Study Of Thermal Stability Of Some Magnetorheological Elastomers

The paper aims to obtain and study two types of magnetorheological materials based on silicone rubber obtained by adding different magnetic materials as well as checking their thermal stability in the presence and in the absence of a magnetic field. The influence of magnetic field on the thermal stability is studied by thermoanalytical techniques: TG/DTG/HF and spectroscopic techniques FTIR-UATR. Thermal degradation of materials is also analyzed using the non-isothermal kinetic methods proposed by Friedman, Flynn-Wall-Ozawa, Kissinger-Akahira-Sunose and also by modified nonparametric kinetic (NPK) methods.
