Abstract
Assemblies having multi-functionalities of any combination of heat spreading, absorption of stray radiation, signal focusing, and shielding are provided. The assemblies may include a heat spreading layer of at least one sheet of a compressed particles of exfoliated graphite, graphitized polymers and combinations thereof. The assemblies may also include at least one magnetic layer, which may provide the benefits of magnetic flux management and/or stray radiation absorption. The assemblies may include an optional plastic coating on one or both of the exterior surfaces. The assemblies may be used to enable fast wireless charging of electronic devices by efficiently focusing magnetic flux for better power transmission efficiency.
