WebThe DSC thermogram of the HA-g-PCL copolymer revealed two endothermic peaks related to PCL and HA (Fig. 4). Their thermograms revealed a single sharp peak at 55–70 °C and a broad peak at 70–160 °C for PCL (blue line) and HA (red line), respectively. The results above confirmed the formation of HA-g-PCL copolymer. WebApr 5, 2016 · Abstract The crystallization behavior of poly (e-caprolactone)/poly (ethylene glycol) (PCL/PEG) blend was investigated by differential scanning calorimetry (DSC) and polarized microscopy (POM). Individual phase transition peaks in the DSC curves for both PEG and PCL in all the polymer blends with different PCL contents were observed. matthias schindler facebook
