origami-like self-folding process is an intellectually stimulating
technique for realizing three-dimensional (3D) polyhedral free-standing
graphene oxide (GO) structures. This technique allows for easy control
of size, shape, and thickness of GO membranes, which in turn permits
fabrication of free-standing 3D microscale polyhedral GO structures.
Unlike 2D GO sheets, the 3D polyhedral free-standing GO shows a distinct
optical switching behavior, resulting from a combination of the geometrical
effect of the 3D hollow structure and the water-permeable multilayered
GO membrane that affects the optical paths.
