Temperature-Dependent Mechanical Behaviour of Polylactic Acid Plasticised with a Bio-Based Chitin–Lecithin System
Polylactic acid (PLA) is a bio-based thermoplastic whose inherent brittleness limits mechanically demanding applications. This study investigates how a bio-based chitin–lecithin plasticiser system affects the mechanical behaviour of injection-moulded PLA as a function of additive composition, testing temperature, and a...
