Polymer and carbon origami structures are fabricated by first producing patterned sheets with less cross-linked compliant folds and more cross-linked stiff faces through differential UV exposure. The obtained patterned sheets are heated to further raise their compliance by increasing polymer chain mobility. These softened sheets with designated com...

The contrast in the material properties at the folds and the faces also enable the folding of the same final polyhedral shape from its multiple unfolded configurations, as shown in Fig. 3. The shapes that are made of polymers with carbon-rich back bones can be converted to an isometrically shrunken carbon through pyrolysis, as shown in Fig. ...
