摘要: Poly(lactic acid) (PLA)/poly(butylene succinate) (PBS) blends were prepared using a carboxylic acid salt as nucleating agent (NA). The effect of NA on the crystallization kinetics PLA and PLA/PBS blend was investigated differential scanning calorimeter, polarized optical microscope wideangle X-ray diffractometer. rate component in is increased effectively by through fast nucleation growth α'-form crystal, which confirmed isothermal behavior PLA/PBA/NA composites. results also show that incorporation induces heterogeneous mechanism component. number crystal nuclei hinders increase average grain size composites but contributes to higher crystallinity both PBS components blends. Finally, mechanical properties dynamic PLA/PBS/NA are improved because crystallinity, superior blend.
