WebSep 5, 2010 · First of all, the DSC of HYA/water systems was carried out for different water concentrations; examples of DSC records for low concentrations are given in Fig. 2. Fig. 2 shows the heating run, i.e. ice melting records for HYA (740 kDa) with various concentrations of water; the dotted line represents the hypothetical straight baseline … WebFor DSC/TGA, a TA Instruments (New Castle, DE) Q600 SDT was used for sample measurements. Samples were stored dry ice on prior to transfer to the platinum sample pans via a gas-tight microliter (µL) syringe. After transfer of 25 µL of sample to the pan the pan, was immediately covered with a 120 (to reduce rapid -mesh screen

The initial DSC heating scan of physically aged polymers commonly reveals an endothermic peak near the trailing edge of the Tg step-change. This peak is referred to as the “enthalpy of relaxation” or “enthalpic recovery” (ΔH R ).
