Definitions

  • the present invention is related to solubilization of nonotubes, and more particularly to a polymer that is capable of solubilizing nanotubes.
  • a carbon nanotube can be visualized as a sheet of hexagonal graph paper rolled up into a seamless tube and joined.
  • Each line on the graph paper represents a carbon-carbon bond, and each intersection point represents a carbon atom.
  • carbon nanotubes are elongated tubular bodies which are typically only a few atoms in circumference.
  • the carbon nanotubes are hollow and have a linear fullerene structure.
  • the length of the carbon nanotubes potentially may be millions of times greater than their molecular-sized diameter.
  • SWNTs single-walled carbon nanotubes
  • MWNTs multi-walled carbon nanotubes
  • Carbon nanotubes are currently being proposed for a number of applications since they possess a very desirable and unique combination of physical properties relating to, for example, strength and weight. Carbon nanotubes have also demonstrated electrical conductivity. See Yakobson, B. I., et al., American Principle, 85, (1997), 324-337; and Dresselhaus, M. S., et al., Science of Fullerenes and Carbon Nanotubes, 1996, San Diego: Academic Press, pp. 902-905. For example, carbon nanotubes conduct heat and electricity better than copper or gold and have 100 times the tensile strength of steel, with only a sixth of the weight of steel. Carbon nanotubes may be produced having extraordinarily small size. For example, carbon nanotubes are being produced that are approximately the size of a DNA double helix (or approximately ⁇ fraction (1/50,000) ⁇ th the width of a human hair).
  • carbon nanotubes are well suited for a variety of uses, from the building of computer circuits to the reinforcement of composite materials, and even to the delivery of medicine. As a result of their properties, carbon nanotubes may be useful in microelectronic device applications, for example, which often demand high thermal conductivity, small dimensions, and light weight.
  • One potential application of carbon nanotubes that has been recognized is their use in flat-panel displays that use electron field-emission technology (as carbon nanotubes can be good conductors and electron emitters).
  • Electrode shielding such as for cellular telephones and laptop computers, radar absorption for stealth aircraft, nano-electronics (including memories in new generations of computers), and use as high-strength, lightweight composites.
  • carbon nanotubes are potential candidates in the areas of electrochemical energy storage systems (e.g., lithium ion batteries) and gas storage systems.
  • the “laser vaporization” technique utilizes a pulsed laser to vaporize graphite in producing the carbon nanotubes.
  • the laser vaporization technique is further described by A. G. Rinzler et al. in Appl. Phys. A, 1998, 67, 29, the disclosure of which is hereby incorporated herein by reference.
  • the laser vaporization technique produces carbon nanotubes that have a diameter of approximately 1.1 to 1.3 nanometers (nm).
  • Such laser vaporization technique is generally a very low yield process, which requires a relatively long period of time to produce small quantities of carbon nanotubes. For instance, one hour of laser vaporization processing typically results in approximately 100 milligrams of carbon nanotubes.
  • SWNTs single-walled nanotubes
  • Ni:Y;C graphite powder
  • SWNTs are produced as close-packed bundles (or “ropes”) with such bundles having diameters ranging from 5 to 20 nm.
  • the SWNTs are well-aligned in a two-dimensional periodic triangular lattice bonded by van der Waals interactions.
  • the electric arc technique of producing carbon nanotubes is further described by C. Journet and P. Bernier in Appl. Phys. A, 67, 1, the disclosure of which is hereby incorporated herein by reference. Utilizing such an electric arc technique, the average carbon nanotube diameter is typically approximately 1.3 to 1.5 nm and the triangular lattice parameter is approximately 1.7 nm.
  • the electric arc production technique is generally a very low yield process that requires a relatively long period of time to produce small quantities of carbon nanotubes. For instance, one hour of electric arc processing typically results in approximately 100 milligrams of carbon nanotubes.
  • the gas phase technique which produces much greater quantities of carbon nanotubes than the laser vaporization and electric arc production techniques.
  • the gas phase technique which is referred to as the HiPcoTM process, produces carbon nanotubes utilizing a gas phase catalytic reaction.
  • the HiPco process uses basic industrial gas (carbon monoxide), under temperature and pressure conditions common in modern industrial plants to create relatively high quantities of high-purity carbon nanotubes that are essentially free of by-products.
  • the HiPco process is described in further detail by P. Nikolaev et al. in Chem. Phys. Lett., 1999, 313, 91, the disclosure of which is hereby incorporated herein by reference.
