    Notes: Please ultrasonicate the single layer graphene dispersion before use.

    Dispersible Single Layer Graphene is prepared by completely reducing graphene oxide‚ which is prepared by the modified Hummer’s method. The commonly used prepare method creates a denser graphene which is subject to aggregations. The resulting graphene agglomerates are not soluble or redispersable in water or other polar solvents‚ and this makes further processing difficult. Our Dispersible Graphene avoids this problem and can be redispersed in many solvents.
