Process For The Preparation Of Nanostructured Materials

View page
US Patent:
7056455, Jun 6, 2006
Filed:
Apr 6, 2002
Appl. No.:
10/118519
Inventors:
Krzysztof Matyjaszewski - Pittsburgh PA, US
Tomasz Kowalewski - Pittsburgh PA, US
David N. Lambeth - Pittsburgh PA, US
James Spanswick - Wheaton IL, US
Nicolay V. Tsarevsky - Pittsburgh PA, US
Assignee:
Carnegie Mellon University - Pittsburgh PA
International Classification:
D01F 9/12
US Classification:
264 292, 4234471, 521 61, 521 62, 521 63, 521 77, 521918, 521919, 50252724
Abstract:
The present invention comprises a novel process for the preparation of carbon based structured materials with controlled topology, morphology and functionality. The nanostructured materials are prepared by controlled carbonization, or pyrolysis, of precursors comprising phase separated copolymers. The precursor materials are selected to phase separate and self organize in bulk, in solution, in the presence of phase selective solvents, at surfaces, interfaces or during fabrication, into articles, fibers or films exhibiting well-defined, self-organized morphology or precursors of well-defined, self-organized, bi- or tri-phasic morphology. Compositional control over the (co)polymers provides control over the structure of the phase separated precursor whose organization therein dictates the nanostructure of the material obtained after carbonization or pyrolysis, wherein each dimension of the formed structure can be predetermined. When the precursor morphology is selected to comprise cylindrical domains this procedure additionally allows for the direct formation of two dimensional nanowire grids or arrays of oriented nanostructures on surfaces. When these nanowire grids or arrays are perpendicularly oriented to the surface applications include field emitters, high surface area electrodes, electronic devices such as diodes and transistors, tools for AMF tips and elements of molecular electronics.

US Patent:
7332550, Feb 19, 2008
Filed:
Oct 10, 2003
Appl. No.:
10/684137
Inventors:
Krzysztof Matyjaszewski - Pittsburgh PA, US
Nicolay Tsarevsky - Pittsburgh PA, US
Assignee:
Carnegie Mellon University - Pittsburgh PA
International Classification:
C08F 20/06
C08F 20/04
C08F 4/44
C08F 4/72
US Classification:
526 91, 526 90, 526 93, 526 94, 526172, 5263171
Abstract:
This present invention is directed towards the identification or design, preparation, and use of suitable transition metal complexes for use as catalysts. The transition metal complexes may comprise heterodonor ligands. The present invention is also directed toward a method of determining the suitability of a transition metal complex for use in a catalytic reaction, such as, but not limited to, atom transfer radical polymerization (“ATRP”), atom transfer radical addition (“ATRA”), atom transfer radical cyclization (“ATRC”), and other catalytic redox reactions. The method assists in the approximate determination of the fundamental properties of the transition metal complex in a reaction media, such as, but not limited to, solubility, redox potential, stability towards acidic, basic, or ionic species, conditional radically transferable atom phylicity, and propensity toward disproportionation and therefore, the suitability of the complex to be used as a catalyst in the reaction media. The method provides a basis for prediction and evaluation of the properties of a transition metal complex for a particular selective catalytic reaction in a broad range of reaction environments. An understanding of the principles of the disclosed method allows a transition metal complex to be tuned to specific reaction medium by selecting a transition metal complex and ligand combination having the desired qualities.
