A Facile Strategy for Compatibilization of PLA/PBS Blends by Incorporating Camellia Seed Powder

Using biodegradable blending materials is one of the most effective ways to address plastic pollution but it hindered by its poor interfacial interaction along with high costs. Herein, an envirionmentally friendly filler, camellia seed powder (CSP)?a byproduct after defatting, reported, which first served as a compatibilizer in polylactic acid (PLA)/polybutylene succinate (PBS) blends without any other aids or complicated pretreatment, effectively toughening PLA/PBS due better interaction. The results show that toughness composites increases CSP content. With addition 30 phr CSP, impact strength and elongation at break increase 44.31% 148.42%, respectively, compared blend CSP. combined effects improved bonding, reduced particle size PBS efficient stress transfer are responsible for enhancement. compatibilization mechanism proposed ?COOH groups PLA react ?NH2 above finding provides facile inexpensive strategy fabrication high-performance materials.
