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