An electrically conductive bonding tape includes a conductive self-supporting first layer conductive in each of three mutually orthogonal directions and including conductive opposing first and second major surfaces, an conductive second layer coated on the first major surface of the self-supporting first layer and having at least 60% by weight of nickel, the second layer having an exposed major surface facing away from the first major surface of the self-supporting first layer and exposing at least some of the nickel in the second layer, and a conductive adhesive third layer bonded to the second major surface of the self-supporting first layer opposite the second layer. The adhesive third layer is conductive in at least one of the three mutually orthogonal directions and includes a plurality of conductive elements dispersed in an insulative material, at least some of the conductive elements physically contacting the self-supporting first layer.

Electrically conductive bonding tape with low passive intermodulation

A conductive adhesive film according to an embodiment includes: an adhesive base layer including first and second major surfaces facing each other; and a plurality of discrete individual particles distributed in the adhesive base layer, wherein outer surfaces of the particles are coated with metal at least in part to form metal coatings, and the metal coatings are connected with one another and are extended between the first and second major surfaces, such that an electrically and mechanically continuous three-dimensional porous network of the metal is formed.

Electrically conductive adhesive film and producing method thereof

An antenna includes a self-supporting electrically conductive wire having a width (W) and extending longitudinally along a length and between first and second ends of the conductive wire. The conductive wire forms one or more loops and comprises an electrically conductive layer disposed on and aligned with an adhesive layer. A width and a length of each of the conductive and adhesive layers are substantially co-extensive with the width and the length of the conductive wire.

Self-supporting antenna

A conductive double-sided tape includes a conductive, nonwoven adhesive layer including an adhesive material, a nonconductive, nonwoven substrate having a plurality of passageways, and a plurality of conductive particles penetrating through the nonconductive, nonwoven substrate and the adhesive material. The nonconductive, nonwoven substrate is embedded in the adhesive material. The conductive particles have a D99 particle size larger than a thickness of the nonconductive, nonwoven substrate and the adhesive material.

Nonwoven adhesive tapes and articles therefrom

Disclosed are polymer resins, including polymer resin sheets, having good electroconductivity and a method for manufacturing the same. The polymer resins exhibit flexibility and show electroconductivity on their surface as well as along their thickness, and thus can be used as electromagnetic wave-shielding materials having impact- and vibration-absorbing properties as well as conductivity.
