Abstract: A multilayered composite shape memory material includes a coextruded first polymer layer of a first polymer material and a second polymer layer of a second polymer material. The composite shape memory material after thermomechanical programming being capable of undergoing at least one temperature induced shape transition from a temporary shape to a permanent shape. The first polymer layer defines a hard segment of the shape memory material that provides the shape memory material with the permanent shape, and the second polymer layer defines a switching segment of the shape memory material that provides the shape memory material with the temporary shape.

Abstract: A multilayer polymer dielectric film includes a stack of coextruded, alternating first dielectric layers and second dielectric layers that receive electrical charge. The first dielectric layers include a first polymer material and the second dielectric layers include a second polymer material different from the first polymer material. The first polymer material has a permittivity greater than the second polymer material. The second polymer material has a breakdown strength greater than the first polymer material. Adjoining first dielectric layers and second dielectric layers define an interface between the layers that delocalizes electrical charge build-up in the layers. The stack has substantially the crystallographic symmetry before and during receiving electrical charge.
