Unformatted text preview: (even lower than that of the pure elastomer) and the highest activation energy (higher than that of the pure elastomer). Further investigation is required to find the reason. FS-clay and S-clay caused remarkable decrease in the thermal stability of the elastomer. This was due to the ammonium salt surfactant attached to the clays, which decomposed at elevated temperature and the decomposition products catalyzed thermal decomposition of the elastomer. All the tested nanofillers were found to increase the mechanical properties, glass transition temperature, and storage modulus of the elastomer. The degree of improvement depended on their interactions with the elastomer matrix and their effects on elastomer vulcanization....
