US Patent:

20090318641, Dec 24, 2009
Filed:

May 15, 2009
Appl. No.:

12/467196
Inventors:

Zhanhu Guo - Beaumont TX, US
H. Thomas Hahn - Malibu CA, US
Assignee:

THE REGENTS OF THE UNIVERSITY OF CALIFORNIA - Oakland CA
International Classification:

C08F 230/04
C08F 2/00
C08F 4/34
C08F 4/42
US Classification:

526 88, 526241, 526227, 526172, 977773, 977810
Abstract:

An improved method is provided to prepare reinforced resin nanocomposites without the need of surfactants or coupling agents. The present invention comprises the use of monomers for improving the dispersion of nano-sized materials and enhancing the particle/matrix interaction. One comprises mixing a plurality of nanoparticles with a monomer resin to form a mixture, blending a catalyst and a promoter with the mixture, and curing the blended mixture to form a polymerized nanocomposite. The monomers, which serve to stabilize the nanoparticles, are covalently bound onto the nanoparticle surface and copolymerize with non-bound monomers after introduction of a catalyst and a promoter that initiate polymerization. Without any additional surfactant or coupling agent, the resin is chemically bound onto the nanoparticle surface and protects the iron nanoparticles from agglomeration and oxidation.

Filed:

Nov 19, 2012
Appl. No.:

13/680464
Inventors:

Lamar University - Beaumont TX, US
ZHANHU GUO - Beaumont TX, US
Assignee:

LAMAR UNIVERSITY - Beaumont TX
International Classification:

B03C 1/00
US Classification:

427127
Abstract:

A nanocomposite material for use as an electromagnetic wave or radio frequency absorber or as a filter to trap or remove heavy metals. The nanocomposite material may be made with a one-pot synthesis, or thermodecomposition process, of magnetic graphene nanocomposites decorated with core-double-shell nanoparticles, wherein the double shell iron nanoparticles may comprise a crystalline iron core, an inner iron oxide layer around the crystalline iron core, and an outermost amorphous Si—S—O compound shell around the iron oxide layer.
