“…The varying ratio of nitrile within the polymer can change these characteristics. The addition of carbon containing fillers could enhance the processability and mechanical and many other properties of SBR [ 64 , 65 , 66 , 67 , 68 , 69 , 70 , 71 , 72 , 73 , 74 , 75 , 76 , 77 , 78 , 79 , 80 , 81 , 82 , 83 , 84 , 85 , 86 , 87 , 88 , 89 , 90 , 190 , 191 , 192 , 193 , 194 , 206 , 207 ].…”

The reinforcing ability of the fillers results in significant improvements in properties of polymer matrix at extremely low filler loadings as compared to conventional fillers. In view of this, the present review article describes the different methods used in preparation of different rubber nanocomposites reinforced with nanodimensional individual carbonaceous fillers, such as graphene, expanded graphite, single walled carbon nanotubes, multiwalled carbon nanotubes and graphite oxide, graphene oxide, and hybrid fillers consisting combination of individual fillers. This is followed by review of mechanical properties (tensile strength, elongation at break, Young modulus, and fracture toughness) and dynamic mechanical properties (glass transition temperature, crystallization temperature, melting point) of these rubber nanocomposites. Finally, Payne and Mullin effects have also been reviewed in rubber filled with different carbon based nanofillers.

“…It is usually applied as back coating of polypropylene fiber, orlon, and knotted carpet for soft and inflexible feel. Additionally, it also can be reinforced by different nanoparticles [21][22][23][24][25]. Our previous work focused on the influence of CNCs on the preparation and properties of xSBR films without addition of crosslinking agent [12].…”

This study aims to develop and characterize the nanocomposites using sulfur cross-linked carboxylated styrene-butadiene rubbers (S-xSBR) as the matrix and chitin nanocrystals (CNCs) as nanofillers. The composites' morphology and properties were examined by light transmittances, fourier transform infrared spectroscopy (FTIR), scanning electron microscope (SEM), X-ray diffraction (XRD), dynamic mechanical analysis (DMA), thermo gravimetric analyzer (TGA), and tensile properties determination. The addition of CNCs has slight effect on transparency of the composite films. FTIR data confirm the interfacial interactions between CNCs and S-xSBR via hydrogen bonds. CNCs are uniformly dispersed in the matrix from SEM result. The addition of CNCs can significantly improve the tensile strength and modulus both in static and dynamic states. The tensile modulus and tensile strength of S-xSBR/CNCs composites with the 4 wt.% CNCs is 62.5 % and 97.6 % higher than that of pure S-xSBR. The storage modulus, glass transition temperature, and the thermal stability of the composites are higher than those of the neat S-xSBR. The mechanical properties of the composite films are water-responsive, as the swollen samples exhibit obviously decreased strength and modulus. The greatest mechanical contrast is shown in the S-xSBR/CNCs composites with 2 wt.% CNCs loading whose tensile modulus decrease from 60.4 to 6.1 MPa after swelling equilibrium. The significant reinforcement effect of CNCs on S-xSBR is attributed to the unique structure of CNCs and the interfacial interactions in the composite.

“…As it will be seen in the next sections, the superior compatibility of XSBR with polar fillers like silica has led to a vast substitution of SBR latices with XSBR ones in preparing composites. Various fillers such as multiwall carbon nanotube (MWCNT), 41,42 halloysite nanotube (HNT), 43 silica, 34 cellulose nanocrystals, 44 organically modified boehmite, 45 layered silicates, 46 crab chitin, 47 soy protein, 48,49 wheat flours, 50 PS-encapsulated nanosilica, 51 and dual fillers such as silica/carbon black, 52 defatted soy flour (DSF)/carbon black, 53 and MWCNT/carbon black 54 are used to improve the physical and mechanical properties of XSBR. Having a look at the above-mentioned fillers it is found that many of them benefit from being the most abundant biorenewable material in the world as well as having low density, low energy consumption in manufacturing, the ease of being recycled by combustion, high sound attenuation, and comparatively nonabrasive nature which allows the ease of processing, large filling percentage, and consequently significant cost savings.…”

“…56 By consequence, the hydrogen bonding will be the prominent way of the interactions between the carboxyl and hydroxyl functional groups. 41,43 Regarding the higher mechanical properties resulting from chemical coupling of XSBR and fillers, efforts have been made to stimulate the possible esterification between the fillers and the XSBR functional groups. 43 Although there are a few approaches for efficient activating of carboxyl groups to react with hydroxyl groups in an aqueous media, 56,57 the risk of latex coagulation has strongly impeded such an ideology.…”

“…This method, in principal, begins with dispersing RAs in an aqueous surfactant solution by means of ultrasonication for instance followed by incorporating this dispersion to the polymer latex. The resulting aqueous nanocomposite may be solidified using freezedrying, 59 casting, 41 spray-drying, 60 etc. to a solid film containing dispersed RAs.…”

The present review focuses on the properties and developing applications of carboxylated styrene butadiene rubber (XSBR) as a modified grade of styrene butadiene rubber (SBR). Carboxylated polymers, and particularly carboxylated rubbers, are regarded as a new class of polymers with superior physical and mechanical properties over non-carboxylated counterparts. Upon introducing carboxyl groups, the properties such as elasticity range, strength, compatibility towards functional fillers and polymers, resistance to hydrocarbon solvents enhance and cross-linking by non-sulfur reagents becomes possible. The XSBR latex benefits from excellent mechanical and chemical stability, excellent liquidity, high bond and conjunction strength, high toughness and the strength after molding, low water absorption and air shrinkage, excellent durability, abrasion, oil and corrosion resistance of cement products. Due to the polarity offered by carboxyl groups, fiber, and particulate composites of XSBR exhibit improved physical and mechanical properties. The stable interface created between carboxyl group and the second polymer phase generally results in an enhancement for the host polymer.