  • the HiPco process may enable daily product of carbon nanotube in quantities of a pound or more.
  • the HiPco technique produces carbon nanotubes that have relatively much smaller diameters than are typically produced in the laser vaporization or electric arc techniques.
  • the nanotubes produced by the HiPco technique generally have diameters of approximately 0.7 to 0.8 nm.
  • Covalent side-wall functionalizations of carbon nanotubes can lead to the dissolution of carbon nanotubes in organic solvents. It should be noted that the terms “dissolution” and “solubilization” are used interchangeably herein. See Boul, P. J. et al., Chem Phys. Lett. 1999, 310, 367 and Georgakilas, V. et al., J. Am. Chem. Soc. 2002, 124, 760-761, the disclosures of which are hereby incorporated herein by reference. The disadvantage of this approach is that a carbon nanotube's intrinsic properties are changed significantly by covalent side-wall functionalizations.
  • Carbon nanotubes can also be solubilized in organic solvents and water by polymer wrapping. See Dalton, A. B. et al., J. Phys. Chem. B 2000, 104, 10012-10016, Star, A. et al. Angew. Chem., Int. Ed. 2001, 40, 1721-1725, and O'Connell, M. J. et al. Chem. Phys. Lett. 2001, 342, 265-271, the disclosures of which are hereby incorporated herein by reference.
  • FIGS. 1 A- 1 C show examples of such polymer wrapping of a carbon nanotube. In polymer wrapping, a polymer “wraps” around the diameter of a carbon nanotube. For instance, FIG.
  • FIG. 1 shows an example of polymers 102 A and 102 B wrapping around single-walled carbon nanotube (SWNT) 101 .
  • FIG. 1B shows an example of polymer 103 A and 103 B wrapping around SWNT 101 .
  • FIG. 1C shows an example of polymers 104 A and 104 B wrapping around SWNT 101 . It should be noted that the polymers in each of the examples of FIGS. 1 A- 1 C are the same, and the FIGURES illustrate that the type of polymer-wrapping that occurs is random (e.g., the same polymers wrap about the carbon nanotube in different ways in each of FIGS. 1 A- 1 C).
  • SWNT HiPco is the only SWNT material that can be currently produced at a large scale with high purity.
  • the present invention is directed to a method for solubilizing nanotubes, a polymer for solubilizing nanotubes, and resulting compositions of matter that may be formed using solubilized nanotubes.
  • Embodiments of the present invention provide a new approach to solubilizing nanotubes, such as carbon nanotubes, in solvents.
  • the solvents can be, in principle, any solvents. Solubilization of carbon nanotubes in accordance with embodiments of the present invention have been experimentally demonstrated in organic solvents and in water.
  • carbon nanotube surfaces are functionalized in a non-wrapping fashion by functional conjugated polymers that include functional groups for solubilizing such nanotubes.
  • non-wrapping means not enveloping the diameter of a nanotube.
  • associating a polymer with a nanotube in a “non-wrapping fashion” encompasses any association of the polymer with the nanotube in which the polymer does not completely envelope the diameter of the nanotube.
  • the non-wrapping fashion may be further defined and/or restricted.
  • a polymer can associate with a nanotube (e.g., via ⁇ -stacking interaction therewith) wherein the polymer's backbone extends substantially along the length of the nanotube without any portion of the backbone extending over more than half of the nanotube's diameter in relation to any other portion of the polymer's backbone.
  • Various embodiments provide polymers that associate with carbon nanotubes in a non-wrapping fashion. More specifically, various embodiments of polymers are provided that comprise a relatively rigid backbone that is suitable for associating with a carbon nanotube substantially along the nanotube's length, as opposed to about its diameter. In preferred polymers, the major interaction between the polymer backbone and the nanotube surface is parallel ⁇ -stacking. Such interaction may result in the polymer non-covalently bonding (or otherwise associating) with the nanotube.
  • rigid functional conjugated polymers that may be utilized in embodiments of the present invention include, without limitation, poly(aryleneethynylene)s and poly(3-decylthiophene).
  • the polymers further comprise at least one functional extension from the backbone, wherein such at least one function extension comprises any of various desired functional groups that are suitable for solubilizing a carbon nanotube.
  • a method of solubilizing a nanotube comprises mixing a polymer with a nanotube, and the polymer noncovalently bonding with the nanotube in a non-wrapping fashion, wherein the polymer comprises at least one functional portion for solubilizing the nanotube.
  • mixing is intended to encompass “adding,” “combining,” and similar terms for presenting at least one polymer to at least one nanotube.

