Hybrid PLA /Thermoplastic Starch Biocomposites Reinforced With Spent Coffee Grounds: Effect of Maleic Anhydride on Interfacial Compatibility, Mechanical Performance, and Biodegradability
This study developed hybrid poly(lactic acid) (PLA)/thermoplastic starch (TPS) biocomposites reinforced with spent coffee grounds (AK, 0–30 wt%) and compatibilized with maleic anhydride (MA, 5 wt%). The composites were characterized using Fourier‐transform infrared spectroscopy (FTIR), scanning electron microscopy (S...
