ABSTRACT:
Provided is a flexible heat sink article comprising a base comprising a polymer and a plurality of polymeric protrusions extending away from the base, each protrusion having a major dimension and a minor dimension. The base comprises thermally conductive particles, and the protrusions comprise non-spherical thermally conductive particles substantially aligned in the direction of the major dimension within the protrusions. A thermal interface material may be provided contiguous with the base. Also provided is a flexible heat sink article comprising a base comprising a polymer and having a first surface and a second surface, a plurality of polymeric protrusions extending away from the first surface of the base, each protrusion having a major and a minor dimension, and a metallic layer contiguous with the second surface of the base, wherein the base and the protrusions comprise thermally conductive particles. Also provided is a method of making a flexible heat sink.
