Abstract:

With awareness and highlights of environmental protection challenges, it is the trend for some non-biodegradable plastic to be gradually replaced by biodegradable ones. At present, polymer named as polybutylene adipate-co-terephthalate (PBAT), one of the most commercially promising biodegradable plastic with super ductility and flexibility compared favourably with low-density polyethylene, is considered to be one of the most attractive sustainable candidates for contemporary green material manufacturer. However, PBAT faces limitation of application cases, arising from its deficiencies in mechanical properties, thermal properties, barrier properties and production cost, etc.. This paper aimed to systematically review the development on preparation methods of PBAT-based composites in recent years and the work done by domestic and international researchers for improvement of the mechanical and barrier properties of PBAT, as well as the degradation principles and environmental risks associated with the PBAT degradation. Innovative research relevant to PBAT-based composites should be emphasized and further carried forward on topics such as excellent degradability, bacterial inhibition, durability and cost reduction.

Key words: degradable plastics, PBAT, blending modification, degradation

摘要:

随着人们环保意识的提高,可生物降解塑料逐步取代部分不可降解塑料,将成为一个趋势。目前,聚己二酸丁二醇酯-共对苯二甲酸酯(PBAT),作为最具商业潜力的可生物降解塑料,具有与低密度聚乙烯相当的延展性和柔韧性,被普遍认为是当代绿色材料制造中最有前途和最受欢迎的可持续材料之一。但PBAT在力学性能、热性能、阻隔性能及生产成本等方面存在不足,其应用范围受到限制。本文旨在系统性地简述近年来PBAT基复合材料的制备方法、回顾国内外研究人员在PBAT力学性能和阻隔性能等提升方面所做的工作、并详细介绍和讨论PBAT的降解原理和降解所带来的环境风险。开发低成本综合性能优异,兼顾良好降解性、抑菌性和耐久性能的PBAT基复合材料,应当予以重视和进一步研究。
