摘要: This article deals with the nonisothermal degradation kinetics of insulating and conducting epoxy/Zn composites. A comparison thermal data obtained from composites revealed that addition zinc content in epoxy significantly increases its rate. However, activates until melting point (419.5°C) then it starts stabilizing matrix due to higher specific heat molten state. Kinetics phenomena fairly explains this behavior terms general kinetic equations for It is notice both values effective activation energy reaction model (Sestâk Berggren/SB-m, n) insulator/conductor composite pair have been found almost same emphasizing upon negligible polymer–metal interactions cases. These mechanistic clues derived comparative study good agreement results through morphological analysis samples by scanning electron microscopy X-ray diffraction techniques. POLYM.
