An optical metasurface film includes a flexible polymeric film having a first major surface, a patterned polymer layer having a first surface proximate to the first major surface of the flexible polymeric film and having a second nanostructured surface opposite the first surface, and a refractive index contrast layer including a refractive index contrast material adjacent to the nanostructured surface of the patterned polymer layer forming a nanostructured bilayer with a nano structured interface. The nanostructured bilayer comprising a plurality of nanostructures disposed on the flexible polymeric film. The nanostructured bilayer imparts a light phase shift that varies as a function of position of the nano structured bilayer on the flexible polymeric film. The light phase shift of the nanostructured bilayer defines a predetermined operative phase profile of the optical metasurface film. A light reflecting layer is in optical communication with the nano structured bilayer.

Reflective optical metasurface films

Nanostructured articles, materials for the nanostructured articles, and intermediate articles for use in making the nanostructured articles. The nanostructured articles can be formed on a flexible film and are useful for optical metasurface applications and possibly other applications. The articles can include nanoreplicated layers or pattern transfer layers of engineered nanostructures.

Nanostructured optical films and intermediates

Materials and methods useful in forming nano-scale features on substrates, and articles such as optical films incorporating such nano-scale patterned substrates.

Materials and methods for forming nano-structures on substrates

An optical metasurface film includes a flexible polymeric film having a first major surface, a patterned polymer layer having a first surface proximate to the first major surface of the flexible polymeric film and having a second nanostructured surface opposite the first surface, and a refractive index contrast layer adjacent to the nanostructured surface of the patterned polymer layer forming a nanostructured bilayer with a nanostructured interface. The nanostructured bilayer acts locally on amplitude, phase, or polarization of light, or a combination thereof and imparts a light phase shift that varies as a function of position of the nano structured bilayer on the flexible polymeric film. The light phase shift of the nanostructured bilayer defines a predetermined operative phase profile of the optical metasurface film.

Optical metasurface films

A substantially planar self-folding film assembly to generate a folded three-dimensional assembly. The assembly includes a flexible support substrate, adhesive elements, and folding members. The folding members include a base, a folding region, and a hinge adjacent each folding region attached at the base to the flexible support substrate by at least one of the adhesive elements. An array of polymer actuators is co-extensive, or shaped to be not co-extensive, with each of the flexible folding members. Upon activation by a patterned light to heat conversion layer, each polymer actuator is designed and configured to provide a displacement of the corresponding flexible folding member about each hinge.

The transfer films may include a plurality of co-extensive electrical protolayers forming an electrical protolayer stack, at least selected or each protolayer independently exhibiting a complex viscosity of between 10and 10Poise at a shear rate of 100/s when heated to a temperature between its Tand T.

Electrical multilayer lamination transfer films

Transfer films, articles made therewith, and layer-by-layer methods of making and using transfer films to form an inorganic optical stack are disclosed.

Layer-by-layer assembled multilayer lamination transfer films

The present disclosure provides lamination transfer films and use of the lamination transfer films, particular in the fabrication of architectural glass elements, such as those used in Insulated Glass Units (IGUs). The lamination transfer films may be used to transfer functional layers and structures. The lamination transfer films may include a support film that can be removed during the transfer process, and the transferred materials are primarily inorganic. The resulting transferred structures on glass generally have high photo- and thermal-stability, and therefore can successfully be applied to the glass surfaces that are interior to the cavity within an IGU. The lamination transfer films can also be patterned such that macroscopic patterns of microoptical elements can be applied on a glass surface.

Microoptics for glazing

The present disclosure relates to micro-optical assemblies containing at least one optical element adhered to a receptor substrate, e.g. a transparent receptor substrate, the receptor substrate contains at least one graphics layer. The micro-optical assemblies include both functional micro-optical structures that can alter, for example, incident light, and a graphic layer, which includes at least one graphic, e.g. a graphic design, which may include color, patterns, imagery, indicia and the like. The combination of the micro-optical elements with the graphic of the graphics layer can provide unique light altering assemblies that have graphic designs that may be functional, e.g. to display a message, and/or have aesthetic value. The micro-optical assemblies of the present disclosure are useful in a variety of applications which include, but are not limited to, display and graphics applications and architectural glass applications. The present disclosure also provides a method of making the micro-optical assemblies of the present disclosure.
