  • 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.

  • Publication number: 20080169590
    Abstract: The invention relates to blends of polyamides in polyesters, a method for forming such compositions, and to containers made from such compositions. Specifically the compositions have less haze and transparency than previous blends. The blends can be used as passive gas barriers, and/or active oxygen scavengers with the addition of a transition metal catalyst. The invention seeks to obtain balanced refractive indices for the polyamides/polyester compositions. A method to blend the copolyester and polyamides and orient the blend to minimize the haze, thereby forming an oriented article, is also described and claimed. These articles have excellent gas barrier properties.

  • Patent number: 7255914
    Abstract: A new class of composite polymer films where the refractive index can be varied by simple compressive or extensive forces. The films are comprised of alternating layers of an elastomer and a glassy polymer or two different elastomers. When the layer spacing is much less than the wavelength of the probe light, these materials behave as effective medium composites. The layer thickness of the elastomer component and thus the effective index of the composite can be varied by compression, tension or shear.
