Abstract
This paper presents a novel strategy for shape morphing of homogeneous plastic films into various free-standing 3D frameworks from their 2D precursors. The method involves programming plastic strain in the films during a peeling process. By modulating peeling parameters (adhesion energy, peeling speed, peeling direction, and deviation angle), diverse 3D geometries (millimeter to micrometer scales) are achieved. The strategy is applicable to various materials capable of plastic deformation and enables 4D transformations with responsive plastic films. Enhanced performance in 3D circuits and piezoelectric systems demonstrates the potential of this technique for 3D device fabrication.
