Crosslinking natural rubber(NR)and styrene butadiene rubber(SBR)composites with carbon black(CB)have been utilized in the tire tread industry.A sulfur-based lightly crosslinker can potentially enhance the self-healing capabilities of rubber.Moreover,the rubber composites were studied for non-covalent interactions between the benzene rings of SBR and CB.In this research,rubber samples were prepared,and their structure was investigated using Fourier transform infrared(FTIR),and Raman spectroscopy.The red shift in Raman spectroscopy confirmed non-covalent interaction or hydrophobic interaction between SBR and CB in NR/SBR composites exposed to CB due to environmental change.The dif-ferential scanning calorimetry(DSC)thermograms showed that NR and SBR were incompatible.Additionally,the mechanical properties of these rubber blends were enhanced as the proportion of NR increased.The maximum self-healing performance reached 40％for the formulation con-taining 25 phr NR and 75 phr SBR,which also saved energy with low chain end movements.Therefore,these composites could be utilized as a se-mi-empirical model for studying crosslinked rubber blends,specifically in the rubber tire industry.
