ABSTRACT Ionic liquid modified multiwalled carbon nanotube (MWCNT) based styrene–butadiene rubber (SBR) nanocomposites were prepared with the two-roll mill mixing method, and the rheological measurements were used to study the dispersion of MWCNTs on a microscopic scale and its compatibility with the SBR matrix. Viscous liquid-like rheological behavior at low MWCNT loadings and pseudo-solid-like rheological response at high MWCNT loadings were observed, showing the gradual transformation from individual structures of MWCNTs to polymer bridged MWCNT networks. A decrease in the mobility of SBR macromolecular chains by the geometric confinement of three-dimensional networks of MWCNTs further confirms the interdeveloped pseudo-solid behavior of filled composites. Dynamic viscoelasticity data have been compared with the theoretical Carreau–Yasuda equation. Transmission electron microscopy of the samples reveals that MWCNTs are randomly dispersed in the rubber matrix. Finally the nature of the filler association and its role in the nonlinear viscoelastic properties at large strain amplitudes were investigated.

Ester-functionalized styrene-butadiene rubber (dibutyl itaconate-styrene-butadiene rubber) (D-ESBR) was synthesized by low-temperature emulsion polymerization using dibutyl itaconate (DBI) as a modified monomer containing ester groups. Nonpetroleum-based silica with hydroxy groups was used as a filler to enhance the D-ESBR, which can provide excellent mechanical properties, low rolling resistance, and high wet skid resistance. During the preparation of the silica/D-ESBR nanocomposites, a hydrogen-bonding interface was formed between the hydroxy groups on the surface of silica and the ester groups in the D-ESBR macromolecules. As the content of ester groups in the D-ESBR increases, the dispersion of silica in the nanocomposites is gradually improved, which was verified by rubber process analyzer (RPA) and scanning electron microscopy (SEM). Overall mechanical properties of the silica/D-ESBR modified with 5 wt % DBI were improved and became superior to that of the non-modified nanocomposite. Compared with the non-modified silica/D-ESBR, the DBI modified silica/D-ESBR exhibited a lower tan δ value at 60 °C and comparable tan δ value at 0 °C, indicating that the DBI modified silica/D-ESBR had lower rolling resistance without sacrificing wet skid resistance.

When designing rubber compounds for high-performance tires, increasing the silica content can improve the wet traction performance but decreases the fuel efficiency. This trade-off relation makes it difficult to improve the two factors simultaneously. One approach is the development of silica wet masterbatch (WMB) technology for producing compounds containing a high silica content with good dispersion. The technology involves a step to mix surface-modified silica and rubber latex. The technique requires a coagulant to break up the micelles of the rubber latex and cause the surface-modified silica and the rubber molecules to co-coagulate due to van der Waals forces. In this study, the effect of coagulant type on the characteristics of silica surface, and the mechanical properties of the emulsion styrene-butadiene rubber (ESBR)/silica WMB compounds was investigated, as well as the abrasion properties and the viscoelastic properties of the vulcanizates.
