Abstract: A filter includes a fibrous substrate having a plurality of coextruded first polymer material fibers and second polymer material fibers. Each of the first and second fibers are separated from each other and have a rectangular cross-section defined in part by an additional encapsulating polymer material that is separated from the first polymer material fibers and second polymer material fibers. The fibrous substrate has a pore size range of between about 0.1 μm to about 0.4 μm.

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.

Abstract: An optical information storage medium includes a multilayer film that includes a plurality of extruded alternating active data storage layers and buffer layers, which separate the active data storage layers. The active data storage layers and buffer layers have thicknesses that allow the active data storage layers to be writable by non-linear or threshold writing processes to define data voxels within the active data storage layers that are readable by an optical reading device.
