In the office, Xu Chuan got the full report on this electrochemical synthesis of graphene.

From the complete synthesis process to the final synthesis of graphene, the test reports and index parameters are complete.

After briefly flipping through the synthesis process, his eyes fell on the graphene test report and index parameters.

[Graphene powder A (colloidally disperseable), number of layers: 1–5 layers (controllable), average thickness: 2nm, graphene sheet size: 5–50μm (controllable), purity (carbon content): about 97wt%]

[Graphene powder B (lower cost), number of layers: 2–10 layers (controllable), graphene sheet size: 20–200μm (controllable), specific surface area: about 50 m2/g, purity (carbon content): about 98wt%]

【Graphite Film A】

The data of one item and the indicator parameters obtained from the test passed through Xu Chuan's eyes.

Graphene products are generally divided into two forms: graphene powder and graphene film.

At present, graphene powder is mainly used in new energy, anti-corrosion coatings, composite materials, biosensors and other fields, with a wide range of applications.

Graphene films are mainly used in flexible displays, sensors, electronic devices and other fields, and the application range is relatively small.

But his main focus fell on graphene films.

Because compared with graphene powder, graphene film has a broader prospect.

Whether it's flexible displays, sensors, or graphene electronics, they're all finer and more expensive.

Moreover, it is particularly difficult to produce high-quality graphene in a large area, and the market that can be created is even larger.

[Graphite film A: density: 0.3–2.2 g/ml (adjustable), transmittance: 99.98-99.7% (number of layers): thickness: 1-50μm (adjustable), thermal conductivity: 4837.21 W/mK, conductivity: 10^6, tensile strength: 1 - 50 MPa, internal carrier mobility: 2×10^5cm^2/vs]

【Graphite Film B:.】

According to the data of the six groups of controlled test experiments, the graphene film prepared by electrochemical method is quite excellent in various parameters and indicators.

Whether it is light transmittance, thermal conductivity, or electrical conductivity and tensile strength, it can be said to be the top level in graphene films.

This level of graphene film has a relatively wide range of applications.

For example, heat dissipation in mobile phones or computers.

Nowadays, after the great leap forward in mobile phone performance, there is actually no shortage of performance, but the release performance of mobile phones needs to be heated, and the stronger the performance of the SoC, the higher the heat.

However, the internal design of mobile phones is expensive, and "how to conduct heat" in the process of releasing the performance of mobile phones is the key to solving the problem of smart phones.

With a thermal conductivity of up to 4837.21 W/mK and a thermal conductivity of nearly 5,000, its thermal conductivity exceeds that of all thermal conductive materials on the market.

In general, mobile phones or computers use thermal grease or thermal silicone sheets to dissipate heat.

The thermal conductivity of these two materials is only about 10W/mK, even if it is a high thermal conductivity silica gel, it is only about 15-45W/mK.

The better mobile phone uses a more advanced and expensive thermal conductive solution composed of several thermal conductive materials, such as phase change thermal conductive sheet, thermal conductive graphite sheet, VC vapor chamber, and thermal conductive silicone gel.

But even if it is the graphite sheet with the best thermal conductivity, its thermal conductivity is only 1500-2000w/

This number is exaggerated enough in conventional heat dissipation materials, but compared with graphene, which is as high as nearly 5,000, the performance is very stretched.

I have to say that the results of the Chuanhai Materials Laboratory this time, even without him, are enough to make this research institute one of the top materials research institutes in the world.

After all, this is a technology that can industrialize and mass-produce high-quality graphene materials.

At the celebration party in the evening, Xu Chuan naturally participated in it together.

After all, for the Chuanhai Materials Research Institute, the ownership of the results developed by the researchers under its name belongs to the research institute.

The graphene technology researched by Yan Liu and the researchers, whether it is a patent or something else, basically belongs to the research institute and laboratory.

These are industry practices in the materials industry, and they will also be stipulated in the contract, and there is nothing to dispute.

As for the researchers who make the results, they generally get a project grant and one or more papers written in the course of the research.

Of course, in many cases, after the researcher has made the results, considering the project confidentiality, patents, other related projects, etc., the paper may be in his own hands, and the paper may be postponed for a period of time before being released and made public.

Or sometimes it is even impossible to disclose or even apply for a patent.

In this case, the institute or laboratory will naturally compensate the researcher for something else.

Just like this time, after considering the particularity of high-quality graphene, Xu Chuan chatted with Yan Liu, and there is a high probability that the paper may have to be postponed or not sent at all.

But the compensation is handsome.

To put it simply, in addition to a promotion and salary increase and an additional bonus, Yan Liu can obtain two percent of the net income after the mass production of graphene is scaled up.

