Claim 8:
9. A system, comprising:
a microelectronic die;
a heat spreader having a first surface adjacent the microelectronic die and a second surface opposite the microelectronic die; and
a composite material on one of the first surface or the second surface, the composite material comprising a polymer chain chemically bonded to a fill particle comprising a hexagonal lattice of carbon atoms, wherein the fill particle comprises an amine functional group having a first nitrogen atom directly bonded to a first carbon atom of the hexagonal lattice of carbon atoms, and wherein the polymer chain is covalently bonded to the fill particle via a second nitrogen atom directly bonded to a second carbon atom of the hexagonal lattice of carbon atoms.
