英文摘要:

      The work aims to review the commonly used strategies for blending and modifying biodegradable plastics at home and abroad, and provide ideas and theoretical methods for the industrial development of high- quality biodegradable plastics. Based on the fact that blending modification was a commonly used strategy for polymer material modification, which was widely adopted due to its high efficiency and economic characteristics, this article focused on the biodegradable polymer materials. Poly (lactic acid) (PLA), butylene terephthalate (PBAT), and polybutylene succinate (PBS) were selected as objects to summarize, conclude and analyze the current research status of toughening blending modification. At the same time, the toughening and modification effects, advantages and disadvantages of each were compared. In conclusion, replacing non degradable plastics with biodegradable plastics can greatly alleviate current environmental pollution problems. It has broad application prospects in future plastic films and coating materials.
