Overall performance of natural rubber/graphene nanocomposites

Effect of graphene on polar and nonpolar rubber matrices

“…The wrinkled surface texture of the GO and rGO sheets in the composites is believed to ensure mechanical interlocking and load transfer in polymer composites (Hernández et al 2012;Rafiee et al 2010;Stankovich et al 2006). It is fascinating to observe that although the same compressive strain conditions have been imposed on the EPDM-GO/rGO based systems as seen in Fig.…”

“…Also, the results reported on elastomer-GSD composites by majority of researchers are controversial and mostly not consistent (Bai et al2011;Hernández et al 2012;Li et al 2013). For example, a recent study by Li et al (2013) and Hernández et al(2012) have confirmed that graphene sheets (GS) have shown a strong interaction with natural rubber.…”

Contrary to this, Bai et al(2011), Li, et al (2011, Kang et al(2014) and Allahbakhsh, et al(2013) have all emphasized that the numerous oxygen moieties (-OH, -O-C=O, and C-O-C etc) contained in graphene oxide (GO) sheets makes it compatible with rubber matrix, should the resulting properties be compared with those of reduced graphene oxide (rGO), which is a modified GS.…”

“…Mixing of the GO and rGO into the rubbers generally delayed t s2 especially for the GO filled compounds. The delay in t s2 was established to be caused by absorption of the cure accelerator by the oxygen moieties on the GO/rGO sheet (Hernández et al 2012;Mensah et al 2014;Mensah et al 2015;Rafiee et al 2010;Stankovich et al 2006). However, other factors such as; the acidic nature of the GO/rGO sheets, dispersion, wrinkling nature of the GS, thermal conductivity properties of GS, viscosity of the polymer, content of the curing ingredient (ZnO) used etc.…”

Modal Analysis of Nanoparticles Reinforced Natural Rubber

“…Few of these elastomers strain crystallize and the others require reinforcement to obtain the adequate static and dynamic characteristics. Natural Rubber (NR) and graphene nanocomposites increase the electrical conductivity and cause an important enhancement on the mechanical behavior of the NR [2]. Styrene-butadiene rubber/clay nanocomposite can enhance the modulus eight times at 300% strain and tensile strength seven times compared with cured pure rubber [3].…”
