Effects of structural recovery in modulated DSC

Research output: Contribution to conferencePaperpeer-review

Abstract

It is well known that structural recovery in polymeric glass formers leads to highly nonlinear events, such as enthalpy overshoot, in non-isothermal experiments. Or common model for describing these events is the Tool-Narayanaswamy (TN) equation. Here we apply the TN equation to analyze a typical modulated DSC (MDSC) trace and examine the influence of the material non-linearities on the dynamic heat flow. We also study their impact on the reversing and non-reversing heat flows and compare the values of Cp obtained considering the TN model with those obtained from the MDSC output when the material non-linearities are ignored.
