摘要:
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 permanent or reversible one- or multiphoton, linear, nonlinear, or threshold optical writing processes to define data voxels within the active data storage layers that are readable by an optical reading device.
摘要:
A laminate structure for both packaging and non-packaging applications, including a five layer coextrusion composite containing an EVOH/polyolefin composite barrier layer coated or applied to a paper or paperboard substrate. The laminated structure may contain a layer of linear low density polyethylene or other layers, as needed for the application. The EVOH/polyolefin blend layer is preferably a blend of an ethylene vinyl alcohol copolymer having 44% ethylene moiety and a low density polyethylene polymer. The blend barrier, which is part of a five layer coextrusion composite layer provides improved oxygen and moisture barrier characteristics to a package, prepared from such a laminated structure, as well as improved rigidity and heat resistance, thereby providing longer shelf life and excellent flavor retention to the stored contents as well as improved dimensional stability to the cartons, package or containers, at a reduced cost.
摘要:
A multilayer nonlinear dielectric optical structure is formed by coextruding at least two polymeric materials, components (a) and (b), using a multiplying element; the structure contains a plurality of alternating layers (A) and (B) represented by formula (AB)x, where x=2n, and n is the number of multiplying elements; at least one of the components (a) and (b) exhibits nonlinear optical response. These structures perform a variety of nonlinear optical functions including all-optical switching and passive optical limiting.
