)是一种以植物资源为原料合成的聚酯,可用于包装材料,对环境不产生任何污染。但聚乳酸耐热性差、脆性大限制了在行业中的实际应用,将PLA膜同金属及金属氧化物纳米粒子复合是一种可以有效改善聚乳酸膜性能的方式,本文概括了聚乳酸薄膜制备方法及特点,介绍了Ag、TiO_(2)、ZnO、SiO_(2)纳米粒子和聚乳酸复合膜,主要综述了这些纳米粒子对聚乳酸膜性能的影响及机制,最后对此类复合膜存在问题和未来发展进行展望。
Polylactic acid(PLA)is a kind of polyester synthesized from plant resources,which can be used as packaging materials without any pollution to the environment.However,the poor heat resistance and brittleness of PLA restrict its practical application in the industry.It is an effective way to improve the performance of PLA film by compounding PLA film with metal or metal oxide nanoparticles.This paper summarizes the preparation methods and characteristics of PLA film,introduces Ag,TiO_(2),ZnO,SiO_(2) nanoparticles and PLA composite films,and summarizes the effect of these nanoparticles on the performance of PLA film.The influence and mechanism of these nanoparticles on the properties of polylactide films are also mainly reviewed,finally the problems and future development of this kind of composite films are prospected.
