▎ 摘  要

NOVELTY - Electromagnetic interference (EMI) shield (110) comprises (a) a substrate, (b) a metal-based conductive additive, and (c) a binder incorporated with the metal-based conductive additive and deposited as an EMI shielding coating on the substrate. USE - As electromagnetic interference shield. ADVANTAGE - The EMI shield has high thermal and electrical conductivity, efficiently dissipates heat energy and minimizes EMI interference, even at low thicknesses, is lightweight, exhibits excellent mechanical flexibility, structural integrity, and high corrosion resistance, withstands repeated bending without fatigue or performance degradation, enables the isolation of an electrical device from external radio frequency signals during testing and/or operation, and prevents radio frequency cross-talk or interference between two or more electrical device. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for the following: (1) an EMI shielding coating comprising a metal-based conductive additive, a binder, and a solvent incorporated with the metal -based conductive additive and binder to form the EMI shielding coating; and (2) a method for forming the EMI shield, comprising (a) forming a coating comprising a metal-based conductive additive, a binder, and a solvent,(b) depositing the coating on a substrate, and (c) drying the coating on the substrate to form an EMI shielding coating. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of the EMI shield.
