In this research, the effect of a modified carbon black on the morphology and dynamic properties of nano-silica/Natural rubber nanocomposites was studied. The results revealed that the modification process influenced curing properties. The ∆Torque increased to the value of 13.6 dN.m after surface modification. Scanning electron microscopy (SEM) analysis indicated better dispersion of the modified CB in NR nanocomposites. The dynamic-mechanical analysis (DMA) showed that modified CB reduced rolling resistance and improved wet grip potential. Also, utilization of modified CB decreased glass transition from -56 ℃ to -65 ℃. Overall, selecting modification approaches is crucial for achieving optimal results in the performance and application of rubber compounds.
