Abstract
Giant nanomembranes that are characterized by aspect ratios (size/thickness)of greater than one million are dis-cussed.The combination of nanometer thickness and macroscopic size facilitates important applications in materialsseparation, selective transport and electrochemical devices. Their fabrication procedure and hybridization aredescribed here. Spin coating of precursor solutions on appropriate underlayer is effectively used to prepare 10-30 nmthick nanomembranes of metal oxides, interpenetrating network of crosslinked acrylate with metal oxide, and highlycross-linked organic polymers (epoxy resin, etc.). When the underlayer is removed, self-supporting nanomembranesbecome separated from the substrate without damage. These nanomembranes are surprisingly robust and defect-free, and can be hybridized by physical and chemical means. The latter method provides mechanical properties ofnanomembranes reveal that the texture of the nanomembranes is essentially identical with those of the macroscopiccounterparts. Their application potentials as 2D materials are discussed.
