Patent ID: 8440299

Claim:
An apparatus, comprising: a first electrode; and a layer of a composite dielectric material adjacent to the first electrode, wherein: the composite dielectric material comprises a first plurality of particle cores and a plurality of polymer strands; a polymer strand of said plurality is chemically bonded to a corresponding particle core via a first linker and comprises an interfacial core-shielding (ICS) group and a first polymer molecule; and the ICS group is chemically bonded to the first linker and to the first polymer molecule and comprises an aromatic moiety, wherein the aromatic moiety comprises a functional group selected from a set consisting of a metal complex of phenylpyrazole, a metal complex of dipivaloylmethanate, a derivative of chemically linked fluorene and triphenylamine, a derivative of poly(3,4-ethylenedioxythiophene), a derivative of poly(styrenesulfonate), a derivative of halogenated diphenyl ether, and a derivative of halogenated naphthalene.
