Patent number: 8691365Abstract: A composition includes an inorganic particle core and an initiator molecule chemically bonded thereto. The particle core is formed of a material having a dielectric constant of about fifteen or more. The initiator molecule includes a chain having about twenty or fewer carbon atoms and a phosphorous atom chemically bonded to an end of the chain. An alkyl derivative of an aryl moiety terminates another end of the chain.Type: GrantFiled: July 27, 2011Date of Patent: April 8, 2014Assignee: Alcatel LucentInventor: Ashok J. Maliakal

Patent number: 8440299Abstract: A composite dielectric material having a plurality of particle cores, each surrounded by polymer strands that are chemically bonded to the surface of the particle core. Each polymer strand includes a linker, through which the polymer strand is attached to the surface, an interfacial core-shielding (ICS) group bound to the linker, and a polymer molecule bound to the ICS group. The ICS groups are designed to inhibit electrical breakdown of the composite dielectric material by (i) deflecting or scattering free electrons away from the particle cores and/or (ii) capturing free electrons by being transformed into relatively stable radical anions. Representative examples of the particle core material, linker, ICS group, and polymer molecule are titanium dioxide, a phosphonate group, a halogenated aromatic ring, and a polystyrene molecule, respectively.Type: GrantFiled: February 25, 2010Date of Patent: May 14, 2013Assignee: LGS Innovations LLCInventor: Ashok J.
