Abstract
The curing (optimum cure (tSUB90/SUB) and scorch time (tSUBs2/SUB), cure rate index (CRI), torque difference (ΔM), maximum torque (MSUBh/SUB) and minimum torque (MSUBl/SUB)), physical (hardness, rebound resilience, compression set and abrasion resistance), and mechanical properties (tensile strength, tensile modulus, tear strength and elongation at break) of ethylene-propylene-diene monomer terpolymer (EPDM)/styrene-butadiene copolymer rubber (SBR) nano-composites with additions of modified nano-graphene oxide (mGO) for possible usage as flexible and durable materials were examined in this study. Nano-graphene oxide (GO) was treated with two types of surfactants, 3-aminopropyltriethoxysilane (KH550) coupling agent and 4,4
