  • Publication number: 20130323519
    Abstract: A barrier film including a substrate, a base (co)polymer layer applied on a major surface of the substrate, an oxide layer applied on the base (co)polymer layer, and a protective (co)polymer layer applied on the oxide layer. The protective (co)polymer layer is formed as the reaction product of a first (meth)acryloyl compound and a (meth)acryl-silane compound derived from a Michael reaction between a second (meth)acryloyl compound and an aminosilane. The first and second (meth)acryloyl compounds may be the same. In some embodiments, a multiplicity of alternating layers of the oxide layer and the protective (co)polymer layer may be used. An oxide layer can be applied over the top protective (co)polymer layer. The barrier films provide, in some embodiments, enhanced resistance to moisture and improved peel strength adhesion of the protective (co)polymer layer(s) to the underlying layers. A process of making, and methods of using the barrier film are also described.

  • Patent number: 8298032
    Abstract: A multifunctional optical film for enhancing light extraction includes a flexible substrate, a structured layer, and a backfill layer. The structured layer effectively uses microreplicated diffractive or scattering nanostructures located near enough to the light generation region to enable extraction of an evanescent wave from an organic light emitting diode (OLED) device. The backfill layer has a material having an index of refraction different from the index of refraction of the structured layer. The backfill layer also provides a planarizing layer over the structured layer in order to conform the light extraction film to a layer of an OLED lighting device such as solid state lighting devices or backlight units. The film may have additional layers added to or incorporated within it to an emissive surface in order to effect additional functionalities beyond improvement of light extraction efficiency.

  • Publication number: 20120003451
    Abstract: An assembly that includes a barrier film interposed between a first polymeric film substrate and a first major surface of a pressure sensitive adhesive layer is provided. The first polymeric film substrate has a first coefficient of thermal expansion that is, in some embodiments, up to 50 parts per million per Kelvin. The pressure sensitive adhesive layer has a second major surface opposite the first major surface that is disposed on a second polymeric film substrate. The second polymeric film substrate is typically resistant to degradation by ultraviolet light. In some embodiments, the second polymeric film substrate has a second coefficient of thermal expansion that is at least 40 parts per million per Kelvin higher than the first coefficient of thermal expansion. The assembly is transmissive to visible and infrared light.
