Definitions
- This invention provides a method for preparing a carbon nanotube/polyaniline dispersion.
- Carbon nanotubes have a number of electronic and dimensional attributes that are being exploited in the development of novel compositions for use in electronic devices and other fields of use.
- CNTs have been incorporated into the conductive layer of organic thin film transistors to enhance the performance of these devices.
- WO 03/069032, WO 03/106600, WO 03/050332, and EP 1 ,336,672 disclose the use of dispersion aids to disperse CNTs.
- EP 1 ,061 ,040 discloses a process for purifying carbon nanotubes, in which washed carbon nanotubes are passed through a metal mesh filter having a mesh size of 300 microns or less.
- CNTs are often used in mixtures containing other materials, such as polymers, and methods that are useful for forming CNT dispersions may not provide adequate dispersions of CNTs in more complex mixtures.
- This invention provides a method for preparing a carbon nanotube/polyaniline dispersion, comprising: a. sonicating a first mixture comprising: carbon nanotubes; a first solvent selected from a group consisting of chlorinated and non-chlorinated aromatic solvents, chlorinated and non-chlorinated aliphatic solvents, C4-C10 alcohols and C4-C10 ethers; and a dispersion aid selected from a group consisting of polyamine amides, polymers with tertiary amine affinic groups, polymers with ethylene oxide and hydroxy affinic groups, unsaturated polycarboxylic acid polymers, alkyl ammonium salts of polycarboxylic acids, and carboxylic acid salts of polyamine amides, to form a dispersion of carbon nanotubes; and b.
- sonicating a second mixture comprising: the dispersion of carbon nanotubes, polyaniline, xylenes and a second solvent selected from a group consisting of 2-butoxyethanol, 1-butanol, 1-hexanol and diethylether.
- This invention also provides a composition
- a composition comprising: a. carbon nanotubes; b. a dispersion aid selected from a group consisting of polyamine amides, polymers with tertiary amine affinic groups, polymers with ethylene oxide and hydroxy affinic groups, unsaturated polycarboxylic acid polymers, alkyl ammonium salts of polycarboxylic acids, and carboxylic acid salts of polyamine amides; and c. polyaniline.
- FIGURES Figure 1 is an SEM image of a coating of CNTs in DNNSA-doped PANI prepared using Disperbyk®163 as a dispersion aid.
- Figure 2 is an SEM image of a coating of CNTs in DNNSA-doped PANI prepared without a dispersion aid.
- Dispersion Process This invention provides a method for preparing a carbon nanotube/polyaniline dispersion comprising: a.
- sonicating a first mixture comprising: carbon nanotubes; a first solvent selected from a group consisting of chlorinated and non-chlorinated aromatic solvents, chlorinated and non-chlorinated aliphatic solvents, C4-C10 alcohols and C4-C10 ethers; and a dispersion aid selected from a group consisting of polyamine amides, polymers with tertiary amine affinic groups, polymers with ethylene oxide and hydroxy affinic groups, unsaturated polycarboxylic acid polymers, alkyl ammonium salts of polycarboxylic acids, and carboxylic acid salts of polyamine amides, to form a dispersion of carbon nanotubes; and b.
- a first solvent selected from a group consisting of chlorinated and non-chlorinated aromatic solvents, chlorinated and non-chlorinated aliphatic solvents, C4-C10 alcohols and C4-C10 ethers
- a dispersion aid
- the second mixture can further comprise dinonylnaphthalene sulfonic acid, DNNSA.
- PANI-DNNSA solutions can be prepared by an emulsion process.
- the dispersion process of this invention can be conducted using single-walled CNTs, multi-walled CNTs, or mixtures thereof.
- Suitable organic solvents for the initial dispersion of carbon nanotubes include non-polar as well as somewhat polar organic solvents, such as non-chlorinated aromatic solvents, non-chlorinated alkanes, chlorinated aromatics, chlorinated alkanes, alcohols (C4-C10) and ethers.
- solvents examples include toluene, benzene, xylenes, chlorobenzene, dichlorobenzene, dichloroethane, hexane, cyclohexane, 2- butoxyethanol, 1-butanol, 1-hexanol and diethylether.
- Xylenes, or a mixture of xylene isomers are preferred.
- the preferred dispersion solvent also comprises xylenes and at least one of 2-butoxyethanol, 1-butanol, 1-hexanol and diethylether.
- Suitable dispersion aids are selected from a group consisting of polyamine amides, polymers with tertiary amine affinic groups, polymers with hydroxy affinic groups, unsaturated polycarboxylic acid polymers, alkyl ammonium salts of polycarboxylic acids, and carboxylic acid salts of polyamine amides.
