“…Because of its obvious advantages such as high mechanical strength and elasticity of rubber products, it is widely used in tires, seals, damping, and expandable electronics [1][2][3]. Incorporation of fillers into elastomeric matrices is a recognized and effective strategy to fabricate high-performance rubber materials [4][5][6]. However, large affinity differences and weak interfacial interactions inevitably degrade the performance of fillers (such as carbon black and silica containing a large number of silica hydroxyl groups) dispersion homogeneity in the nonaffinity rubber matrix, thus limiting the dynamic and static mechanical properties of the nanocomposites [7][8][9].…”

The incorporation of fillers into the elastomer matrix is universally acknowledged as an effective strategy for fabricating superior-performance rubber materials, which depends on filler dispersion and interfacial interaction. In this work, styrene-butadiene rubber (SBR) with high modulus domains were prepared via the in situ reaction of epoxy resin (E51) and 4,4'-diaminodiphenylmethane (DDM) and a satisfactory mechanical properties reinforcement effect. The crosslinked network was confirmed by high-temperature infrared spectroscopy, vulcanization properties and activation energy. Scanning electron microscopy (SEM) demonstrated that the dispersed phase formed by the in situ reaction of E51 with DDM was uniformly dispersed in the matrix. Furthermore, with the loading of E51 from 5 phr to 15 phr, Atomic force microscopy (AFM) further confirmed that the size of the dispersed phase increased from 400 nm ~ 1 µm to 750 nm ~ 2 µm, and that the dispersed phase formed a high-modulus “domain” with low adhesion in the matrix, and the modulus increased from 90.1 MPa to 279.3 MPa, whereas the modulus of the SBR matrix was maintained at 11 ~ 15 MPa, and there was an interfacial layer with a thickness of 304 nm ~ 470 nm between the domain and the SBR matrix. At E51 loading of 15 phr, the 300% modulus, strength and fracture toughness of the specimen was significantly increased to 3.58 MPa, 6.34 MPa and 17.41 MJ/m3, respectively, which were 2.50, 3.30 and 3.03 times higher than those of SBR. The approach suggested in this research introduces an innovative method for reinforcing unfilled rubbers.

“…Different studies on rubber composites subjected to abrasive wear indicate that abrasion resistance depends on the material properties and external conditions such as contact velocity and applied pressure. [1][2][3] The right combination of different rubbers and reinforcing fillers can improve the abrasion resistance of rubber composites. 4 Despite exhibiting high elongation at break, high tensile strength and excellent resilience, natural rubber (NR) still has poor abrasion resistance.…”

The filler-rubber interaction and filler dispersion in natural rubber (NR) composites are important factors in determining mechanical properties. Herein, Molybdenum disulfide (MoS 2 ) and Al 2 O 3 -coated MoS 2 nanospheres are incorporated in NR/carbon black composites. The effects of MoS 2 and Al 2 O 3 -coated MoS 2 on the morphology, thermal and mechanical properties of the NR composites are investigated. The morphology analysis indicates that Al 2 O 3 -coated MoS 2 could greatly improve the dispersion of carbon black in NR composites. MoS 2 filler and carbon black show a synergetic effect on improving the properties of NR composites, leading to high abrasion resistance, tensile strength, elongation at break and expected dynamic mechanical properties. The thermal conductivity of NR composites increases with increasing the content of MoS 2 and Al 2 O 3 -coated MoS 2 . The thermal stability of the NR composites is also effectively improved by filling MoS 2 and Al 2 O 3 -coated MoS 2 . Furthermore, a small amount of Al 2 O 3 -coated MoS 2 significantly improves the abrasion resistance, wet grip and decreases rolling resistance of the composites. Al 2 O 3 -coated MoS 2 exhibits its potential application in green tires with good performance.

Incorporation of nanofillers (such as silica) into elastomer matrix is the most common strategy to prepare high‐performance rubber products. However, the poor dispersion of nanofillers in non‐affinity rubber materials and the weak interfacial interaction significantly limit the processing and mechanical properties. To reduce the polarity difference and enhance the interfacial interaction between silica and styrene butadiene rubber (SBR), we prepared a hydroxyethyl acrylate‐grafted SBR (SBR‐g‐HEA) through the redox initiator system, and subsequently fabricated SBR‐g‐HEA/silica nanocomposites by simple mechanical blending. The effects of reaction conditions on the grafting rate were studied in detail. ATR‐FTIR and 1H‐NMR collectively confirmed the successful grafting of HEA groups on SBR molecular chains, and the grafting fraction could be regulated from 0% to 2.5%. Scanning electron microscope (SEM) and rubber processing analyzer (RPA) showed that the incorporation of HEA could significantly improve the dispersion of silica nanoparticles in SBR matrix. Notably, the resulting SBR‐g‐HEA exhibited significantly enhanced attributes when compared to their unmodified counterparts, including superior mechanical properties, improved wear resistance, and reduced heat generation. The strategy proposed here provided insights toward the fabrication of non‐affinity rubber/filler nanocomposites for high‐performance rubber products and green tire.
