Kinetic analysis of peroxide cured natural rubber/layered silicate nanocomposites using thermogravimetry
Material type:
TextPublication details: Rubber Science 2018Description: 69-76Subject(s): Summary: The thermal stability and kinetics of thermal degradation of natural rubber/layered silicate nanocomposites were studied by thermogravimetric analysis (TGA). The nanoclays selected were cloisite Na+, cloisite 10A, cloisite 15A and cloisite 93A. Gum and commercial clay (English Indian clay) were used as reference materials. Dicumyl peroxide (40;active) was used as the crosslinking agent. The activation energy for the degradation of NR/layered silicate nanocomposites was determined by applying Liu and Fan method. Results showed that the thermal degradation is a first order reaction and organically modified clays exhibited the highest thermal stability.
