“…The composites showed increasing storage modulus and energy dissipation capability, while decreasing loss factor. An et al 21 used water-soluble 2-mercapto-1-methylimidazole to functionalize GO. The modified GO/NR composites showed high tensile strength, abrasion resistance, and heat resistance index, compared with the GO/NR composite.…”

High wear-resistance and fuel-saving tires play an important role in reducing the environmental pollution caused by automobiles. The filler dispersion and interfacial interactions are both crucial for affecting the wear and rolling resistances of rubber composites. In this study, the ionic liquid 1-aminopropyl-3-methylimidazolium chloride (IL–NH2) was specially selected to tune the surface characteristics of graphene oxide (GO), and then the modified GO (IL–NH2–GO) was further introduced to a natural rubber/solution-polymerized styrene–butadiene rubber (NR/SSBR) matrix to investigate the effects of the IL–NH2 dosage on the microstructure and properties of the IL–NH2–GO/NR/SSBR composites. The results showed that the filler dispersion and interface between the fillers and rubber macromolecules were enhanced by introducing an appropriate IL–NH2 content. Owing to the change in the chemical structure of the GO-surface and lubrication effect of the IL–NH2, the filler dispersion was obviously improved, and the friction was reduced between the GO and rubber macromolecules. When the IL–NH2-to-GO mass ratio was 1:1, the 100% modulus and tensile strength of the IL–NH2–GO/NR/SSBR increased by 18.5 and 7.8%, respectively, compared with those of the GO/NR/SSBR composites. Meanwhile, the wear and rolling resistances improved by 8.6% and decreased by 10.4%, respectively. This research indicates that the facile strategy developed for modifying GO with ionic liquids has promising potential for preparing eco-friendly tires exhibiting high wear and low rolling resistances.

Carbon black is a very important reinforcing agent for rubber, which can significantly improve rubber modulus, strength, and abrasion performance. However, there are defects such as large hysteresis loss, dynamic energy loss, and high heat build‐up by using carbon black to reinforce rubber. In this paper, a new silane coupling agent named M1 was prepared and introduced as the coupling agent of carbon black, and M1 modified carbon black was prepared. The Fourier transform infrared spectroscopy, thermogravimetric analysis, and X‐ray photoelectron spectrometer results demonstrated the successful modification and revealed the interaction mechanism between M1 and carbon black. The results showed that strong interfacial bonding can be generated between M1 and carbon black through physical and chemical interactions, thereby promoting the dispersion of carbon black in the rubber matrix. Then, carbon black/rubber nanocomposites were prepared with different amount of M1. Because M1 could improve the dispersion of carbon black in the rubber matrix, the carbon black/rubber nanocomposites with M1 have lower network and loss factor, lower rolling resistance, and higher abrasion resistance, which is ideal to manufacture green bus and truck tires for energy‐saving, environment‐friendly, and low‐carbon society.
