Polylactic acid (PLA) exhibits remarkable biocompatibility and biodegradability, rendering it a highly promising material for applications in packaging disposable products. However, its inherent brittleness, low melt strength, slow crystallization rate significantly restrict practical uses. Our previous studies have shown that incorporating the ADR chain extender can yield chitosan–polylactic acid–ADR (CS/PLA-ADR) composites with outstanding antibacterial properties, enhanced capability to effectively block water vapor oxygen. elongation at break (less than 10%) limits application scenarios require high ductility. To enhance toughness of CS/PLA-ADR composites, flexible biodegradable polybutylene succinate (PBS) is innovatively introduced. The mechanical properties PBS be compared polyethylene polypropylene, providing strength toughness. mechanism introducing construct good, toughened structure through collaboration toughening agent, achieving balance between CS/PLA-ADR-PBS composites. incorporation anticipated improve ductility This study systematically investigates effects varying content (0–30%) on aiming determine optimal elucidate by which enhances overall performance results indicate when 20%, exhibit properties. research provides theoretical foundation technical support development environmentally friendly sustainable materials, offering significant value broad prospects.
