Nanoarchitectonics of hyperbolic paraboloid 2D Graphene Oxide Membranes

Hyperbolic paraboloid surfaces or saddle-shaped materials can exist in two equilibrium shapes when the saddle shape reverses on itself and, therefore, be used as structural elements of new stimuli-responsive and shape-changing materials. Here we propose a fast easy approach to nanoarchitectonics graphene oxide nanosheets form curved interfaces. Our technology involves computer-aid design, three dimensional (3D) printing, casting templates for assembly two-dimensional (2D) nanosheets. We demonstrate feasibility our flakes, though it expanded include whole family 2D The prepared free-standing membranes show highly ordered nanostructure, typical flat multilayered optimize preparation conditions construct robust with nanostructured architecture controllable thickness curvature.
