DSC results summarizing: (a) The percent crystallinity ($\chi$) as determined through DSC for (solid lines) the PHBV phase of the blend and (dashed lines) the PLA phase of the blend. The impact of the vol.% of the polymer within the blend is more significant in determining crystallinity than the wt.% of CB; (b) the shift in crystallization temperature, $T_c$, with increasing CB for the PHBV phase of the blend (solid lines) and the shift in cold crystallization temperature, $T_{cc}$, for the PLA phase of the blend (dashed lines). For the PLA phase, $T_{cc}$ decreases with increasing wt.% of CB.
