摘要: Natural rubber (NR)-barium ferrite (BaF) composites (RFCs) have been prepared. Structural features of the were characterized by Infrared spectroscopy and scanning electron microscope (SEM). Differential calorimetry (DSC) analysis showed that there is small variation glass transition temperature (≈ –1℃). The activation energy was calculated Kissinger method has values between (53-110 kJ/mol). Thermodynamic parameters such as activated entropy, enthalpy Gibbs free for also. Thermogravimetric TG its derivative DTG one stage thermal decomposition 300℃-400℃ with weight loss (19.47%-52.13%). Increasing barium loading will increase stability natural rubber. kinetic energy, in region analyzed using Coats-Redfern technique.
