WebDSC is a useful tool for studying this phenomenon known as “physical aging”. 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 ). Webheating curve of water. Conic Sections: Parabola and Focus. example
Webmeasurement of heat flow. In the 1960s, Mike O’Neill of PerkinElmer developed the first double-furnace, or power controlled DSC in order to measure heat flow, the movement of heat in and out of a sample, directly. This instrument uses a feedback loop to maintain the sample at a set temperature while measuring the power needed to do this against a WebEnergy and heating Energy transfer.
