The mechanical properties of non-vulcanized natural rubber reinforced with Graphene Oxide (GO) nanoplatelets have been studied by uniaxial deformations to evaluate the reinforcement efficiency of the filler. The nanocomposites are prepared by "latex-mixing" with aqueous dispersions of GO platelets, a procedure that requires no heat or chemical input and very little processing. The structure of the GO platelets was investigated by TEM. Tensile tests showed a significant increase in the Young's modulus of the composites even at low filler loading (<1 wt%). The viscoelastic properties of the nanocomposites are further investigated through relaxation tests. The nanocomposite shows significant improvements at much lower filler concentration than those usually achieved with carbon black or carbon nanotubes.
