The Introduction of Dispersible graphene

Dispersible graphene is prepared through the complete reduction of graphene oxide, which is prepared by the modified Hummer’s method. It should be noted that the graphene prepared by the usual method is easy to form the graphene aggregation. It is very hard, even its volume is much smaller than its parent material graphite. The resulting graphene agglomerate is not soluble or redispersable in water or other polar solvents, making further processing difficult. Our product Dispersible graphene overcome the challenge, and it can be redispersed in many solvents, such as in water, alcohol, acetone, DMF etc. It should be noted that the product we supply is the single-layer (>80%) dispersible graphene, not graphene nanoplate.Water-dispersible graphene was prepared by reacting graphite oxide and 6-amino-4-hydroxy-2-naphthalenesulfonic acid (ANS). X-ray diffraction study showed that the basal reflection (002) peak of graphite oxide was absent in the ANS-functionalized graphene (ANS-G), indicating crystal layer delamination. Ultraviolet-visible spectral data were recorded to assess the solubility of the ANS-G in water. Fourier transform infrared spectral analysis suggested the attachment of ANS molecules to the surface of graphene. Raman and x-ray photoelectron spectroscopy revealed that oxygen functionality in the graphite oxide had been removed during reduction. Atomic force microscopy found that the thickness of ANS-G in water was about 1.8 nm, much higher than that of single layer graphene. Thermal stability measurements also indicated successful removal of oxygen functionality from the graphite oxide and the attachment of thermally unstable ANS to the graphene surfaces. Dispersible graphene is prepared through the complete reduction of graphene oxide, which is prepared by the modified Hummer's method. It should be noted that the graphene prepared by the usual method is easy to form the graphene aggregation. It is very hard, even its volume is much smaller than its parent material graphite.
The electrical conductivity of ANS-G, determined by a four-point probe, was 145 S m(-1) at room temperature. The thickness of graphene nanoplate is alway larger than 20 nm, therefore it always consists of more than 50 layer graphene, and it lose the intrinsic special properties of single-layer graphene. The resulting graphene agglomerate is not soluble or redispersable in water or other polar solvents, making further processing difficult. Our product Dispersible graphene overcome the challenge, and it can be redispersed in many solvents, such as in water , Alcohol, acetone, DMF etc. Fig.1 shows the difference between dispersible graphene and non-redispersible graphene.

The Use of carboxylated carbon nanotubes

The carboxylated carbon nanotubes acid rate (Carboxyl ratio) : 2.31 wt % (The rate of surface carbon atom: 8-14 mol %) water-soluble carbon nanotubes performance: but even immiscible in inorganic powder materials.

USES: preparing inorganic conductive or inorganic reinforced materials. Preparation of polymer conductive or polymer reinforced composites. Oil-soluble carbon nanotubes: performance: but even immiscible in polymer materials. CAS number: 308068-56-

semiconductor and metallic carbon nanotubes under transverse electrical fields are investigated through density functional theory based on first-principles calculations. The external field polarizes the system, resulting in an induced electric dipole moment toward the incident field with the modulus directly dependent on the field strength. The structural and electronic properties of the resulting system due to the orbital hybridization between the nanotube and COOH states are shown to be affected by the applied field. These results open new perspectives for different potential uses, such as to enhance the capacity of the composite to bind and characterize other substances, especially polar molecules, and as mechanisms to monitor the bound substances or control electron injection or detection, by varying the external field through a controlled application.

To enhance its pseudocapacitance, ruthenium oxide must be formed with a hydrated amorphous and porous structure and a small size, because this structure provides a large surface area and forms conduction paths for protons to easily access even the inner part of the RuO2. In this study, we report that highly dispersed RuO2 nanoparticles could be obtained on carboxylated carbon nanotubes. This could be achieved by preventing agglomeration among RuO2 nanoparticles by bond formation between the RuO2 and the surface carboxyl groups of the carbon nanotubes. Highly dispersed RuO2 nanoparticles on carbon nanotubes showed an increased capacitance, which can be explained by the fact that with the decrease in size protons were able to access the inner part of RuO2, so that its utilization was increased. The high dispersion of RuO2 is therefore a key factor to increase the capacitance of nanocomposite electrode materials for supercapacitors.

The Introduction of carbon nanotube dispersion

The carbon nanotube dispersion in various media and methods of using the same in such applications as inks, coatings, and composites and in various electrical and electronic articles are disclosed. A dispersant is used which has the formula P-(U-Y)s where P is a metal or metal-free phthalocyanine, Y is a compatibilizing moiety with a molecular weight between 500 and 5000 g/mol, U is a linking moiety covalently bonding Y to P, and s is an integer between 1 and 4.
Carbon Nanotubes have shown great promise as an economical alternative to making transparent conductive oxide (TCO) layers, commonly used with organic and dye-sensitized cells, as well as several other electronics applications. Sono-Tek's ability to spray carbon nanotubes makes R&D processes ideal for using ultrasonic nozzle technology. The ability to create efficient transparent conductive films with CNTs at low temperatures allows the possibility to greatly reduce manufacturing costs of the TCO layer.
(FR)L’invention concerne la dispersion efficace de nanotubes de carbone dans divers milieux et des procédés les utilisant dans des applications telles que les encres, les revêtements et les composites et dans divers articles électriques et électroniques. On utilise un dispersant de formule P-(U-Y)s, où P est une phtalocyanine contenant ou non un métal, Y est un fragment de compatibilisation possédant un poids moléculaire situé entre 500 g/mol et 5000 g/mol, U est un fragment de liaison liant par liaison covalente Y à P, et s est un nombre entier entre 1 et 4.
Parallel alignment of nanotubes can be obtained by dispersion in a self-organizing anisotropic fluid such as a nematic liquid crystal. Exploiting the cooperative reorientation of liquid crystals, the overall direction of the nanotube alignment can be controlled both statically and dynamically by the application of external fields. These can be electric, magnetic, mechanic, or even optic in nature. Employing multiwall as well as single-wall carbon nanotubes, we show their parallel alignment along a uniform liquid crystal director field and electrically verify their reorientation behavior for two complementary geometries. These demonstrate electrically controlled carbon nanotube OFF–ON and ON–OFF switches. Further applicational potential will be outlined.
Functionalization
Pristine nanotubes are unfortunately insoluble in many liquids such as water, polymer resins, and most solvents.  Thus they are difficult to evenly disperse in a liquid matrix such as epoxies and other polymers. This complicates efforts to utilize the nanotubes’ outstanding physical properties in the manufacture of composite materials, as well as in other practical applications which require preparation of uniform mixtures of CNTs with many different organic, inorganic, and polymeric materials.
To make nanotubes more easily dispersible in liquids, it is necessary to physically or chemically attach certain molecules, or functional groups, to their smooth sidewalls without significantly changing the nanotubes’ desirable properties. This process is called functionalization. The production of robust composite materials requires strong covalent chemical bonding between the filler particles and the polymer matrix, rather than the much weaker van der Waals physical bonds which occur if the CNTs are not properly functionalized.
