Effect of matrix composition on the performance of calcium carbonate filled poly(lactic acid)/poly(butylene adipate-<i>co</i>-terephthalate) composites

Abstract The ratio of poly(lactic acid) (PLA), poly(butylene adipate- co -terephthalate) (PBAT), and calcium carbonate (CaCO 3 ) fillers in PLA/PBAT/CaCO composites was set at 90/10/5, 70/30/5, 30/70/5. effect nano- micro-CaCO on the melting crystallization performance investigated by differential scanning calorimetry. PLA related to PBAT ratio, cooling rate, CaCO particle size composites. Nano-CaCO prevented 90/10/5 70/30/5 but did not prevent Unlike nano-CaCO , regardless ratio. Nano- enhance PLA90 PLA70 some extent, due aggregation dissociation filler polylactic acid. But improved mechanical properties PLA30 several times, good compatibility PBAT. had no significant difference.