For instance, an example molecular model of a polymer that associates (e.g., noncovalently bonds) with a carbon nanotube in a non-wrapping fashion is shown in FIGS. 2 A- 2 B.

  • SWNTs can be readily solubilized in CHCl 3 by mixing with 1 (e.g., 1a, 1b, 1c, or 1d), 2, 3, or 4 after vigorous shaking and/or bath-sonication.

  • SWNTs Hipco can be dissolved in 6.8 ml of CHCl 3 in the presence of 5.4 mg of 1a; and 20.4 mg of SWNTs HiPco can be dissolved in 4.0 ml of CHCl 3 in the presence of 20.4 mg of 1d.

  • R represents any organic functional group, such as R ⁇ OC 10 H 21 , R ⁇ C 10 H 21 , or other functional group described herein for solubilizing nanotubes, as examples.
  • the example backbones 5-15 are poly (aryleneethynylene)s, backbone 16 is a polyphenylene, backbone 17 is a polypyrrole, and backbone 18 is a polythiophene.
  • the 1-SWNTs HiPco solution of a preferred embodiment can mix homogeneously with other polymer solutions such as polycarbonate and polystyrene.
  • Homogeneous nanotube-polycarbonate and -polystyrene composites can be prepared by removing the organic solvents.
  • Soluble 1a-SWNTs HiPco complex significantly improves the mechanical properties of commercial polymers.
  • the tensile strength and break strain of pure poly(bisphenol A carbonate) are 26 MPa and 1.23%, respectively; 3.8 wt % of SWNTs HiPco filling results in 68% and 1800% increases in tensile strength (43.7 MPa) and break strain (19.1%) of poly(bisphenol A carbonate) (average M W approximately 64,000), respectively.

The solvent was quickly soaked away by the wiper, preventing the aggregation of nanotubes).
  • the scale bar shown in FIGS. 7 A- 7 B is 5 nm.
  • FIGS. 8 A- 8 C show high resolution TEM images of 1a-SWNTs arc (120 kV, one drop of the freshly prepared chlorobenzene solution of 1a-SWNTs arc (approximately 0.05 mg/ml) was placed on a Holey Carbon 400 mesh TEM grid (SPI Supplies, Formvar coating was removed) in contact with a Kimwipes wiper.

  • FIG. 9 shows field-emission SEM image (1.00 kV) of a torn edge of Bucky paper (1a-SWNTs HiPco ), illustrating that the majority of sample is SWNT nanoribbon.
  • the TEM images show that the majority of SWNTs in 1a-SWNTs laser and 1a-SWNTs arc are small ropes (2-6 nm, see FIGS. 6A, 6B, 7 A, 7 B, and 8 A- 8 C), whereas the majority of SWNTs in 1a-SWNTs HiPco are nanoribbon assemblies of small ropes (see FIGS. 6C, 6D, and 9 ).
  • FIGS. 6C, 6D, and 9 The observation of a twisted SWNT nanoribbon on TEM grid surface shown in FIG.
  • 6D is indicative of the robustness of such two dimensional (2D) assemblies and further supports a ⁇ -stacking interaction with the polymer backbone oriented along the nanotube's length.
  • Such nanoribbon is indicative of robustness because if the 2D assembly is not robust, it will easily collapse into small ropes on the TEM grid surface. It should be possible to prevent such 2D assembly and obtain small ropes and/or individual SWNTs HiPco by using 1, for example, with bulky and/or ionic functional groups in the end of the side chains.
  • embodiments of the present invention provide a molecular structure that is capable of noncovalently bonding with a nanotube (e.g., carbon nanotube) in a non-wrapping manner, and the molecular structure may comprise one or more functional groups for solubilizing the nanotube to which the molecular structure associates.
  • the molecular structure forms a non-covalent bond with the nanotube; however, in certain implementations the molecular structure may be such that it forms a covalent bond with the nanotube in a non-wrapping fashion.
  • Solubilization of nanotubes allows for their use in enhancing the properties of various compositions of matter, including, as one example, plastics.
  • Insoluble nanotubes cannot be dispersed homogeneously in commercial plastics and adhesives; therefore the polymer composites made by the addition of insoluble nanotubes gave little improvement in mechanical performance of plastics (Ajayan, P. M. et al., Adv. Mater. 2000, 12, 750; Schadler, L. S. et al. Appl. Phys. Lett. 1998, 73, 3842).
  • soluble nanotubes can significantly improve the mechanical performance of plastics, for example.
  • the tensile strength and break strain of pure poly(bisphenol A carbonate) are 26 MPa and 1.23%, respectively; 3.8 wt % of SWNTs HiPco filling results in 68% and 1800% increases in tensile strength (43.7 MPa) and break strain (19.1%) of poly(bisphenol A carbonate) (average M W approximately 64,000), respectively.
  • Nanotubes may be formed from various materials such as, for example, carbon, boron nitride, and composites thereof.
  • the nanotubes may be single-walled nanotubes or multi-walled nanotubes.
  • MWNTs multi-walled carbon nanotubes
  • boron nitride nanotubes and composites thereof.
  • nanotubes is not limited solely to carbon nanotubes. Rather, the term “nanotubes” is used broadly herein and, unless otherwise qualified, is intended to encompass any type of nanotube now known or later developed.
