摘要：

A method to prepare homogeneous aqueous suspension of chemically modified graphene sheet having good electrical conductivity, is presented. The control of chemistry of graphene oxide sheets can affect the properties of individual graphene sheets and graphene-based materials like composites and thin films. A highly conductive graphene composite was prepared by reducing chemically modified graphene oxide with polystyrene. The study used KOH to prepare an aqueous homogeneous suspension containing conducting chemically modified graphene sheets (CMG) from a precursor dispersion of graphene oxide in water. A chemical reaction of graphene oxide sheets suspended in water with KOH and hydrazine was performed during the experiment. A homogeneous suspensions of electrically conductive graphene sheets was prepared during the study.
