Abstract: Optical interlayers, laminated composites and improved methods for manufacturing the optical interlayers and laminated composites are provided. An optical interlayer film comprises at least one surface having an embossed surface pattern having at least two channels extending in at least two non-parallel directions. The channels have a depth of greater than about 20 ?m. The surface pattern allows for the removal of air between the interlayer and the outer laminate sheets, thereby establishing the requisite seal therebetween while minimizing premature edge sealing. The laminated composites are particularly useful for safety glazing in a variety of applications, such as automobiles, airplanes, trains, or other modes of transportation, display devices, windows in homes and other buildings, building facades, cabinets, and/or weight bearing architectural structures such as stairs and floors.

Abstract: A functional interlayer for incorporation into laminated structures is provided. The functional interlayer may provide solar control properties to the laminated structure. The laminated structure may be part of a window unit.

Abstract: Provided are electrolyte films or cells for use in variety of applications, such as electrochromic windows. An electrolytic film comprises a polymer layer, such as thermoplastic polyurethane or polymethyl methacrylate, and an electrolyte within the polymer layer. The electrolyte comprises a salt and a plasticizer. The plasticizer comprises one or more materials that are selected to provide sufficient conductivity and optical transparency for operation of the electrolyte film in an application requiring substantial optical clarity and switching speed, such as a smart window.
