- the invention focuses on a crystal structure of graphite, and, at first, matters relating to the crystal structure will be explained. It has been known that natural graphite is classified into three types of crystal structures, namely hexagonal crystals, rhombohedral crystals and disordered crystals, depending on an overlapping manner of layers. As shown in FIG. 1 , hexagonal crystals have a crystal structure in which layers are arranged in the order of ABABAB . . . , while rhombohedral crystals have a crystal structure in which layers are arranged in the order of ABCABCABC . . .
- Non-Patent Literatures 1 and 2 In natural graphite, there are almost no rhombohedral crystals in a stage where natural graphite is excavated. However, about 14% of rhombohedral crystals exist in general natural graphite-based carbon materials because pulverization or the like is carried out in a purification stage. In addition, it has been known that a proportion of rhombohedral crystals converges on about 30% even when pulverization is carried out during purification for a long time (Non-Patent Literatures 1 and 2).
- Non-Patent Literature 3 a proportion of rhombohedral crystals is about 25% (Non-Patent Literature 3). Furthermore, the proportion is up to about 30% even when heat of an extremely high temperature of 3000° C. is applied thereto (Non-Patent Literature 2).
- the upper limit is about 30%.
- An energy required for the exfoliation is inversely proportional to the cube of the thickness. Therefore, in a thick state where numerous layers are overlapped, graphene is exfoliated by a weak physical force such as by very feeble ultrasonic waves.
- a very large energy is required. In other words, even if graphite is treated for a long time, only weak parts of the surface are exfoliated, and large parts remain not exfoliated.
- the present inventors succeeded in increasing a proportion of rhombohedral crystals (3R), which had been increased to only about 30% by treatments of pulverization or heating to an extremely high temperature, to 30% or more by carrying out predetermined treatments, as shown below, to natural graphite.
- the following findings were obtained as results of experiments and studies. That is, when a content of rhombohedral crystals (3R) in a graphite-based carbon material is higher, particularly when the content is 31% or more, there is a tendency that graphene is easily exfoliated by use of such a graphite-based carbon material as a precursor, thereby easily obtaining a highly concentrated and dispersed graphene dispersion or the like.
- a graphite-based carbon material from which graphene is easily exfoliated by carrying out predetermined treatments to natural graphite, and which makes it possible to disperse graphene at a high concentration or to a high degree, is called a graphene precursor.
- a method of producing a graphene precursor showing predetermined treatments, a crystal structure of the graphene precursor, and a graphene dispersion using the graphene precursor will be described in that order in examples below.

- Sample 5 produced by the production apparatus B which applies a treatment with a ball mill and a microwave treatment, had high rates of peak intensities P3 and P1, and a Rate (3R) defined by Equation 1 showing a rate of P3 to a sum of P3 and P4 was 46%.

- the intensity ratio P1/P2 was 0.014.

- TEM transmission electron microscope
- the grid coated with the diluted supernatant was used for Sample 1.
- the size corresponds to a maximum length L of a flake 33 , which was 600 nm, based on FIG. 10( a ) .
- the number of layers the end face of the flake 33 was observed in FIG.
- a particle size distribution (distribution of sizes) of thin flakes included in the graphene dispersion of Sample 5 (Rate (R3) of 46%) produced by the production apparatus B of Example 1 was a distribution having a peak of 0.5 ⁇ m.
- a distribution which had a peak in 3 layers and in which graphene having 10 layers or less were 68% was observed.

- a distribution in which those having 30 layers or more occupied the greater portion and in which graphene having 10 layers or less were 10% was observed.
- Samples 1, 5 and 6 in FIG. 13 are those described above.
- Samples 2, 3 and 4 were produced by the production apparatus B which carried out a treatment based on a ball mill and a microwave treatment, and were graphene dispersions produced using graphene precursors which had been produced by making the irradiating time of microwaves shorter than that for Sample 5.
- Sample 7 was produced by the production apparatus A which carried out a treatment based on a jet mill and a plasma treatment, and was a graphene dispersion produced by using a graphene precursor which had been produced by applying plasma of a higher output than that for Sample 6.
- the Rate (3R) is preferably 40% or more from a view point that the proportion of dispersed graphene of 10 layers or less sharply increases to 50% or more.
- an upper limit for the Rate (3R) is considered that the upper limit is not particularly defined. However, it is preferable that the upper limit is defined such that the intensity ratio P1/P2 simultaneously satisfies 0.01 or more, because graphene precursors are easily exfoliated when a dispersion or the like is produced. In addition, in cases of production methods using production apparatuses A and B, the upper limit is about 70%, from a viewpoint that graphene is easily produced. Also, a method combining a treatment based on the jet mill of the production apparatus A and a plasma treatment is more preferable, because a graphene precursor having a higher Rate (3R) can easily be obtained. Additionally, the Rate (3R) as long as it reaches 31% or more by combining the physical-force-based treatment and the radiowave-force-based treatment.
- Example 1 a case where the ultrasonic treatment and the microwave treatment were combined for obtaining a graphene dispersion is explained.

