Figure presents the DSC cooling thermograms. The exothermic effect visible on them is related to the process of crystallisation of the polymer from the melt. A significant difference in the crystallisation parameters compared to the other materials can be see especially for the coPBS_20%nHAp sample. It is worth noting that the apatite particles introduced into the PBS-DLS copolymer did not show any clear nucleation effect on the crystallisation phenomenon.
