Application Note

Study Rigid Amorphous Fraction in Polymer Nano-Composites by StepScan and HyperDSC

Introduction

Heat capacity measurement has been performed in order to detect a possible second Tg on nanocomposites of polymethyl methacrylate (PMMA) with silicon oxide nanoparticles of different shape. StepScan™ DSC was used for determination of precise heat capacity and HyperDSC® to prevent degradation and identify devitrification of the RAF at elevated temperatures.
