Each repeating set of alternating layers may include an electrically conductive layer and a magnetic layer including a continuous layer of a magnetic material. The multi-layered material is generally configured to shield electromagnetic waves having a frequency of less than about 1 MHz. In various aspects, the electrically conductive layer may include a conductive metal layer, or a two-dimensional transitional metal carbide. The multi-layered material may be provided as a thin film, or can be shaped or sized as flakes for use with a resin composite that is deposited via a spray application technique. | 05-05-2022 |
