Patent number: 10614958Abstract: 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.Type: GrantFiled: August 30, 2018Date of Patent: April 7, 2020Inventors: Eric Baer, Anne Hiltner, James S. Shirk, Mason Wolak, Zheng Zhou, Matthew Mackey, Joel Carr
