Crystallization and Dynamic Mechanical Behavior of Graphene Nanoplatelets– Poly(ethylene-g-maleic anhydride) Nanocomposites

Poly(ethylene-g-maleic anhydride) (PEMA) graphene nanoplatelets (xGn) (PEMA–xGn) composites were prepared by melt mixing process in an internal batch mixer. It was observed that the increase of xGn in PEMA matrix up to 1 wt. % increased the modulus value. It was also revealed that the α-, β- and γ- transitions of the PEMA were affected by polymer chain branching and graphene nanoplatelets. These could be attributed to interactions and potentially bond formations between xGn and the maleic anhydride of PEMA as well as crystalline behavior of the nanocomposites
