Abstract
Polyamide 6 (PA6)/nitrile butadiene rubber (NBR) thermoplastic elastomers (TPEs) reinforced with graphene oxide were compounded by a two-step melt mixing process via an internal mixer. The effect of graphene oxide on tensile and impact strength was investigated. Samples containing 30 wt% of NBR, 0.5, 1.25, and 2 wt% of graphene oxide were produced. Increasing the graphene oxide content from 0.5 wt% to 2 wt%, increased the tensile strength from 63.6 MPa to 69.3 MPa, whereas impact strength decreased from 78.1 MPa to 75.3 MPa when graphene oxide content increased. The morphology study of prepared nanocomposites with scanning electron microscopy (SEM) shows that the size of NBR droplets in TPE nanocomposites reduces by adding of graphene oxide into the PA6 phase.