Don't look at the small number of two percent, but the market for high-quality graphene is quite broad, almost billions of meters of gold every year.

Although it is impossible for Chuanhai Materials Research Institute to monopolize all the markets, with the outflow of high-quality graphene, this market will gradually expand over the years.

In the future, the market for high-quality graphene may not be billions, but tens of billions or even hundreds of billions.

Even if the Chuanhai Materials Research Institute can only occupy half or even one-third of the market, the dividends that Yan Liu can share are calculated in tens of millions or billions.

In fact, for most research institutes, under normal circumstances, it is difficult for ordinary researchers to get a share even if they develop a certain material or patent that can bring high profits to the research institute by chance.

After all, you are doing research with the funds of the institute, using the equipment of the institute, and the contract also stipulates the ownership of these things.

However, for Xu Chuan, he has always been more generous in this regard.

And it is definitely worth it to bind Yan Liu to the Chuanhai Materials Research Institute with two percent of the profits, so as to prevent other research institutes from poaching and leaking the synthesis process and method of graphene.

Of course, this also has the effect of buying horse bones.

When other researchers find out, they will definitely work hard to do scientific research.

And for every achievement, even if a part of the profits are given to the researchers, the institute still makes a lot of money.

It's totally worth it.

As for this compensation, Yan Liu naturally accepted it happily.

Although the paper can't be sent, the promotion and salary increase bonuses are all available that I didn't even think of.

If it weren't for this cheekiness, he really wanted to shout: 'The god of Sichuan is awesome! Kawajin atmosphere! ’

After all, scientific researchers work hard to do experiments and publish papers, isn't it just to improve their fame and earn more money for promotions and raises?

Although there are ideals, before chasing ideals, you have to take care of your own bread, don't you?

This time, it was directly in one step, and there were unexpected dividends, and he was not satisfied, so it really couldn't be said.

After briefly dealing with the work brought about by the mass production of graphene, Xu Chuan found the master Xiong Fan Pengyue and handed him a USB flash drive.

"This is the result of a study of a strongly correlated electronic system, mainly for the strong diamagnetic mechanism of KL-66 material that was previously studied in South Korea."

"You find a few modelers who are definitely 'clean', and use it to build a targeted mathematical model that is reflected in the high-temperature copper-carbon-silver composite superconducting material system."

"It's an important job, and it's important to keep it confidential."

Xu Chuan handed over the USB flash drive in his hand, which contained his research results some time ago.

Although the problem of strongly correlated electronic system is still stuck in the last step, the mechanism of strong diamagnetic resistance of KL-66 material has been completed.

The rest of the work is to use this research to build a mathematical model, and then introduce high-temperature copper-carbon-silver composite superconducting materials to see if the critical magnetic field of superconducting materials can be improved on the original basis.

In KL-66 material, the strong diamagnetic mechanism is derived from the substitution of copper for ions in the lead phosphate insulation network, and the stress is transferred to the Pb of the cylinder at the same time, resulting in the deformation of the cylindrical interface, resulting in the formation of magnetic traps.

Mathematically, the two branches of electrons in the Fermi arc state connect the c-axis to break the inverted symmetry, which in turn causes the Dirac cone to split into two Weyl nodes with opposite chirality, resulting in non-trivial quantum phenomena.

If you can't understand this, in the simplest terms, you put a massive star in the solar system, replacing planets like Jupiter or Saturn.

And because of the star's strong gravitational pull, the new star will stretch space-time and form another gravitational field, changing the trajectory of other celestial bodies in the solar system.

The magnetic trap in KL-66 material has a similar effect, it forms its own unique additional magnetic moment, and the direction of the magnetic moment is opposite to the direction of the external magnetic field, forming the Ramor precession phenomenon, which has strong diamagnetism.

Theoretically, this phenomenon is applicable to many materials, especially semi-metallic and semi-organic bonded materials.

However, how to control the atomic unit to form a unique additional magnetic moment is a difficult problem.

This needs to be continuously experimented and deduced in the future.

But at least, before he could conduct the experiments himself, the relevant mathematical calculation models had to be made.

I have to say that if we make another breakthrough in the critical magnetic field of superconducting materials, we will be able to make miniaturized and controllable nuclear fusion and aerospace engines, which will really give South Korea a big credit.

If it weren't for the KL-66 material they came up with, it would be as difficult as climbing to the sky if they wanted to improve the critical magnetic field of the superconducting material.

Although the purpose for which they came up with this material may not exist, the value in it is real.

Even, its own scientists, did not find out.

PS: Second watch, ask for a monthly pass, there is another chapter in the evening!
