摘要:
Transfer films, articles made therewith, and methods of making and using transfer films that include embedded nanostructures are disclosed. The articles include a sacrificial template layer having a first surface and a second surface having a structured surface opposite the first surface and a thermally stable backfill layer applied to the second surface of the sacrificial template layer. The thermally stable backfill layer has a structured surface conforming to the structured surface of the sacrificial template layer and the sacrificial template layer comprises inorganic nanomaterials and sacrificial material. The sacrificial material in the sacrificial template layer is capable of being cleanly baked out while leaving a densified layer of inorganic nanomaterials on the structured surface of the thermally stable backfill layer.
摘要:
The present disclosure describes method of using nanostructured lamination transfer films for the fabrication of an OLED having a nanostructured solid surface, using lamination techniques. The methods involve transfer and/or replication of a film, layer, or coating in order to form a nanostructured surface directly on a photosensitive optical coupling layer (pOCL) that is in contact with the emitting surface of an OLED in, for example, a top emitting active matrix OLED (AMOLED) device. The pOCL layer is subsequently cured to form an optical coupling layer (OCL) and the nanostructured film tool removed to result in a nanostructured OLED.
摘要:
The present disclosure generally relates to patterned gradient polymer films and methods for making the same, and more particularly to patterned gradient optical films that have regions that include variations in optical properties such as refractive index, haze, transmission, clarity, or a combination thereof. The variation in optical properties can occur across a transverse plane of the film as well as through a thickness direction of the film.
摘要:
Retroreflective articles and constructions are disclosed. One exemplary retroreflective article or construction includes a retroreflective layer and a low refractive index layer. In one exemplary embodiment, the low refractive index layer is adjacent to at least a portion of a retroreflective structured major surface of the retroreflective layer.
