“…The ratio of the intensity at the equator (I90°) to the intensity at the meridian (I0°) becomes larger during stretching for both FGS-filled SBR and NR samples indicating that FGS sheets are oriented along the stretching direction, whereas anisotropy is not observed for CB (Figure 5c). A comparative investigation on strain induced crystallization for graphene and carbon nanotubes filled natural rubber composites was also carried out by Fu et al [55] on composites prepared by ultrasonically-assisted latex mixing. The incorporation of graphene is shown to result in a faster strain-induced crystallization rate and a higher crystallinity compared to CNTs.…”

Carbon nanostructures including carbon black, carbon nanotubes, graphite or graphene have attracted a tremendous interest as fillers for elastomeric compounds. The preparation methods of nanocomposites that have a strong impact on the state of filler dispersion and thus on the properties of the resulting composites, are briefly described. At a same filler loading, considerable improvement in stiffness is imparted to the host polymeric matrix by the carbon nanomaterials with regard to that provided by the conventional carbon black particles. It is mainly attributed to the high aspect ratio of the nanostructures rather than to strong polymer-filler interactions. The orienting capability of the anisotropic fillers under strain as well the formation of a filler network, have to be taken into account to explain the high level of reinforcements. A comparison of the efficiency of the different carbon nanostructures is carried out through their mechanical and electrical properties but no clear picture can be obtained since the composite properties are strongly affected by the state of filler dispersion.

“…The dispersion and interface of the GE in the polymer composites is important and several reports have studied the mechanism on how GE reinforces the composites . In order to have a better understanding of the reinforcing mechanism of rGO–APMEL to rubber, the entanglement‐bound rubber tube (EBT) model was used to analyze the reinforcing effect of GE on NR/rGO–APMEL nanocomposites at a molecular level . The EBT model allows a proper separation of chemical crosslinks and physical constraint contribution to the stress–strain behavior and a reliable determination of crosslink densities .…”

“…G c is the elastic modulus corresponding to the crosslink constraint, and G e is entanglement modulus corresponding to the topological tube‐like constrain, which is closely related to the Mooney–Rivlin curves derived from the stress–strain curves by eqs. and

σ^{*} = \frac{σ}{normalα - α^{- 2}} = G_{c} + G_{e} f ((), α)

f ((), α) = 2 \frac{α^{\frac{normalβ}{2}} - α^{‐ normalβ}}{normalβ ((), α^{2} - α^{- 1})}, f ((), normalα = 1) = 1

where σ* is the reduced stress, σ is the nominal stress, α is the extension ratio, and β is an empirical constant which describes the relation between the deformed tube in the stretched state and an undeformed tube corresponding to the equilibrium state, β is generally taken as 1 …”

The simultaneous reduction and functionalization of graphene oxide (GO) was realized through a chemical grafting reaction with a functionalization agent N,N-bis(3-aminopropyl)methylamine (APMEL). The reduced and functionalized reduced GO (rGO-APMEL) sheets can be well dispersed in water without any added surfactant and the formed stable rGO aqueous dispersion can be kept for a long time, which can be used for the preparation of rubber-graphene (GE) composites by latex mixing. The electrostatic interaction between rGO-APMEL (positively charged) and natural rubber latex particles (negatively charged) leads to the formation of NR/rGO-APMEL composites with strong interaction. Compared with blank NR, the tensile strength and modulus for NR/rGO-APMEL increase with the rGO-APMEL loading. Especially, when the filler content is 5 phr, the tensile strength of NR/rGO-APMEL-5 increases by 32.7%, as a control the tensile strength of NR/GO-5 and NR/rGO-5 decrease by 20.1 and 15.6%, respectively. The entanglement-bound rubber tube model was used to analyze the reinforcing effect of GE on NR/rGO-APMEL nanocomposites at a molecular level. This study may provide us a novel approach to prepare well dispersed and exfoliated rGO-polymer nanocomposites.

“…6. Storage modulus; loss tangent for NR/NBR filled with 5 phr: Na-Mt; OMt; APT-OMt transfer between the components which leads to a marked increase in storage modulus and lesser damping characteristics due to reduced chain mobility [14]. By increasing temperature molecular movement at the interface of composites which contributes to the value of the damping property (tan δ), tends to increases, also molecular relaxation at high temperature loosens the molecular bonds, so E' value tends to decrease by increasing temperature.…”

Sodium montmorillonite (Na-Mt) was modified by cetyltriemethylammoniumbromide (CTAB) through cation exchange technique followed by grafting with 3-aminopropyltriethoxysilane (APT). The effects of organophillic surface treatments of montmorillonite on compatibilization of natural rubber (NR) /acrylonitrile butadiene rubber (NBR) blends was investigated. Physico-mechanical properties of rubber nanocomposites compatibilized with organomodified montmorillonite revealed strong nanocomposite with high tensile properties, impact strength and good resistance to flex fatigue, abrasion and compression set. Dynamic mechanical thermal analysis (DMTA) revealed a marked increase in storage modulus (E') and lesser damping characteristics of organically modified clay mineral polymer nanocomposites (CPN) due to intercalation of organophilic montmorillonite by rubber matrix. The morphology of the blends became homogeneous and smoother with the presence of exofoliated/intercalated organically modified montmorillonite. Organomodified layered silicate sheets of montmorillonite greatly enhanced barrier properties by creating tortuous path that retarded the progress of solvent molecules through rubber matrix.
