WebMay 20, 2024 · In DSC (upper row) only a single melting peak at T m f (final melting) is observed for both polymers for varying heating rates. A major difference between PCL and PEO is the shift of the melting peak T m f with increasing heating rate. For PCL T m f shifts to lower temperatures, while for PEO T m f increases with heating rate. WebJun 19, 2024 · The DSC results showed that thermal parameters (ΔH m,PCL and X c,PCL) of 50PCL-PLGA and 75PCL-PLGA are slightly lower to those for neat PCL sample, and the rapid decrease of those parameters was observed only for …
