“…The self-lubricating nature of graphite and its modified forms can have a positive impact on the final properties of the rubber compounds as it has high surface area hence, can form good interaction among the fillers and matrix [15]. Xinwang Gu et.al reported that the hybrid rubber compounds with silica and graphene nanosheets (GNs) prepared through the simple high temperature exfoliation of expandable graphite can improve overall mechanical as well as conductivity property of the energy saving tyres [16]. Hybrid nano-micro filler composites were also reported for superior filler dispersion within NR vulcanizates [17].…”

The present study is proposing an eco-friendly, green tyre tread formulation possessing excellent output properties in terms of abrasion resistance, mechanical, rolling resistance and heat buildup properties. A standard formulation was prepared with a nominal amount of carbon black (CB) filler and tried to reduce the filler loading to a minimum value without compromising the performance characteristics. The simultaneous reduction in aromatic oil content also tried to make the formulation eco-friendly. To compensate for the effect of changes in the formulation a binary hybrid filler system was prepared by the partial replacement of CB using graphite. To ensure the maximum dispersion, a filler masterbatch of graphite was prepared within natural rubber matrix (NR) as (50/50) composition and incorporated into the compound master batch. The effect of thermal exfoliation of graphite on the dispersion thereby the performance of the composite was also analyzed. The graphite was thermally treated for a sudden thermal shock for 15 minutes at various temperatures ranging from 400–550 ˚C. Rolling resistance and heat build-up were recorded 45% and 53% reduction respectively for the formulations with thermally exfoliated graphite in comparison with the standard formulation. Abrasion resistance showed 18% improvement and significant improvement in mechanical and thermal properties are also reported.

Graphene and its derivatives have been confirmed to be among the best fillers for rubber due to their excellent properties, such as high mechanical strength, improved interface interaction, and strain-induced crystallization capabilities. Graphene rubber materials can be widely used in tires, shoes, high-barrier conductive seals, electromagnetic shielding seals, shock absorbers, etc. In order to reduce the graphene loading and endow more desirable functions to rubber materials, graphene-based hybrid fillers are extensively employed, which can effectively enhance the performance of rubber composites. This review briefly summarizes the recent research on rubber composites with graphene-based hybrid fillers consisting of carbon black, silica, carbon nanotubes, metal oxide, and one-dimensional nanowires. The preparation methods, performance improvements, and applications of different graphene-based hybrid fillers/rubber composites have been investigated. This study also focuses on methods that can ensure the effectiveness of graphene hybrid fillers in reinforcing rubber composites. Furthermore, the enhanced mechanism of graphene- and graphene derivative-based hybrid fillers in rubber composites is investigated to provide a foundation for future studies.

“…Silica‐filled rubber composites are obviously inferior in mechanical performance in compare to carbon black. At the same time, both silica and rubber are insulating materials and the antistatic and thermal conductivity of silica‐filled rubber composites are also obviously inferior 8–10 . At present, conductive fillers such as conductive carbon black, graphene, and carbon nanotubes are mainly added to rubber due to its high antistatic and thermal conductivity.…”

Graphene/carbon nanotubes and silica hybrids (CTGS) with high dispersion and strong interface were prepared by hydrogen bond self‐assembly technique using green modifiers Tween‐80 (TW) and Oleylamine (YA) as “molecular bridge.” CTGS was added into natural rubber (NR) as an effective functional filler to prepare high‐performance, low‐rolling resistance, and antistatic tire tread. In the vulcanization process of NR filled with CTGS (CTGS/NR), CTGS can participate in the rubber vulcanization, and co‐vulcanization is a catalyst for constructing the strong interfacial interactions between CTGS and rubber. The extreme dispersion of CTGS hybrid in NR and the strong interfacial interaction between CTGS and NR are the basis for obtaining excellent comprehensive properties of CTGS/NR composites. The results show that compared with NR filled with silica modified by triethoxysilyl propyldisulfide (ST@SiO2/NR), NR filled with carbon nanotubes and silica hybrid (CTGS4) using YA as the molecular bridge (CTGS4/NR) has the best comprehensive performance. Its tensile strength increased from 27.41 to 30.18 MPa, increasing by 10.1%, the rolling resistance decreased from 0.098 to 0.087, decreasing by 11.2%, and the conductivity increased by three orders of magnitude (increasing from 2.321 × 10−7 S∙m−1 to 4.111 × 10−5 S∙m−1) indicating excellent electrostatic conductivity for CTGS hybrid with carbon nanotubes loading as low as 0.6 wt%. CTGS hybrid is expected to be a new functional filler for rubber, especially good for green tires with high‐performance, low‐rolling resistance, and antistatic performances.
