Length-Based Liquid-Liquid Extraction Of Carbon Nanotubes Using A Phase Transfer Catalyst

View page
US Patent:
7578941, Aug 25, 2009
Filed:
Nov 29, 2005
Appl. No.:
11/289000
Inventors:
Kirk J. Ziegler - Gainesville FL, US
Daniel J. Schmidt - Troy MI, US
Robert H. Hauge - Houston TX, US
Richard E. Smalley - Houston TX, US
Assignee:
William Marsh Rice University - Houston TX
International Classification:
B01D 11/02
US Classification:
210639, 210708, 210737, 210738, 210774, 210787, 210806, 209 1, 423460, 423461, 204450, 977750, 977845, 977847
Abstract:
The present invention is generally directed to new liquid-liquid extraction methods for the length-based separation of carbon nanotubes (CNTs) and other 1-dimensional nanostructures. In some embodiments, such methods are directed to separating SWNTs on the basis of their length, wherein such methods comprise the steps of: (a) functionalizing SWNTs to form functionalized SWNTs with ionizable functional moieties; (b) dissolving said functionalized SWNTs in a polar solvent to form a polar phase; (c) dissolving a substoichiometric (relative to the amount of ionizable functional moieties present on the SWNTs) amount of a phase transfer agent in a non-polar solvent to form a non-polar phase; (d) combining the polar and non-polar phases to form a bi-phase mixture; (e) adding a cationic donor species to the bi-phase mixture; and (f) agitating the bi-phase mixture to effect the preferential transport of short SWNTs into the non-polar phase such that the non-polar phase is enriched in short SWNTs and the polar phase is enriched in longer SWNTs. In other embodiments, analogous methods are used for the length-based separation of any type of CNT, and more generally, for any type of 1-dimensional nanostructure.

US Patent:
8540959, Sep 24, 2013
Filed:
May 7, 2007
Appl. No.:
12/299634
Inventors:
Kirk J. Ziegler - Gainesville FL, US
Urs Rauwald - Bramen, DE
Robert H. Hauge - Houston TX, US
Howard K. Schmidt - Cypress TX, US
W. Carter Kittrell - Houston TX, US
Zhenning Gu - Sugar Land TX, US
Irene Morin Marek - Houston TX, US
Assignee:
William Marsh Rice University - Houston TX
International Classification:
D01F 9/12
US Classification:
4234476, 4234471, 423460, 977742, 977847
Abstract:
According to some embodiments, the present invention provides a method for attaining short carbon nanotubes utilizing electron beam irradiation, for example, of a carbon nanotube sample. The sample may be pretreated, for example by oxonation. The pretreatment may introduce defects to the sidewalls of the nanotubes. The method is shown to produces nanotubes with a distribution of lengths, with the majority of lengths shorter than 100 tun. Further, the median length of the nanotubes is between about 20 nm and about 100 nm.

US Patent:
20060159612, Jul 20, 2006
Filed:
Nov 22, 2005
Appl. No.:
11/285232
Inventors:
Kirk Ziegler - Gainesville FL, US
Jonah Shaver - Houston TX, US
Robert Hauge - Houston TX, US
Richard Smalley - Houston TX, US
Irene Marek - Houston TX, US
Assignee:
William Marsh Rice University - Houston TX
International Classification:
C01B 31/02
D01F 9/127
US Classification:
42344500B
Abstract:
The present invention is generally directed to methods of ozonating CNTs in fluorinated solvents (fluoro-solvents), wherein such methods provide a less dangerous alternative to existing ozonolysis methods. In some embodiments, such methods comprise the steps of: (a) dispersing carbon nanotubes in a fluoro-solvent to form a dispersion; and (b) reacting ozone with the carbon nanotubes in the dispersion to functionalize the sidewalls of the carbon nanotubes and yield functionalized carbon nanotubes with oxygen-containing functional moieties. In some such embodiments, the fluoro-solvent is a fluorocarbon solvent, such as a perfluorinated polyether.

Filed:
Feb 14, 2008
Appl. No.:
12/527317
Inventors:
Jason Edward Butler - Gainesville FL, US
Kirk Jeremy Ziegler - Gainesville FL, US
International Classification:
B07C 5/08

Type Separation Of Single-Walled Carbon Nanotubes Via Two-Phase Liquid Extraction

View page
US Patent:
20100166637, Jul 1, 2010
Filed:
Sep 15, 2006
Appl. No.:
12/066301
Inventors:
Kirk Jeremy Ziegler - Gainesville FL, US
International Classification:
D01F 9/12
B03B 5/62
US Classification:
4234471, 209208, 977742, 977750, 977751, 977845
Abstract:
The subject invention provides a two-phase liquid-liquid extraction process that enables sorting and separation of single-walled carbon nanotubes based on (n, m) type and/or diameter. The two-phase liquid extraction method of the invention is based upon the selective reaction of certain types of nanotubes with electron withdrawing functional groups as well as the interaction between a phase transfer agent and ionic moieties on the functionalized nanotubes when combined in a two-phase liquid solution. Preferably, the subject invention enables efficient, bulk separation of metallic/semi-metallic nanotubes from semi-conducting nanotubes. More preferably, the subject invention enables efficient, bulk separation of specific (n, m) types of nanotubes.

Separation Of Carbon Nanotube Bundles Via Interfacial Trapping

View page
US Patent:
20100326891, Dec 30, 2010
Filed:
Sep 12, 2008
Appl. No.:
12/677850
Inventors:
Kai-Wei Wang - Gainesville FL, US
Ryan David Reeves - Amherst MA, US
Kirk Jeremy Ziegler - Gainesville FL, US
Assignee:
UNIVERSITY OF FLORIDA RESEARCH FOUNDATION INC. - Gainesville FL
International Classification:
B03B 5/00
B82B 3/00
US Classification:
209132, 977845
Abstract:
In embodiments of the invention, bundles of carbon nanotubes are separated from individual nanotubes via interfacial trapping of bundled carbon nanotube bundles at an emulsion interface between suspension-phase and a solution-phase. The separation method comprises dispersing a mixture of individual and bundled carbon nanotubes in a solution comprising surfactant; adding at least one solvent to the surfactant solution to form a two-phase mixture; agitating the two-phase mixture to form an emulsion interface between the solution-phase and a suspension-phase, where nanotube bundles selectively segregate to the emulsion interface. Single-walled carbon nanotube suspensions exhibit strong fluorescence, which can be used to assess the degree of separation and determine if a repeated extraction of any remaining bundled carbon nanotubes remaining in the suspension-phase is desired. In another embodiment of the invention, separation of carbon nanotubes by type is carried out by interfacial trapping.
