Principle and Applications of Differential Scanning Calorimetry

Abstract

DSC, Differential Scanning Calorimetry, can detect information of the phase transition of the materials, the heat history, the thermal curing, specific heat capacity, and purity, etc., it is used in various fields such as the polymer, the metal, the ceramic, the medicine, and the food. Especially, information available from DSC is important in not only development but also the optimization of the manufacturing process in a high performance polymer as blended polymer, polymer with filler, multilayer thin film and so on. This paper introduces measuring principles of DSC, a relationship between phase transitions of polymer materials and DSC behavior, and some applications for polyethylene terephthalate (PET) and toner.
