The preparation of superhydrophobic graphene/melamine composite sponge applied in treatment of oil pollution

A facile chemical route to synthesize the graphene/melamine composite sponge with super oil adsorption capacity was reported. The effect of the graphene loading on the microstructures and adsorption property of the composite sponge was studied in detail. The adsorption capacity of diesel oil in composite sponge could reach 99.0 g/g. The oil adsorbed in composite sponge could be desorption in ethanol at 50 °C. Furthermore, the composite sponge exhibited excellent mechanical and environmental stability. The facile production, high stability, high adsorption capacity and recycling makes this material practically useful for the treatment of oil pollution in future.
