Abstract

A method for fabricating a shape memory polymer into a three-dimensional object is provided. The method includes forming a film of crosslinked poly(amic acid) on a substrate to provide a laminated substrate; forming the laminated substrate into a first configuration that is in a three-dimensional form; curing the cross-linked poly(amic acid) to provide the shape memory polymer having a permanent shape corresponding to the first configuration; and removing the substrate from the laminated substrate to provide the three-dimensional object comprising the shape memory polymer. The formation of the laminated substrate into the three-dimensional object may be based on origami techniques.
