Abstract:
1. A flexible heat sink article comprising: a base comprising a polymer; a plurality of polymeric protrusions extending away from the base, each protrusion having a major dimension and a minor dimension; and a thermal interface material contiguous with the base, wherein the polymer of the base comprises thermally conductive particles, wherein the polymer of the protrusions comprises non-spherical thermally conductive particles substantially aligned in the direction of the major dimension within the protrusions, wherein the thermal interface material is provided in two or more intermittent regions and includes two or more of a pressure sensitive adhesive, hot melt adhesive, low surface energy adhesive, epoxy, thermal bond film, phase change material, grease, and eutectic alloy phase change material, wherein the thermal interface material, and wherein the heat sink flexibility allows bending to a radius of less than about 30 cm at room temperature without significantly adversely affecting the heat sink function.
