Abstract
A thermally conductive medium includes a body with a first melting point and phase-changing material encapsulating a portion of the body, with the phase-changing material having a second melting point. The first melting point is greater than the second melting point, and the phase-changing material is configured to be in a liquid phase at temperatures above the second melting point and a solid phase at temperatures below the same. In the liquid phase, an adhesive force is present between the body and the phase-changing material due to capillary attraction, and the phase-changing material may be wettable to one of the two surfaces.