- Preferred dispersion aids include:
- Disperbyk®107 poly(carboxylic acid ester) with tertiary amines and hydroxy affinic groups
- Disperbyk® 108 poly(carboxylic acid ester) with tertiary amines and hydroxy affinic groups
- Disperbyk®130 a solution of polyamine amides of unsaturated carboxylic acids
- Disperbyk®163 a polyurethane with tertiary amine affinic groups
- Byk®345 a polyether modified poly-dimethyl siloxane with ethylene oxide and hydroxy affinic groups
- Byk®P104 a solution of low molecular weight unsaturated polycarboxylic acid polymers
- Byk®9076 an alkylammonium salt of a high molecular weight copolymer
- Byk®9077 high molecular weight polymer with secondary and tertiary amine affinic groups; Anti-Terra®202 - a solution of an alkylammonium salt of a polycarboxylic acid, electro-neutral; Anti-Terra®204 - a solution of a carboxylic acid salt of polyamine amides, electro-neutral; Anti-Terra®U- a solution of a salt of unsaturated polyamine amides and lower molecular weight polymers, electro-neutral.
- Disperbyk®163, Disperbyk®-107, Disperbyk®-108, BYK®-345, BYK®-9077, and BYK®-9076 are preferred. Disperbyk® 163 is especially preferred.
- the amount of CNTs used is generally 0.001-2 wt%, more preferably 0.01-0.7 wt% of the mixture comprising CNT, dispersion aid and solvent.
- the amount of dispersion aid used is generally at least about 10% (based on weight) of the amount of CNT used, preferably at least 100% (based on weight) of the amount of CNT used. More preferably, an excess of dispersion aid (i.e., >100%, based on weight) is used.
- the ratio of PANI or PANI-DNNSA to CNTs in the dispersion mixture is generally from about 5:1 to about 200:1 (by weight).
- the sonication process steps can be carried out using a sonic probe or sonic bath/probe combination.
- the mixtures are placed in a thermostatically controlled bath. Suitable bath temperatures are from 0 0 C to about 80 0 C, preferably from about 2O 0 C to about 50°C. Sufficient dispersion is usually achieved in each step in 10-20 minutes.
- the sonication steps can be interrupted periodically to scrape or rinse down the walls of the reaction vessel to return to the mixture any CNTs or other solids that have been splashed or sprayed onto the vessel walls.
- the mixture of carbon nanotubes, first solvent and dispersion aid be sonicated for 10-20 minutes.
- the resulting mixture is typically sonicated for an additional 1-20 minutes.
- An optional filtration step can also be carried out after either the first or second sonication step to remove undispersed CNT agglomerates and/or other particulate materials.
- such a filtration is carried out using a filter comprising a woven metal or polymer mesh.
- filters with high mesh counts i.e., small pore sizes
- Mesh counts or greater than 400 x 400 are especially preferred.
- the metal or polymer mesh can be any material that is non-reactive with the components of the dispersion, including but not limited to stainless steel, polyester, nylon, and PEEK (polyetheretherketone). Suitable filters are available from Sefar America Inc., Kansas City, MO. The effectiveness of the dispersion can be tested by coating the dispersion onto a suitable substrate, removing the solvent, and imaging the coated substrate by optical or other imaging techniques. SEM is particularly useful in this regard.
- the carbon nanotubes (MGP/HiPco R0236) used in these examples were obtained from Carbon Nanotechnologies, Inc. (Houston, TX) and used as received.
- the dispersion aid, Disperbyk®-163, was obtained from BYK Chemie USA (Wallingford, CT) and used as received.
- the solution of PANI-DNNSA was prepared by an emulsion process, as described in Macromolecules, 1998, 31 , 1735-44. The glass slides were cleaned before use with isopropanol. The CNT/PANI-DNNSA solutions were blade-coated onto the glass slides with a 50 micron gap to give a final (dried) coating thickness of about 1-4 micron.
- PANI-DNNSA (7.1050 g, 27.30% solids in a mixture of 2-butoxyethanol and xylenes, 1 :4 weight ratio) was added to the dispersed carbon nanotubes and then the bottle was put in a water bath at 45°C for 5 minutes to allow temperature equilibration. The mixture was dispersed with probe sonication for 5 minutes, during which time the mix was stirred gently with a spatula at 1 -minute intervals.
- a mixture of CNTs and PANI-DNNSA was prepared as above, except that no dispersion aid was used.
- a coated substrate was prepared as in Example 1. An SEM image of the coated substrate is shown in Figure 2.
- the size and number of defects in the coated substrate is clearly greater in the sample prepared without a dispersion aid.
