We present a new, simple, fast and energy efficient solvent-free protocol that allows the introduction of amides and amines onto graphene oxide (GO) at room temperature. This approach allows the functionalization of GO even with extremely reduced amounts of ammonia (NH3) gas and greatly expands the derivatisation routes to integrate graphene derivatives into devices and composite materials.