- Example 3 an example used for a conductive ink will be described.
- Example 4 an example in which a graphene precursor was kneaded with a resin will be explained.

- Zinc stearate is explained above as an example of the dispersing agent. However, those suited for compounds may be selected. As examples of the dispersing agent, anionic (anion) surfactants, cationic (cation) surfactants, zwitterionic surfactants, and nonionic surfactants can be mentioned. In particular, anion surfactants and nonionic surfactants are preferable for graphene. Nonionic surfactants are more preferable.
- nonionic surfactants are surfactants which do not dissociate into ions and which show hydrophilic properties by hydrogen bonds with water, as observed in oxyethylene groups, hydroxyl groups, carbohydrate chains such as glucoside, and the like, there is a merit that they can be used in nonpolar solvents, although they do not have a strength of hydrophilicity as high as ionic surfactants. Further, this is because, by varying chain lengths of their hydrophilic groups, their properties can freely be changed from lipophilic properties to hydrophilic properties.
- anionic surfactants X acid salts (as for the X acid, for example, cholic acid, and deoxycholic acid), for example, SDC: sodium deoxycholate, and phosphate esters, are preferable.
- nonionic surfactants glycerol fatty acid esters, sorbitan fatty acid esters, fatty alcohol ethoxylates, polyoxyethylene alkyl phenyl ether, alkyl glycosides, and the like are preferable.
- the production apparatus A using a jet mill and plasma, and the production apparatus B using a ball mill and microwaves are described as production apparatuses which produce a graphene precursor.
- a treatment based on a radiowave force such as by microwaves, millimeter waves, plasma, electromagnetic induction heating (IH), and magnetic fields
- a treatment based on a physical force such as by a ball mill, a jet mill, centrifugal force, and supercriticality
- a precursor having a high Rate (R3) can be obtained. Therefore, such combination of the treatments is preferable.
- any specific treatments for the physical-force-based treatment and the radiowave-force-based treatment can be adopted.
- effects based on a radiowave force and a physical force are simultaneously directed thereto.
- a radiowave force and a physical force may alternately be directed thereto at predetermined intervals.

- the pellets produced in (2) were formed into a test piece according to JIS K7161 1A (length: 165 mm, width: 20 mm, thickness: 4 mm) by an injection molding machine.
- the elastic modulus (Mpa) of the test piece produced in (3) was measured under a condition of a test speed of 500 mm/min according to JIS K7161 by a table-top type precision universal tester produced by Shimadzu Corporation (AUTOGRAPH AGS-J).
- the kneading conditions were as follows.
- Pressurization in furnace applying 0.3 MPa for 10 minutes after start, and depressurizing to atmospheric pressure after the 10 minutes elapsed
- the dispersion of the above-described graphene dispersion into a resin is considered as follows.
- the melting point of a resin is generally 100° C. or higher, water evaporates in atmosphere, but in a pressing-type kneader, the inside of a furnace can be pressurized. In the inside of the furnace, the boiling point of water is raised so that the dispersion is kept in a liquid form, whereby an emulsion of the dispersion and the resin can be obtained.
- the inside After applying pressure for a predetermined time, the inside is gradually depressurized, which causes the boiling point of water to decrease, thereby allowing water to evaporate.
- graphene confined in water are left in the resin. This causes graphene and graphite-based carbon materials to be dispersed at a high concentration in the resin.
- the graphene dispersion is kneaded into the resin preferably immediately after the graphene dispersion is obtained.
- the following may be used as the means for obtaining the emulsion of the dispersion and the resin, other than the pressing kneader: a chemical thruster; a vortex mixer; a homomixer; a high-pressure homogenizer; a hydroshear; a flow jet mixer; a wet jet mill; and an ultrasonic generator.
- IPA 2-propanol
- NMP N-methylpyrrolidone
- DMF N,N-dimethyl formamide
- Table 4 illustrates the relationship between the Rates (3R) of around 30% and the elastic moduli of resin molded articles. It should be noted that Sample 00 in Table 4 is a blank Sample in which no precursor was kneaded, Samples 11 and 12 have Rates (3R) between that of Sample 1 and that of Sample 2, and Sample 21 has a Rate (3R) between that of Sample 2 and that of Sample 3.
