摘要：
In this work we analyzed the thermogravimetric data on the fiber phase change composites loaded with eicosane or stearic acid. The consistency of the thermogravimetric data can be checked using the Kolmogorov-Johnson-Mehl-Avrami equation with a temperature-dependent rate constant. However, the first derivative analysis shows that the employed equation should be further modified in order to account for the asymmetry of the peaks on the first derivative of thermogravimetric curves.
