Studies on the morphology, tensile and tear attributes of ethylene propylene Diene monomer rubber nano composites reinforced with amine functionalized graphene nano platelets

Abstract

By blending on a two-roll mill, ethylene propylene Diene monomer rubber (EPDM) composites containing 0–20 phr amine functionalized graphene nano platelets (AGNP) were made and the dispersion of AGNP in the EPDM matrix was evaluated by using field emission scanning electron microscopy (FESEM).When compared to EPDM gum, the synthesized composites showed a notable improvement in mechanical properties.EPDM Nano composites with 15phr AGNP showed improvements in stress at rupture, elongation at failure, 100%modulus, strain, and tear resistance of 125%, 19%, 65.3%, 204%, and 5.7%, respectively. A homogeneous distribution of AGNP in EPDM, as shown by FESEM tests, can be attributed to this significant improvement. The prepared composites are intended to be used as anti-vibration mounts for automotive applications.
