Abstract: Methods and apparatuses for applying liquid coatings are provided. A first roll (14), a second roll (16), and a nip (146) formed between the first and second rolls are provided. A coating liquid (22) is supplied to the nip. The coating liquid is smoothed, via the nip, into a substantially uniform layer (22a) of liquid coating which is transferred to a substrate (12). The second roll (16) includes a thin metal shell (40) and a resilient layer (30), the thin metal shell encases the resilient layer therebeneath, and the thin metal shell is capable of deflecting in unison with the resilient layer such that the thin metal shell is elastically deformable at the nip when in contact with the first roll (14).

Abstract: Lamination transfer films and methods for transferring a structured layer to a receptor substrate. The transfer films include a carrier substrate having a releasable surface, a sacrificial template layer applied to the releasable surface of the carrier substrate and having a non-planar structured surface, and a thermally stable backfill layer applied to the non-planar structured surface of the sacrificial template layer. The sacrificial template layer is capable of being removed from the backfill layer, such as via pyrolysis, while leaving the structured surface of the backfill layer substantially intact.

Abstract: A method includes placing an electronic device on a pliable mating surface on a major surface of a mold such that at least one contact pad on the electronic device presses against the pliable mating surface. The pliable mating surface is on a microstructure in an arrangement of microstructures on the major surface of the mold. A liquid encapsulant material is applied over the electronic device and the major surface of the mold, and then hardened to form a carrier for the electronic device. The mold and the carrier are separated such that the microstructures on the mold form a corresponding arrangement of microchannels in the carrier, and at least one contact pad on the electronic device is exposed in a microchannel in the arrangement of microchannels. A conductive particle-containing liquid is deposited in the microchannel, which directly contacts the contact pad exposed in the microchannel.

Abstract: A transfer article includes a carrier layer releasable at a release value of from 2 to 50 grams/inch from a release layer including a metal layer or a doped semiconductor layer. A functional layer overlies the carrier layer, and the functional layer includes at least one microcut inorganic layer. The microcut inorganic layer includes a pattern of cut toolmarks and plates bounded by the toolmarks, wherein each of the plates has a thickness of about 3 nanometers to about 2000 nanometers. The transfer article has a thickness of less than 3 micrometers.

Abstract: Film articles with dual-sided structures are ones in which both of the major surfaces of the film have a structured surface. The structured film articles have a first major surface and second major surface, where each surface has a plurality of spaced apart protrusions forming a repeating pattern. Each repeating pattern has a major axis, where the major axis is one of the major axes in the translational direction of the repeating pattern. The major axis of the repeating pattern on the second major surface forms an oblique angle with the major axis on the first major surface, where the angle is in the range of 10-90% of the angle of rotational symmetry of the repeating pattern. The structured film is a unitary substrate. The structured film articles are prepared by providing a flowable material composition having two major surfaces and simultaneously contacting the major surfaces with a first microstructuring tool, and a second microstructuring tool. Each microstructuring tool has a structured surface including a pattern of a plurality of depressions.
