Graphene oxide and reduced graphene oxide are proposed as the primary construction materials for printed circuits of all kinds. Graphene oxide is an insulating, oxidized version of graphene, and its electrically conductive cousin, reduced graphene oxide, is derived by removing oxidizing molecules from graphene oxide. Thus far, the dielectric loss of flexible graphene oxide wafers has been measured by employing printed metal transmission lines and microwave measurement techniques. It has also been shown that using high powered excimer lasers conductive reduced graphene oxide traces can be printed directly onto graphene oxide wafers. Finally, it has been demonstrated that metallized graphene oxide wafers can be recycled by immersing the wafer in hot water, recovering the separated metals and dissociated graphene oxide, both of which can then be reused after further treatment.
