NOVELTY - Preparation of graphene-rubber composite, involves dispersing graphene in a dispersant to obtain a dispersion, admixing the dispersion with a latex, and drying the mixture. USE - Preparation of graphene-rubber composite used for adsorbing heavy metal ions and organic pollutants. ADVANTAGE - The method provides high-adsorption graphene-rubber composite having a three-dimensional channel with internal interconnection. The interaction between graphene layers and interlayer superposition phenomenon are weakened such that graphene is dispersed uniformly in rubber without reaggregation and without destruction of graphene structure, thus maintaining the performance of graphene material. The graphene-rubber composite not only has high oil absorption value, but also exhibits excellent adsorption capacity with heavy metal ions and organic pollutants in aqueous phase.
