Study on the Performances of PLLA/CaSiO3 Composites

In the current work, calcium silicate (CaSiO3) was blended with poly (L-lactic acid) (PLLA) to prepare PLLA/CaSiO3 composites, and crystallization process, melting process thermal decomposition behavior of composites were studied. The promoting effect CaSiO3 on PLLA proved by melt-crystallization, content a crucial factor PLLA. temperature significantly affected PLLA, double peaks degenerated into single peak increasing from 90 °C 130 °C. Additionally, for given sample, different processes in heating after melt-crystallization results rates, appearance cold-crystallization indicated medium nucleation capacity CaSiO3. presence decreased onset this depended competitive relationship poor compatibility high stability.
