Abstract:

This paper reviewed the characteristics of the current industrial production technology and the current industrialization status of PBAT in China and abroad. The remaining gap between PBAT and traditional plastics in terms of performance and cost was pointed out through comparison. In addition, this paper systematically introduced the preparation of degradable materials (PLA, polyvinyl alcohol, polypropylene carbonate and polybutylene succinate), nanomaterials (cellulose nanocrystals, modified cellulose nanocrystals, seafoam and montmorillonite) and natural polymer materials (starch, acetylated green bamboo fibers and industrial lignin) by three different methods of melt mixing, solvent casting and in situ polymerization. The research progress of modified PBAT composites was discussed, and the degradation principles and degradation properties of PBAT composites were discussed. Finally, the future research of PBAT was prospected, and it was pointed out that the future research direction of PBAT production technology should be developed in the direction of high comprehensive performance, low cost and green.

Key words: degradable plastics, PBAT, modification, degradation

摘要:

阐述了目前国内外聚(己二酸丁二醇酯-对苯二甲酸丁二醇酯)(PBAT)工业生产技术特点和产业化现状,通过对比指出了PBAT与传统塑料在性能、成本等方面尚存差距。系统介绍了现阶段国内外研究人员通过熔体混合、溶剂浇铸和原位聚合三种不同方法,制备可降解材料(聚乳酸、聚乙烯醇、聚碳酸亚丙酯和聚丁二酸丁二醇酯)、纳米材料(纤维素纳米晶体、改性纤维素纳米晶体、海泡石和蒙脱土)以及天然高分子材料(淀粉、乙酰化绿竹纤维和工业木质素)改性PBAT复合材料的研究进展,并对PBAT复合材料的降解原理和降解性能进行了讨论。最后对PBAT未来的研究进行了展望,指出PBAT生产技术的未来研究方向应该向综合性能高、低成本和绿色方向发展。
