Effect of elastomeric nanoparticles as co-reinforcing agent on rubber composites

Elastomeric nanoparticles (ENPs) are rubber nanoparticles that have different effects than carbon black (CB) when added to rubber composites. To further understand the effects of ENPs on rubber composites, the morphologies, viscoelasticity, mechanical properties, and interactions with rubber were carefully studied. The results revealed that ENPs and CB differed in terms of their dispersion states and reinforcing effects on rubber. The addition of ENPs can reduce the free chain ends of rubber composites, which helps reduce the rolling resistance, making it a possible way to develop energy-saving tires. Compared with current techniques for lowering the free chain ends of vulcanisates, it is easier and simpler to add ENPs to rubber composites. The results also show that ENPs and CB had a synergistic effect on rubber reinforcement. The optimal ENP content, considering the vulcanisate characteristics, was approximately 10 phr.

Automated summary

Elastomeric nanoparticles (ENPs) have different effects than carbon black (CB) on rubber composites. The study investigates their morphologies, viscoelasticity, mechanical properties, and interactions with rubber, revealing differences in dispersion states and reinforcing effects. Adding ENPs reduces free chain ends in rubber composites, decreasing rolling resistance and enabling the development of energy-saving tires. Compared to current techniques, adding ENPs to rubber composites provides a simpler and easier way to lower free chain ends. The study also shows a synergistic effect of ENPs and CB on rubber reinforcement, with an optimal ENP content of approximately 10 phr based on vulcanisate characteristics.
