Hairuo Tu - Boxborough MA, US
Dmitry Fomitchev - Lexington MA, US
Jinsong Liu - Franklin MA, US
Zhifeng Li - Westford MA, US
James Boswell - Nashua NH, US
Assignee:
Cabot Corporation - Boston MA
International Classification:
G03G 9/08
US Classification:
4301081, 4301083, 4301087
Abstract:
The invention provides a toner composition comprising resin particles, a colorant, and a toner additive, wherein the toner additive comprises carbon-silica dual phase particles, wherein the carbon-silica dual phase particles comprise aggregates of carbon black comprising at least one silicon-containing region, and wherein the carbon-silica dual phase particles are distributed on the surface of the resin particles. The invention also provides a method of preparing the aforesaid toner composition.

Substantially Transparent Material For Use With Light-Emitting Device

View page
US Patent:
20080012032, Jan 17, 2008
Filed:
Jul 14, 2006
Appl. No.:
11/487030
Inventors:
Suhas Bhandarkar - Pleasanton CA, US
Zhifeng Li - Arlington MA, US
Assignee:
Cabot Corporation - Boston MA
International Classification:
H01L 33/00
US Classification:
257 94
Abstract:
The invention provides a substantially transparent material comprising particles of an inorganic titanate or an inorganic zirconate and at least one compound, wherein the particles are uniformly dispersed in the at least one compound, and wherein the particles are bonded to the at least one compound via at least one surface functional group of the particles. The invention also provides a light emitting device comprising a light emitting diode encapsulated with the substantially transparent material.

Filler System Including Densed Fumed Metal Oxide

US Patent:
20090163637, Jun 25, 2009
Filed:
Aug 14, 2008
Appl. No.:
12/228778
Inventors:
Zhifeng Li - Westford MA, US
William R. Williams - Reading MA, US
Michael P. Famiglietti - Haverhill MA, US
International Classification:
C09D 1/00
US Classification:
524413, 10628717, 10628734, 10628719, 10628718, 524432, 524430
Abstract:
A curable coating composition includes a polymer precursor and at least 6% by weight of a densed fumed metal oxide having a DBP number of at least 65% of the DBP number of an undensed fumed metal oxide of the same composition, surface area, and surface chemistry. The curable coating composition is at most 70% as viscous as a composition having the same components and the same weight fraction of the undensed fumed metal oxide.

Method Of Preparing A Nanoparticle Dispersion Of A Modified Metal Oxide

View page
US Patent:
20100216911, Aug 26, 2010
Filed:
Feb 25, 2010
Appl. No.:
12/712501
Inventors:
Dhaval A. Doshi - Lexington MA, US
Zhifeng Li - Westford MA, US
Assignee:
CABOT CORPORATION - Boston MA
International Classification:
C08K 9/04
US Classification:
523200
Abstract:
The present invention relates to a method of preparing polymer compositions comprising modified metal oxides in a polymer wherein a nanoparticle dispersion of a metal oxide in a non-aqueous solvent is combined with at least one coupling agent to form a nanoparticle dispersion of a modified metal oxide in the non-aqueous solvent. The nanoparticle dispersion is then combined with a polymer followed by the removal of the non-aqueous solvent or, alternatively, combined with a monomer, which is polymerized to form the polymer and removal of the solvent, in any order. Also disclosed are polymer compositions prepared by this method.

Porous Poly (Cyclic Olefin) Membranes

View page
US Patent:
20220362720, Nov 17, 2022
Filed:
May 6, 2022
Appl. No.:
17/738518
Inventors:
- Billerica MA, US
Pushkara Rao Varanasi - Poughkeepsie NY, US
Zhifeng Li - Acton MA, US
Carrie Lynn Frazee - Bedford MA, US
International Classification:
B01D 71/44
B01D 69/02
B01D 67/00
Abstract:
The disclosure provides certain porous membranes comprised of cyclic polyolefin polymers, such as poly(norbornene)s. In one embodiment, a poly(norbornene) polymer is dissolved in tetrahydrofuran, cast into a film and subjected to solvent induced phase separation to provide a porous filter membrane (i.e., film).
