PBAT/PLA复合材料的制备和性能研究

Preparation and Properties of PBAT/PLA Composites

为了减少传统塑料废弃物在环境中的积累,生物可降解材料备受关注。在众多可降解材料中,聚己二酸丁二醇酯(PBAT)具有完全生物降解性及优异的力学性能,被认为是聚乙烯等不可降解材料的理想替代品。但PBAT存在加工性差、粘度高等一些缺陷,将聚乳酸(PLA)加入到PBAT中可改善其缺陷。本论文综述了五种最常见的PBAT/PLA复合材料的制备方法,并介绍了不同的改性方式来提高BAT/PLA复合材料的性能,并展望了PBAT/PLA复合材料的发展前景。

In order to reduce the accumulation of traditional plastic waste in the environment,biodegradable materials have attracted much attention.Polybutanediol adipate(PBAT)has complete biodegradability and excellent mechanical properties among many degradable materials,which is considered as an ideal substitute for polyethylene and other non-degradable materials.However,PBAT has some defects such as poor processability and high viscosity.Adding polylactic acid(PLA)into PBAT can improve its defects.Five preparation methods of the most common PBAT/PLA composites were reviewed,and different modification methods were introduced to improve the performance of BAT/PLA composites,and the development prospect of PBAT/PLA composites was prospected.
