3.1. DSC analysis
The melt-crystallization DSC curves of pure PBS and
PBS/nano-CaCO3 composites at a cooling rate of 10 C/min
are shown in Fig. 1(a). Table 1 shows the crystallization
onset temperature (To), crystallization temperature (Tc),
crystallization end temperature (Te), melting temperature
(Tm) and crystallinity (Xc) of pure PBS and PBS/nano-CaCO3
composites. The crystallinity (Xc) in all samples was
calculated as follows:
