Thermal management materials

A thermal management assembly comprising:

• a first heat transfer surface;
• a second heat transfer surface opposing said first heat transfer surface;
• and
• a thermally-conductive interface interposed intermediate the first and said second heat transfer surface to provide a thermally-conductive pathway therebetween, the interface comprising a thermally-conductive compound formed into a layer which is conformable between the first and second heat transfer surface, the compound comprising an admixture of:
• (a) a thermal grease component;
• and
• (b) a dispersed component forming discrete domains within the thermal grease component, the domains being form-stable at normal room temperature in a first phase and conformable between the first and second heat transfer surface in a second phase, and the domains having a transition temperature above normal room temperature from the first phase to the second phase.
