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.

“…To summarize, both CNMs and lanthanide derivatives are suitable objects for EPR studies [17][18][19][20]. The CNTs [21,22], nitrogen-doped CNTs [23], boron-doped CNTs [24], CNFs [25][26][27], consolidate of CNTs and CNFs [28][29][30][31], GO [32][33][34], graphene [35], GO aerogels [36,37], GO quantum dots [38], carbon nanofibers [39], glass-like carbon [40], detonation diamonds and NDs [12], graphitepolystyrene composite [41], carbon films [42], natural coals [43], oxidized coals [44], carbon blacks [45], different carbon composites [46] and others [18] were investigated using the EPR. EPR signals contain information about possible paramagnetic centers of CNMs, their nature and the possible influence of oxygen-containing groups [28,[47][48][49].…”

La2O3 nanoparticles stabilized on carbon nanoflake (CNF) matrix were synthesized and graphitized to produce core-shell structures La2O3/CNFs@C. Further oxidation of these structures by nitric acid vapors for 1, 3 or 6 h was performed, and surface-oxidized particles La2O3/CNFs@C_x (x = 1, 3, 6) were produced. Bulk and surface compositions of La2O3/CNFs@C and La2O3/CNFs@C_x were investigated by thermogravimetric analysis and X-ray photoelectron spectroscopy. With increasing the duration of oxidation, the oxygen and La2O3 content in the La2O3/CNFs@C_x samples increased. The electronic structures of samples were assessed by electron paramagnetic resonance. Two paramagnetic centers were associated with unpaired localized and mobile electrons and were registered in all samples. The correlation between bulk and surface compositions of the samples and their electronic structures was investigated for the first time. The impact of the ratio between sp2- and sp3-hybridized C atoms, the number and nature of oxygen-containing groups on the surface and the presence and proportion of coordinated La atoms on the EPR spectra was demonstrated.

Graphene oxide (GO) exhibits great application in rubber industry due to its unique two-dimensional nanosheet structure, signi cant speci c surface area, good barrier property, and high reactivity. However, different rubbers, such as carboxylated nitrile butadiene rubber (XNBR), natural rubber (NR), and styrene butadiene rubber (SBR), have different interactions with GO, which has great in uence on the reinforcement effect of GO to the rubber matrix. In this work, the enhancement mechanism of GO on NR, SBR, and XNBR was studied by combining experiments with molecular dynamics (MD) simulation. The results show that GO/XNBR nanocomposites had the smallest potential energy difference (ΔW a ), mean square displacement (MSD), and free volume fraction (FFV), resulting in excellent solvent resistance, and dynamic and mechanical properties. This study provides a new way to explore the macroscopic properties of rubber nanocomposites through molecular-level simulation.
