Enhancing compatibility of polylactic acid and lignin through acetylation for improving controlled release of pesticide

Abstract

Improving the compatibility between polylactic acid (PLA) and lignin is crucial for developing innovative PLA-based controlled release systems for pesticides. This study addresses the challenge of enhancing the compatibility of alkali lignin (AL) with PLA by acetylated lignin (ACL). The main aim is to synthesize and evaluate pesticide-loaded microspheres for controlled release performance using fluazinam (FZ) as the model pesticide.
