Description

Dispersion method of Carbon nano sheet

The present invention relates to a dispersion technique for dispersing graphene or graphene oxide chemically and physically, and then dispersing the solvent, binder, surfactant, and dispersant into a very stable solution.

Allotropes of carbon can be divided into diamonds with covalent bonds (sp3 bonds) and graphites with pie bonds, depending on the form of bonds between carbons, and fullerenes, carbon nanotubes (CNTs), and graphenes, depending on the three-dimensional structure Can be broken down into pins.

Graphene (GP) is generally manufactured through vapor deposition (CVD) and chemical carbon layer stripping (Mater. Today 10, 2026 (2007)). Graphene (GP) refers to a material in which a single layer of graphite is completely isolated, but even in a carbon layer of 10 to 20 layers or less (10 to 20 nm or less), the physical properties inherent to quantum mechanical graphene (GP) are included. It is also used as a concept. Their structure is based on a planar honeycomb with sp ² bonds, of which three of the four sp-bonded electrons are used, and one of the remaining electrons is in the form of a pie bond on the top and bottom of the two-dimensional plane, and conducts electricity. It may be formed into a structure that plays an important role in physical properties. Theoretical findings indicate that the electrons on the graphene surface are ballistic conduction and move in any length. The allowable current density is 109 A / cm ^2, which is about 1,000 times that of copper. Graphene's high conductivity properties are similar to those of metallic carbon nanotubes (CNTs). Materials with small diameters are called quantum dots, quantum wires, and quantum plates. In particular, the meaning of thickness is emphasized in quantum plates, and the movement of electrons in the quantum plates is confined to the two-dimensional plane, and the movement in the thickness direction is the diameter of Dvorpa. Smaller, the movement is extremely limited.

Graphene oxide (GO) refers to a state in which the carbon surface layer is oxidized, such as COOH, CHO, C = O, C-OH, SO ₃ H, phosphoric acid, and is dissolved in an aqueous solution. Although the purity of graphene oxide (GO) is low, various methods of oxidizing graphite have been known. In 1859 Bodie oxidized graphite powder using KCl and nitrate vapors (Phil. Trans. 149, 249 (1859)). Since then, various acids have been applied as a medium for oxidizing graphite. Representatives Hofman and Frenzel (Ber. 53B, 1248 (1930)) and Hamdi (Kolloid Beihefte, 54, 554 (1943)) developed a method of mixing concentrated sulfuric acid and 63% nitric acid with graphite powder and slowly adding KCl solution. It was. In the 1980s, Hummers maximized graphite oxidation rates using concentrated sulfuric acid, NaNO3, and KMnO4.

However, commercialization of graphene and graphene oxide has been delayed because highly dispersed and complexed technologies have not been developed as an application technology of graphene and graphene oxide prepared through conventional chemical and physical methods. On the other hand, carbon nanotubes, which are other carbon nanomaterials, have been actively developed for about 10 years, and many application technologies such as transparent conductive films, solar cell electrodes, and high-conductivity conductive pastes have been developed.

An object of the present invention is to highly disperse graphene or graphene oxide using a chemical dispersion method and a mixing method such as carbon nanotubes, and to use it for thin film coating.

Solvent freedom must first be ensured for various coating dispersions, and various dispersion solvents are disclosed herein.

When graphene oxide (GO) or graphene (GP) enters into the dispersion solvent, binders and surfactants are required as much as aggregation and precipitation occur (particularly crumpled differently from carbon nanotubes). Specific binders and surfactants are disclosed herein.

In other systems (carbon nanotubes), as a key feature of the present invention, the surfactant or binder alone shows excellent physical properties. However, graphene and graphene oxide are dispersed even in solution because of their two-dimensional shape. Crumpled badly. In other words, the dispersed state of the wrinkled state and the dispersed state of the unfolded state are possible. In the present invention, it was intended to prepare a dispersion solution in the unfolded state in the solution phase. To this end, three solvents, a surfactant, and a binder must always be in. The dispersion in which one is missing becomes a crumpled dispersion. Two-dimensional graphene or graphene oxide has inherent physical properties, and when present alone in a vacuum or in a solvent, it tries to go in a crumpled form by the law of increasing entropy. The crumpled form is thermodynamically more stable than the flat form with increased entropy and reduced entropy. From a molecular structural point of view, very thin plates are folded by small external forces, and mutual bonding occurs at the folded parts. This phenomenon of bonding and folding comes from a tendency to be thermodynamically stable. In other words, two-dimensional, very thin plates are thermodynamically unstable, so they try to stabilize anyway, which is best suited for crumpled shapes. If thermodynamically unstable, to maintain them in some stretched state, they must be accompanied by external force. It is the surfactant and the polymer binder which give the forcing force. They penetrate properly between two-dimensional flat graphenes to prevent the graphenes from clumping together while preventing their own wrinkles. However, in order to prevent the strong folding, only one binder or a surfactant is very difficult and a solvent suitable for the surfactant / binder must be selected.

In the present invention, graphene oxide (GP) and graphene (GO) are collectively referred to as "carbon nano plate". The present invention comprises the steps of preparing a graphene-dispersed solvent composition by adding a dispersion solvent in a ratio of 50 to 10,000,000 weight with respect to 100 weight of carbon nanoplatelets; (b) adding a polymer binder to the carbon nanoplatelet-dispersed solvent composition at a ratio of 1 to 50,000 weight based on 100 weights of carbon nanoplatelet to prepare a carbon nanoplatelet-dispersed solvent-binder composition; And (c) adding a surfactant to the carbon nanoplatelet-dispersed solvent-binder composition in a ratio of 0.01 to 100 wt% based on 100 wt% of carbon nanoplate; It provides a carbon nano plate dispersion method comprising a.

According to the present invention, it is possible to obtain a dispersion in which graphene oxide (GO) and graphene (GP) are uniformly dispersed without being folded.
