Abstract

The present study describes the effect of thermo, thermo-oxidative, and ozone exposure on the retention of physical property of organoclay nanocomposites. Accelerated thermal aging is carried out at 130°C for 30 h. Accelerated thermo-oxidative aging is carried out at 105°C for 7 days. Samples are exposed to 50 pphm ozone atmosphere for 24 and 48 h. The result indicates that the retention of physical property is better in nanocomposites compared to carbon black-filled compounds under thermal and thermo-oxidative aging. Besides, ozone resistance is also relatively superior for nanocomposites. The superior barrier property of the nanocomposites is attributed to the better retention of the physical property after aging.
