Thermal and mechanical properties of poly(lactic acid)/poly(butylene adipate-<i>co</i>-terephthalate)/calcium carbonate composite with single continuous morphology

Abstract Poly(lactic acid)/poly(butylene adipate- co -terephthalate) with a content ratio of 90/10, and its calcium carbonate (CaCO 3 ) composites nano- micro-sized particles were prepared by melt mixing. The dependence thermal mechanical properties the on particle size addition CaCO filler was investigated. composite containing five parts (abbreviated as 90 L 10 B 5m C, similarly hereinafter) exhibited α α′ crystallines cooling without fillers. 11m C 11n5m only crystalline, others no discernible crystalline. Jeziorny method showed that crystallization mode poly(lactic acid) chains in different close, Mo crystal growth from others. Changes attributed to overall connection strength which dependent filler. From perspective industrialization, 5n11m preferred.
