This research aims to understand how PLA composites degrade over time when exposed to different food simulants.
Aged PLA composites containing grape pomace and Ag/Cu nanofillers for six months.
Performed HV, SEM, FTIR, DSC, and EPR analyses to assess material changes.
Evaluated the effects of different food simulants on degradation.
Observed varying degradation pathways based on the composite formulation.
Identified significant changes in mechanical and structural properties of PLA composites after aging.
Described specific degradation mechanisms influenced by the type of food simulant used.
Abstract
PLA composites containing grape pomace and Ag/Cu nanofillers were aged in food simulants for six months. M change , HV, SEM, FTIR, DSC, and EPR analyses reveal formulation-dependent degradation pathways.
