Classification: CPC H  C | IPC C  H

Claim 14:
15. A method, comprising:
applying a composite material over a microelectronic die, the composite material comprising a plurality of fill particles and a plurality of polymer chains, each of the plurality of fill particles comprising a hexagonal lattice of carbon atoms and one or more functional groups, wherein the one or more functional groups comprise a plurality of amine functional groups each having a nitrogen atom directly bonded to a corresponding carbon atom of the hexagonal lattice of carbon atoms; and
curing the composite material to chemically bond at least a first polymer chain of the plurality of polymer chains to at least a first fill particle of the plurality of fill particles via a first functional group of the first fill particle, wherein the first polymer chain is covalently bonded to the first fill particle via a first nitrogen atom directly bonded to a first carbon atom of the hexagonal lattice of carbon atoms.
