The controlled assembly of nanomaterials has demon-strated significant potential in advancing technological devices.However,achieving highly efficient and low-loss assembly technique for nanomate-rials,enabling the creation of hierarchical structures with distinctive func-tionalities,remains a formidable challenge.Here,we present a method for nanomaterial assembly enhanced by ionic liquids,which enables the fabrication of highly stable,flexible,and transparent electrodes featuring an organized layered structure.The utilization of hydrophobic and non-volatile ionic liquids facilitates the production of stable interfaces with water,effectively preventing the sedimentation of 1D/2D nanomaterials assembled at the interface.Furthermore,the interfacially assembled nanomaterial monolayer exhibits an alternate self-climbing behavior,enabling layer-by-layer transfer and the formation of a well-ordered MXene-wrapped silver nanowire network film.The resulting composite film not only demonstrates exceptional photoelectric performance with a sheet resistance of 9.4Ωsq^(-1) and 93%transmittance,but also showcases remarkable environmental stability and mechanical flexibility.Particularly noteworthy is its application in transparent electromagnetic interference shielding materials and triboelectric nanogenerator devices.This research introduces an innovative approach to manufacture and tailor functional devices based on ordered nanomaterials. 展开更多

Silver nanowire(AgNW)networks hold great promises as next-generation flex-ible transparent electrodes(FTEs)for high-performance flexible optoelectronic devices.However,achieving large-area flexible AgNW network electrodes with low sheet resistance,high optical transmittance,and a smooth surface remains a grand challenge.Here,we report a straightforward and cost-effective roll-to-roll method that includes interface assembly/wetting-induced climbing transfer,nanowelding,and washing processess to fabricate flexible ordered lay-ered AgNW electrodes with high network uniformity.By manipulating the stacking number of the interfacially assembled AgNW monolayer,we can pre-cisely tailor and balance the transparency and the conductivity of the elec-trodes,achieving an exceptional Figure of Merit(FoM)value of 862.Moreover,the ordered layered structure enhances surface smoothness,compared with randomly arranged structures.To highlight the potential of these ordered lay-ered AgNW network electrodes in flexible optoelectronic devices,we success-fully employ them as highly sensitive strain sensors,large-area flexible touch screens,and flexible smart windows.Overall,this work represents a substantial advance toward high-performance FTEs over large areas,opening up exciting opportunities for the development of advanced optoelectronic devices. 展开更多
