ОСТАННІ ДОСЯГНЕННЯ У СТВОРЕННІ ПЛІВКОУТВОРЮЮЧИХ ЕМУЛЬСІЙ НА ОСНОВІ БІОПОЛІМЕРА PLA

Poly(lactic acid) (PLA), a biodegradable biopolymer, faces challenges in coatings due to film formation and stability issues. To enhance performance, researchers use plasticizers, flexibilizers, and cross-linking agents. Emulsification techniques like solvent evaporation, high-shear mixing, and ultrasonic emulsification aid PLA dispersion, with recent focus on solvent-free methods such as reactive extrusion. Stabilizers like polyvinyl alcohol, casein, and pectin improve emulsion stability. However, issues like phase separation, high energy demands, and residual solvents persist. Research into eco-friendly stabilizers, green processing, and PLA nanocomposites aims to enhance mechanical properties and scalability. PLA emulsions show promise for wood finishes, food packaging, and biomedical coatings, reducing volatile organic compound emissions. Advancements in formulation and processing will be key to unlocking PLA-based coatings’ full potential.
