Formation of highly stable dispersions of silane-functionalized reduced graphene oxide

► Graphene oxide sheets were chemically functionalized with N-(trimethoxysilylpropyl) ethylenediamine triacetic acid and then reduced. ► The non-aqueous soluble reduced graphene oxide was converted to water-soluble by linked EDTA-silane. ► A well-layered structure EDTA-reduced graphene oxide film with high electrical conductivity has been prepared.
