Atomic Carbide Bonding Leading to Superior Graphene Networks

A versatile method for achieving atomic carbide‐bonded graphene networks on both metallic and non‐metallic substrates is described. This consists of vacuum‐assisted thermal exfoliation and floatation of functional graphenes at elevated temperatures, followed by deposition on substrates and in situ formation of carbide bonds. The cross‐linked graphene networks with an interlayer distance of angstroms exhibits a unique combination of unprecedented properties.
