Patent number: 8530118Abstract: Methods of fabricating optical elements that are encapsulated in monolithic matrices. The present invention is based, at least in one aspect, upon the concept of using multiphoton, multi-step photocuring to fabricate encapsulated optical element(s) within a body of a photopolymerizable composition. Imagewise, multiphoton polymerization techniques are used to form the optical element. The body surrounding the optical element is also photohardened by blanket irradiation and/or thermal curing to help form an encapsulating structure. In addition, the composition also incorporates one or more other, non-diffusing binder components that may be thermosetting or thermoplastic. The end result is an encapsulated structure with good hardness, durability, dimensional stability, resilience, and toughness.Type: GrantFiled: August 21, 2009Date of Patent: September 10, 2013Assignee: 3M Innovative Properties CompanyInventors: Robert J. DeVoe, Catherine A. Leatherdale, Jeffrey M. Florczak, Patrick R. Fleming, John E. Potts

Patent number: 8298032Abstract: 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.Type: GrantFiled: June 1, 2011Date of Patent: October 30, 2012Assignee: 3M Innovative Properties CompanyInventors: John E. Potts, Fred B. McCormick, Martin B. Wolk, Jun-Ying Zhang, Terry L. Smith, James M. Battiato, Ding Wang, William A. Tolbert, Mark A. Roehrig, Clark I. Bright

Patent number: 7759042Abstract: Laser induced thermal imaging (LITI) donor films, and methods of preparing them, having a substrate, a light-to-heat conversion layer, and a pattern-directing layer. The pattern-directing layer can include patterns of self-assembled monolayer regions, hydrophilic and hydrophobic regions, positively or negatively charged regions, or a series of raised or recessed features. It can also be used to generate charge patterns and magnetic patterns. The pattern-directing layer causes patterning of a transfer layer applied to it, resulting in a templated transfer layer. When imaged, the LITI donor film transfers at least a portion of the templated transfer layer to a permanent receptor while maintaining the pattern substantially intact in the transferred portion.Type: GrantFiled: September 11, 2009Date of Patent: July 20, 2010Assignee: 3M Innovative Properties CompanyInventors: Martin B.
