Poly(butylene adipate- co -terephthalate) with synergistically enhanced mechanical, moisture/oxygen barrier, and degradation performance via embedding immobilized enzyme

Key Points

• This work aims to improve the service performance and biodegradability of poly(butylene adipate-co-terephthalate) (PBAT) using immobilized enzymes.
• Introduced a high-crystallinity PBAT matrix with MOF-immobilized enzymes.
• Evaluated mechanical and barrier properties of the modified PBAT.
• Analyzed biodegradability through controlled degradation tests.
• Significant enhancement in mechanical strength observed with enzyme embedding.
• Improved moisture and oxygen barrier properties achieved.
• Enhanced biodegradability demonstrated compared to standard PBAT.
