Abstract
A Differential Scanning calorimetry (DSC) thermal analysis method for the action of an applied electric field includes: step 1, in an experiment module of a differential scanning calorimeter, placing a microelectrode crucible and a reference crucible on corresponding sensors, connecting electrode wires of the microelectrode crucible with a signal generator, setting signal parameters to be output, placing a tested sample in a gap between electrodes, closing a microelectrode crucible lid, and closing the experiment module; step 2, at a temperature-varying stage, measuring a DSC curve of the tested sample under the action of an electric field, and at a reheating stage, measuring a DSC curve of the tested sample with no electric field; and step 3, analyzing the DSC curves in combination with the related theories of dielectrics and thermodynamics, and calculating an electric field intensity of the tested sample and a phase transformation rate of the tested sample.
