Poly(phenylene sulfide) (PPS) is an attractive polymer as an engineering plastic due to its high mechanical strength and thermal stability. Herein, poly (phenylene sulfide)/nylon 6 grafted graphene oxide (PPS/NGO) nanocomposites were prepared, where NGO is prepared via ring-opening polymerization of ε-caprolactam onto the graphene oxide (GO), which has carboxylic acid groups that can act as an initiation group. Since nylon 6 is known to be blended with PPS, the nylon 6 moiety in NGO can increase mechanical properties PPS, especially resulting in PPS/NGO nanocomposites with improved toughness. Moreover, graphene nanosheets can provide improved mechanical strength and thermal stability to the polymer matrix because of their mechanical reinforcing and thermal barrier effects. These improved properties can be ascribed to the well-dispersed NGO in the PPS matrix, as confirmed by the morphology studies using SEM and EDS mapping analysis. |
