“…SBR can easily undergo oxidation due to the instability of unsaturated double bonds and the presence of active allylic hydrogens of the butadiene units when exposed to thermal, oxidative or radiant conditions, which leads to scission of polymer chains. These reactions may lead to significant reduction in mechanical properties of the SBR, and eventually shorten service life of the composites …”

Poly‐p‐phenyleneterephthalamide is a broadly used aramid for the strengthening of materials. Nevertheless, its relatively inert surface is an obstacle for obtaining composites with enhanced properties. In this work, three ionic liquids (IL) were investigated as compatibilizers in the preparation of styrene‐butadiene rubber (SBR)‐aramid pulp composites. The composites were characterized using hardness and tensile tests, swelling, differential scanning calorimetry, and thermal gravimetric analysis, and also scanning electron microscopy. Aramid pulp treated with IL showed more fibrillation than the untreated pulp. The best characteristics were found for the composite with 5 phr of aramid pulp‐1 wt % of physisorbed IL, which showed the lowest swelling degree compared to the IL‐free SBR‐aramid composite (341% and 410%, respectively) and the highest tensile strength (2.48 MPa), 340% superior to that of SBR (0.73 MPa), and 25% superior to the IL‐free SBR‐aramid composite (2.05 MPa). Confirming the potential of imidazolium IL to be used as compatibilizers in SBR‐aramid composites. © 2018 Wiley Periodicals, Inc. J. Appl. Polym. Sci. 2018, 135, 46693.

“…The difference between M H and M L is often used to characterize the equivalent crosslinking density of the rubber. The equivalent crosslinking density reflects the interaction between the polymer and the filler, and the interaction inhibits the slip between the polymer chains and increases the stress at definite elongation of the material . It can be seen in Figure A that M H ‐ M L increases with the content of GNs, indicating the strong interaction between GNs and NR.…”

“…The equivalent crosslinking density reflects the interaction between the polymer and the filler, and the interaction inhibits the slip between the polymer chains and increases the stress at definite elongation of the material. [21] It can be seen in Figure 4A that M H -M L increases with the content of GNs, indicating the strong interaction between GNs and NR. GNs has a strong adsorption that will strongly adsorb the accelerator in the rubber, delaying vulcanization behavior.…”

Graphene nanosheets (GNs) were prepared by supercritical solvent intercalation method and cyclic stripping method under high pressure and stress. This “non‐chemical method” reduces impurities and avoids the destruction of graphene's intrinsic structure. In order to decrease the secondary stacking in processing, firstly GNs were dispersed in natural rubber (NR) latex to prepare NR/GNs concentrated master batch, and then combined with solid NR by mechanical blending. Since GNs have good dispersion in rubber matrix, a strong intermolecular force is formed between GNs and NR. Tensile strength, elongation at break, stress at 100% strain, stress at 300% strain, and tear strength of NR/GNs nanocomposites with 2 wt% GNs are enhanced 59.53%, 17.85%, 67.07%, 80.12% and19.20% respectively compared with NR. With more GNs, the NR/GNs nanocomposites exhibit lower Tg and better thermal stability. When the content of GNs in NR/GNs nanocomposites reaches 2 wt%, the Tg of nanocomposites drops about 2°C, and the remaining carbon at 600°C of nanocomposites increase by 3.07%. Moreover, It is demonstrated that the NR filled with 2 wt% GNs possess excellent thermal conductivity of 0.24 W m−1 K−1，which is a 50% increment compared with pure NR. Meanwhile, the electrical conductivity of the composites increases by four orders of magnitude than that of pure NR. These results clearly indicate that GNs can be expected to be manufactured at large scale and utilized in heat‐conducting and antistatic rubber.

“…The ID/IG of PPD-GO was 1.49, which was 0.24 higher than that of GO. This is because the amino group of PPD reacted with the oxygen-containing group on GO, resulting in the decrease of the average size of the sp 2 domain [30]. The intensity ratio (I D /I G ) of the D-peak to G-peak of the Raman spectra of graphene is commonly used to characterize the defect density of graphene [37][38][39][40].…”

Graphene oxide (GO) was modified by p-phenylenediamine (PPD), aiming at improving the wet-skid resistance and reduce the rolling loss of solution polymerized styrene-butadiene rubber (SSBR). PPD with amino groups enabled GO to obtain anti-aging function. The structure of modified GO (PPD-GO) was characterized by Fourier transform infrared spectroscopy (FTIR), X-ray diffraction (XRD) and Raman spectroscopy. Mechanical tests showed that the mechanical properties of SSBR before and after aging were improved by adding PPD-GO. The results of thermogravimetric-differential scanning calorimeter synchronization analysis (TGA-DSC) indicated that SSBR/PPD-GO obtained good thermo-oxidative stability. The dynamic mechanical analysis (DMA) of SSBR composites showed that the mechanical loss factor (tanδ) peak moved to high temperature with the content of PPD-GO. The tanδ values of SSBR composites showed that it had a good effect on improving the wet-skid resistance and reducing the rolling loss of SSBR by adjusting the content of PPD-GO. In particular, with the addition of 4 phr GO, SSBR was effectively improved in mechanical properties, aging resistance, wet-skid resistance and low rolling loss.
