“…It is also demonstrated in Table 1 that significantly higher levels of stiffness and strength can be obtained by reinforcing natural rubber with GO than with carbon black. As well as increases in stiffness and strength there have also been recent reports of greatly improved fatigue resistance for the incorporation of only 1 phr of GO in natural rubber [187].…”

In the decade since the first isolation and identification of graphene, the scientific community is still finding ways to utilize its unique properties. The present review deals with the preparation and physicochemical characterization of graphene-based elastomeric nanocomposites. The processing and characterization of graphene and graphene oxide are described in detail, since the presence of such fillers in an elastomeric matrix affects dramatically the properties of the nanocomposite samples. Several preparation routes for the efficient dispersion of graphene in elastomers are then discussed, while aspects such as the interfacial bonding between the filler and the matrix or interactions between the fillers have been thoroughly analysed. Different types of graphene/elastomer nanocomposites are described in terms of their manufacture and properties and it has been shown that depending on the type of graphene employed and the preparation methods, the mechanical, thermal, electrical and barrier properties of the elastomeric matrix can be enhanced due to the presence of graphene, even at relatively-low filler loadings. In most cases, the formation of a filler network can play a major role in the improvement of the overall performance of the material.

“…There are a number of reports in the literature upon investigations into the mechanical properties of graphene-based/elastomer nanocomposites [112, 124- 185,187,194,195,[200][201][202][203][204]. In most cases some type of reduced graphene oxide was employed as the filler rather than graphene itself.…”

“…However, only few studies are available on NR latex-graphene nanocomposites [31], [32], [33], [34], [35], [36], [37]. The general approach to fabricate graphene-NR Latex nanocomposites involves dispersing GO into NR latex, in-situ reduction using reducing agents (e.g.…”

Commercially useful rubber products viz. gloves, condoms, tyres, and rubber hoses used in high temperature environments, etc., require efficient thermal conductivity, which increases the lifetime of these products. Graphene can fetch this property, if it is effectively incorporated into the rubber matrix. The great challenge in preparing graphene-rubber nanocomposites is formulating a scalable method to produce defect free graphene and its homogeneous dispersion into polymer matrices through an aqueous medium. Here, we used a simple method to produce defect free few layer (2–5) graphene, which can be easily dispersed into natural rubber (NR) latex without adversely affecting its colloidal stability. The resulting new composite showed large increase in thermal conductivity (480–980%) along with 40% increase in tensile properties and 60% improvement in electrical conductivity. This study provides a novel and generalized approach for the preparation of graphene based thermally conductive rubber nanocomposites.

“…The critical value of the Jintegral, assigned to crack initiation, was read at a CTOD of 0.1 mm. This threshold criterion is widely used [19,20]. Since Mullins-softening may have an influence on the fracture mechanical response [14], J-CTOD curves were also obtained from testing cyclically preloaded specimens.…”

To evaluate the performance of pyrolytic carbon black (pCB), we filled styrene-butadiene rubber (SBR) with pCB and N330 industrial carbon black (CB). We used two ratios of pCB and N330: 1/9 and 1/1. N330 was selected because its specific surface area was close to that of pCB. The overall CB content in the mixes was 0, 30, 45 and 60 part per hundred rubber (phr). We studied the effects of types and amounts of CB on the dispersion, cure behavior, dynamic mechanical thermal behavior, tensile mechanical and fracture mechanical properties of the filled rubbers. Dispersion of pCB was poorer than that of N330 CB. With respect to tensile mechanical properties -except tear strength -N330 outperformed pCB. The tear strength and fracture mechanics characteristics (J-integral at crack tip opening, and trouser tear strength) of SBR were higher with pCB than with N330. This can be attributed to the broader dispersion of pCB than N330. The combined use of N330 and pCB resulted in intermediate values reflecting the actual N330/pCB ratio for all measured parameters. We wanted to correlate the mechanical performance with the apparent molecular weight between crosslinks (Mc), and found reasonable correlations for the Payne effect, tensile strength and critical J-integral. On the other hand, we only found a tendency for tear characteristics; this was ascribed to additional effects of (p)CB dispersion.2
