Pcl phase separation
SpletPhase inversion in the separation process results in epoxy as the matrix when the PCL content of the blend is 12 wt %. The macrophase separation process of the PCL 15 wt % blend is similar to the mechanism proposed by Yamanaka and Inoue.13They reported that phase separation takes place via SD induced by the increase in the epoxy molecular weight. SpletPhase separation mechanism in PCL-dioxane with a freezing point of 11.8°C. In short, PCL/dioxane so-lutions at three different concentrations, 0.05, 0.1, and 0.15 g/mL, were …
