A security marking has a physically unclonable function (PUF) wherein the PUF includes a disordered multilayer photonic crystal structure having an electromagnetic transmission and/or reflection spectrum and/or spectra upon receipt of electromagnetic radiation within a photonic bandgap region of the structure that is unique to the structure.

Multilayered structures and uses thereof in security markings

A method of producing high modulus and strength polymer materials includes compressive rolling a semicrystalline polymer material in at least two different axial directions of the material; and axially orienting at least a portion of the compressive rolled material to a draw ratio less than the ultimate elongation or the elongation % at break of the material.

High elastomeric modulus and strength polymer constructs and methods of forming

A method of forming particles for controlled guest agent release includes coextruding first and second polymer materials to form a multilayer polymer composite sheet comprising alternating first and second polymer layers, dividing the multilayer sheet into particles, immersing the particles in a solvent containing the guest agent such that the first layers swell and the guest agent is loaded into the swollen first layers.

Multilayer polymer composite constructs

A multilayered polymer composite film includes a first polymer material forming a polymer matrix and a second polymer material coextruded with the first polymer material. The second polymer material forms a plurality of fibers embedded within the polymer matrix. The fibers have a rectangular cross-section.

Production of micro- and nano-fibers by continuous microlayer coextrusion

A multilayered composite shape memory material includes a coextruded first polymer layer of a first polymer material and a second polymer layer of a second polymer material. The composite shape memory material after thermomechanical programming being capable of undergoing at least one temperature induced shape transition from a temporary shape to a permanent shape. The first polymer layer defines a hard segment of the shape memory material that provides the shape memory material with the permanent shape, and the second polymer layer defines a switching segment of the shape memory material that provides the shape memory material with the temporary shape.

Composite shape memory materials

A multilayered polymer composite film includes a water-soluble polymer matrix and a plurality of fibers embedded within the water soluble polymer matrix. The fibers include a water insoluble polymer material and at least one of a non-polymeric hydrophobic therapeutic agent or a non-polymeric hydrophobic cosmetic agent incorporated in the water insoluble polymer material. The fibers have a rectangular cross-section, and extend the entire length of the multilayered polymer composite film.

Polymer fiber scaffolds and uses thereof

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.

Multilayer polymer dielectric film

A polymer nanofiber scaffold includes a plurality of melt extruded nanofibers that are chemically modified to append surface functionality to the nanofibers.

Polymer nanofiber scaffolds and uses thereof

A multilayer film includes an extruded first polymer layer confined between extruded second polymer layers. The first polymer layer includes a high aspect ratio crystalline lamellae. The multilayer film is substantially impermeable to gas diffusion.

Confined crystallization multilayer films

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.
