  • Patent number: 10614958
    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.
