説明
DSC rewarming traces of cross-linked dextran gels of a certain density of cross-link were known to indicate an endothermic trend at low temperatures below 0℃, followed by an exotherm due to ice crystallization prior to a large endotherm due to ice melting at around 0℃. To elucidate the origin of the endothermic trend observed with cross-linked dextran gels, oscillation DSC as well as X-ray diffraction-DSC simultaneous measurements were carried out. By the oscillation DSC measurement, the endothermic trend during rewarming did not change independent of the frequency and amplitude of the temperature oscillation used in this study. The result obtained indicates that the trend is not of a kinetic origin due to enthalpy relaxation nor is the change in heat capacity on the glass transition. However, decrease in the degree of crystallinity of ice was hardly observed by the X-ray diffraction measurement during the endothermic trend in the DSC scan although the exotherm following the endothermic trend was confirmed to be due to ice crystallization by the X-ray diffraction measurement.
