[交流] 玻璃化转变和复苏测量

ABSTRACT
This paper provides a summary of recommendations designed to permit optimization of Modulated DSC results. It also describes two important aspects (frequency dependence and enthalpic recovery) of the important glass transition measurement that can be readily determined from DSC and MDSC experiments.
INTRODUCTION
Measurement of the glass transition and glass transition temperature are probably the most common measurements made with the DSC and MDSC techniques. In a previous paper in this series entitled “Optimization of MDSC Experimental Conditions”, recommendations were provided for selection of experimental conditions (modulation amplitude and period, and heating rate). As discussed therein, selection of experimental conditions can significantly affect measurement sensitivity and resolution. A summary of these effects is given in the following section.
