The effect of modified carbon black on filler dispersion and dynamicproperties of natural rubber nano compounds

In this research, the effect of a modified carbon black on the morphology and dynamic properties ofnano-silica/Natural rubber nanocomposites was studied. The results revealed that the modificationprocess influenced curing properties. The ΔTorque increased to the value of ۱۳.۶ dN.m after surfacemodification. Scanning electron microscopy (SEM) analysis indicated better dispersion of themodified CB in NR nanocomposites. The dynamic-mechanical analysis (DMA) showed thatmodified CB reduced rolling resistance and improved wet grip potential. Also, utilization of modifiedCB decreased glass transition from -۵۶ ℃ to -۶۵ ℃. Overall, selecting modification approaches iscrucial for achieving optimal results in the performance and application of rubber compounds.
