Abstract: Article (9,19) comprising a substrate (10, 20) comprising a polymer and having first (11,21) and second (12, 22) opposed major surfaces. The first major surface (11, 21) has first surface regions (13, 23) with first nanoparticles (14a, 14b, 14c, 14d, 24a, 24b, 24c, 24d) partially embedded into the first major surface (11, 21), and one of •(a) second surface regions (15) free of nanoparticles; or •(b) second surface regions (25) with at least second nanoparticles (28) on the first major surface (11, 21) or partially embedded into the first major surface (11, 21). The first surface regions (13, 23) have a first average surface roughness, Ra1, of at least 20 nm, wherein the second surface regions (15, 25) have a second average surface roughness, Ra2, of less than 100 nm, wherein the first average surface roughness, Ra1, is greater than the second average surface roughness, Ra2, and wherein there is an absolute difference between the first and second average surface roughness of at least 10 nm.

Abstract: A method of patterning a conductive layer to form transparent electrical conductors that does not require etching is disclosed. The method includes peeling a strippable polymer layer from a substrate coated with the conductive layer to pattern the conductive layer. In some embodiments, a resist matrix material is patterned over the conductive layer to prevent removal of the conductive layer beneath the resist matrix material. In other embodiments, a liner having a pressure sensitive adhesive surface is brought into contact with the patterned strippable polymer material to remove both the patterned strippable polymer material and the conductive layer beneath it.

Abstract: A composite article having a conductive layer on at least a portion of a flexible substrate. Electrical connectivity between various portions of the substrate can be obtained through this conductive layer. The conductive layer comprises a conductive surface, and there is a patterned layer on at least a portion of a first region of the conductive surface. The patterned layer comprises a conductive material having a surface roughness, and is in electrical contact with the conductive surface. An overcoat layer is present on at least a portion of the first region, such that the overcoat layer has a thickness less than the surface roughness, such that the conductive layer within the first region is covered by the overcoat layer, and such that at least a portion of the patterned layer substantially protrudes above the overcoat layer. The protruding portion permits electrical contact with the patterned layer, and via the conductive layer to other parts of the patterned layer and/or electrically conductive connectors to external electronic devices. Methods for forming the composite article are also disclosed. Methods of making such composite articles are also disclosed.

Abstract: Force-sensing capacitor elements and deformable membranes useful in electronic devices that include touch screen displays or other touch sensors. The deformable membranes, generally, include a first, second, and third layers with a first arrangement of a plurality of first structures interposed between the first and third layers and a second arrangement of one or more second structures interposed between the second and third layers. Electrodes may be included proximate to or in contact with one or more of the major surfaces of the first, second, and third layers or embedded within one or more of the second and third layers of the deformable membranes, yielding force-sensing capacitor elements. The electrodes proximate to or in contact with the one or more of the major surfaces of the first and second layers or embedded within one or more of the second and third layers may be one or more plurality of electrodes.

Abstract: The present disclosure provides an article having a substrate having opposing first and second surfaces. A conductor micropattern disposed on the first surface of the substrate. The conductor micropattern has a plurality of traces defining a plurality of cells. The conductor micropattern has an open area fraction greater than 80% and a uniform distribution of trace orientation. Each of the traces has a trace width from 0.5 to 10 micrometer. The conductor micropattern is a tri-layer material comprising in sequence a semi-reflective metal, a transparent layer, and a reflective layer disposed on the transparent layer.
