摘要:
The present invention provides a polymer/metal nano-composite. The nano-composite includes at least one copolymer chain having alkenyl monomer units and maleimide monomer units, and a nano-sized metal or inorganic crystal. It also provides a method of producing nano-sized metal/inorganic crystals in pure form. These nano-composites and nano-crystals can be useful as polymer fillers, tire rubber compounds, semiconductors, nano-magnets, catalysts, and quantum dots etc.

The present invention provides polymer nanoparticles with a controlled architecture of nano-necklace, nano-cylinder, nano-ellipsoid, or nano-sphere. The polymer nanoparticle comprises a core polymerized from multiple-vinyl-substituted aromatic hydrocarbons, a shell polymerized from alkyl-substituted styrene, and a polystyrene layer between the core and the shell. The present invention also provides a method of preparing the polymer nanoparticles and a rubber article such as a tire manufactured from a formulation comprising the polymer nanoparticles.

A polymer nano-particle composition is provided. The composition includes polymer nano-particles having a poly(alkenylbenzene) core and a surface layer comprising a crystalline polyolefin. The nano-particles preferably have a mean average diameter of less than about 100 nm.
摘要:
Compositions and methods for preparing at least partially hollow nanoparticles having an outer shell comprising a one or more molecules and/or residues derived from a metal soap, where the nanoparticles each comprise a continuous inner void space that averages at least 10 percent of the volume of each of the nanoparticles. Such at least partially hollow nanoparticles can be employed in a variety of applications including, but not limited to, tire manufacturing.
摘要:
A disk-like nanoparticle includes a core layer that comprises a cross-linked multi-vinyl substituted aromatic hydrocarbon and a shell layer that comprises tri-block copolymer chains, each having a first, a second, and a third block. The first and third blocks of the tri-block copolymer chains comprise vinyl aromatic monomer units and are crosslinked with the core. The second block comprises conjugated diene monomer units and comprises a top and bottom axial surface of the disk-like nanoparticle. In the case of a nanoparticle having A-B-C tri-block copolymer chains, the third block comprises a top and bottom axial surface of the disk-like nanoparticle.
