Abstract: A stretchable conductor includes a substrate with a first major surface and an elongate wire, wherein the substrate is an elastomeric material, the elongate wire is on the first major surface of the substrate, the wire includes a first end and a second end, and further includes at least one arcuate region between the first end and the second end. At least one portion of the arcuate region of the wire in the region has a first surface area portion embedded in the surface of the substrate and a second surface area portion unembedded on the substrate and exposed in an amount sufficient to render at least an area of the substrate in the region electrically conductive. The unembedded second surface portion of the arcuate region may lie above or below a plane of the substrate. Additionally, different methods of preparing said stretchable conductor are disclosed. Composite articles including said stretchable conductor in durable electrical contact with a conductive fabric are also disclosed.

Abstract: Described herein is an article comprising (i) bead film comprising a binder resin layer and a plurality of microspheres partially embedded in the binder resin layer such that a portion of the microspheres outwardly protrude a first distance from the surface of the binder resin layer; (ii) a stabilizing layer disposed on the outwardly protruding microspheres opposite the binder resin layer, wherein the stabilizing layer intimately conforms to the protruding microspheres, and wherein the stabilizing layer has a Tg less than 100 C and a storage modulus at 150° C. of at least 1.5 MPa; and (iii) a release agent, wherein (a) the binder resin layer comprises the release agent, (b) the stabilizing layer comprises the release agent, and/or (c) an intermediate layer comprises the release agent, wherein the intermediate layer is disposed between the monolayer of microspheres and the stabilizing layer, with the proviso that when the binder resin layer has a fluorine content along the polymeric backbone greater than 65 wt %, the stabilizing layer comprises a release agent selected from a silicone and a fluoropolymer. Also disclosed herein are methods of making thermoformable bead films.
