Abstract: A method of forming a confined crystallization multilayer film includes coextruding a plurality of first polymer layers and a plurality of second polymer layer to form a multilayer film wherein each first polymer layer is sandwiched between second polymer layers and axially orienting the multilayer film at a temperature below the melting temperature (Tm) of the second polymer layer and to a thickness such that each first polymer layer forms a high aspect ratio substantially crystalline lamellae.

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.
