The current research has investigated the reinforcing effect of multi-walled carbon nanotubes (MWCNT) and graphene oxide (GO) on the properties of nanocomposites based on ethylene-propylene-diene monomer (EPDM) and carboxylated butadiene rubbers (XSBR, XNBR). According to the literature, in order to achieve the appropriate mechanical properties in EPDM rubber blends, it is necessary to use reinforcing fillers such as MWCNT and GO due to their excellent electrical and mechanical properties. Hence, they are ideal reinforcing agents for high strength polymer composites. Due to high saturation, it is very common to use coupling agents to create good interaction between the filler and the elastomeric chain. By adding carboxylated styrene butadiene rubber (XSBR) or carboxylated acrylonitrile butadiene rubber (XNBR) rubbers due to having carboxylic groups, the mechanical properties of EPDM increase. Because the presence of carboxyl groups in the EPDM/XSBR or EPDM/XNBR blends makes it compatible with mineralized fillers and increases its adhesion to polar surfaces. Also, in various studies, the effect of adding very small amounts of graphene has been studied and it has been found that due to its large surface area and high area-to-volume ratio, the rheological, mechanical and thermal properties of reinforced polymers are improved.
