“…Moreover, the polysulfide bonds in the asprepared coupling agent can react with the rubber matrix, resulting in an enhanced polymer-filler network. Some novel coupling agents also have special functionalities, such as an antioxygenic property [82][83][84][85][86] and an auxiliary vulcanizing property. [87][88][89][90] Besides silane coupling agents or liquid rubber derived from petrochemical industries, bio-based compounds can also be applied as modifiers to improve the dispersion behavior of silica in rubber matrices.…”

The concern regarding increasing oil consumption that originates from the high rolling resistance of automobiles has led to the development of green tires. The key enabling technique for preparing green tires involves the utilization of elastomer-silica nanocomposites. Elastomer-silica nanocomposites usually show low rolling resistance because of the intrinsic lubrication characteristics of siloxane and the excellent elastomer-modified silica interfacial interaction, making them ideal raw materials for a green tire. It is supposed that the comprehensive properties of rolling resistance can be further improved via continually optimizing the microstructures of elastomer-silica nanocomposites. Regulating silica dispersion, understanding the interface between elastomer and silica and building the quantitative correlation between the microstructure and the static/dynamic macro-mechanical properties are crucial in designing high-performance elastomer-silica nanocomposites. This review aims to summarize the recent progress of elastomer-silica nanocomposites from the point of view of silica dispersion, the elastomer-silica interface and the microstructure-mechanical connection, combining simulation and actual experimental findings. A short conclusion and an outlook on the current limitations and possible future research directions for constructing highperformance elastomer-silica nanocomposites for low-energy green tires are also presented.

“…In the rubber industry, nanoparticles such as carbon black (CB), silica, nanoclays, and carbon nanotubes are essential for mechanical reinforcement. After endowing the nanoparticles with different functions, they can exhibit synergistic effects in physical and chemical performance . Halloysite nanotubes (HNTs) are economically viable one-dimensional tubular aluminosilicate clays. − The inner and outer surfaces of the tubes consist of different substances, such as silica on the outer surface and an alumina layer in the interior. − Typically, halloysite nanotubes have a hollow tubular structure with an outer tube diameter of 40–60 nm and an inner diameter of 10–15 nm. , Furthermore, the different chemical properties of the inner and outer surfaces of halloysite nanotubes (HNTs) contribute to their surface decoration. , The hollow tubular structure of HNTs is used as a nanocontainer for the continuous release of chemical reagents and drugs.…”

The strategy of using sustainable biomass resources instead of traditional petrochemical products has been established as an environmentally friendly way to achieve the “green rubber” industry. Meanwhile, rubber antioxidants possessing high efficiency, long-lasting protection, migration resistance, and green multifunctional properties have attracted intensive investigation for rubber protection. Herein, a naturally extracted substance of tea polyphenol (TP)-functionalized halloysite nanotubes (HNTs), which generates the slow release of free-radical capturing activity and excellent interfacial interaction in the natural rubber matrix, is fabricated by vacuum-pumping and surface-decorating methods (denoted as HNTs-s-TP). Interestingly, the nontoxic and natural antioxidant HNTs-s-TP exhibited remarkable thermo-oxidative aging resistance and stability in a natural rubber (NR) matrix compared to that of TP directly pumped into the tubes due to the further modification of the chemical anchor TP on the outer surface of HNTs. In addition, we have systematically investigated the mechanism for highly efficient and sustainable antioxidation in the rubber matrix via the natural antioxidant HNTs-s-TP derived from the constructed galloyl structure. We envision that this new natural antioxidant fabrication technology will provide significant insights into the innovation for the construction of green and eco-friendly functionalized rubber additives.

“…For example, Xu et al 19 prepared SiO 2 /polyamide composites with enhanced tensile strength and attributed the significant performance improvement to the enhanced interfacial interaction. Zou et al 20 strengthened the interfacial interaction between SiO 2 particles and styrene–butadiene rubber by forming hydrogen bonds on the surface of SiO 2 , which significantly improved the tear strength and hardness of the composite. Zhao et al 21 used SiO 2 particles with diverse surface functional groups to increase the interfacial interaction between the SiO 2 particles and polyethylene oxide.…”
