Determination of thermal kinetic parameters of the PVDF + PKR12 composite
 pdf 

ABSTRACT

The change in the heat flux and specific heat capacity of the PVDF + PKR12 composite at the temperature range (-100÷600)°С have been studied. Endothermic peaks were observed in all samples at (158-160)°C, and exothermic peaks were observed at (430-495)°C. From the characteristic points of the thermogram curve, the specific heat of the samples, the change in enthalpy and entropy, and the degree of crystallinity were calculated from the known formulas.

Keywords: differential scanning calorimetry, heat capacity, polymer, piezophase, enthalpy, entropy, ceramics, thermogram.
