对于热固性系统的等温处理和玻璃化的模量评估
|
| Conventional differential scanning calorimetry (DSC) is a technique which has been extensively used to characterize the curing of thermosetting materials based on shifts in the glass transition temperature (Tg), as well as the heat flow and kinetics associated with the curing exotherm. Modulated DSCTM is a new thermal analysis technique which provides the same information as conventional DSC, but in addition provides the unique ability to measure heat capacity continuously even during the exothermic curing process. This new information aids in the generation of temperature-time transformation cure diagrams. Furthermore, for the organic systems studied here, a heat capacity mobility factor can be calculated which agrees well with the widely used diffusion factor, where the latter is defined as the ratio of the observed rate of reaction to the rate of reaction in the absence of diffusion control (i.e., the reaction rate predicted by kinetic modeling). |
