Abstract

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：
