"I think this technology alone can completely break the world."

Chen Fan looked at the files in Cao Yuan's hands and said: "It's an expanded technology, but the cost has never come down."

Cao Yuan said: ‘If the separation of graphene is successful, it will inevitably represent the progress of various technologies. ’

Chen Fan thought about it, and began to organize the data in his head.

Chemical data and physical data are different, and the structure of the laboratory is also different. The chemical laboratory is more of equipment.

Or some dangerous substances.

You never know whether this laboratory produces the fruit of God or the dinner of the devil.

And these, Chen Jiaqian has taught Chen.

"Perhaps, your moonlight is the core?"

"I keep the cost of Moonlight within 30 million at most. If it is lower, it will be impossible."

"This is enough. To know a core technology machine, tens of millions is a very common thing."

Cao Yuan found another document and handed it to Chen Fan.

Chen Fan read.

"Redox method is to oxidize natural graphite by using chemical reagents such as sulfuric acid, nitric acid, potassium permanganate, hydrogen peroxide and other oxidizing agents to increase the spacing between graphite layers, and insert oxides between graphite layers to obtain oxidation. Graphite (GraphiteOxide). Then the reactants are washed with water, and the washed solid is dried at low temperature to obtain graphite oxide powder. The graphite oxide powder is peeled off by physical peeling, high temperature expansion and other methods to obtain graphite oxide In the end, graphene oxide is reduced by chemical methods to obtain graphene (RGO). This method is simple to operate and has high yield, but the product quality is low. The redox method uses strong acids such as sulfuric acid and nitric acid, which poses a greater risk , But also need to use a lot of water for 03 cleaning, which brings great environmental pollution.

Graphene prepared by redox method contains abundant oxygen-containing functional groups and is easy to modify. However, it is difficult to control the oxygen content of the reduced graphene when the graphene oxide is reduced. At the same time, the graphene oxide will be continuously reduced under the influence of the sun and the high temperature in the carriage during transportation. Therefore, the oxidation-reduction method The quality of graphene produced is often inconsistent from batch to batch, and it is difficult to control the quality"

"Is this the latest method?"

"No, this is the method that was abandoned six years ago, do you think, where is the modification?"

"Environmental problems such as sulfuric acid and nitric acid, I think, this can also be solved, but this is not what I want."

Cao Yuan sighed helplessly. This is the gap, the gap between genius and genius. This experiment lasted for six years. After Chen Fan learned about it, he decisively gave a new way to deal with it.

Chen Fan wrote a chemical equation.

CH3Cl+Cl2→CH2Cl2+HCl

Cao Yuan said, "Is it methane?"

"No, I am revising, wait for me."

After Chen Fan modified it, he continued to write and add to it. In fact, this is the most common balancing method in chemistry.

Students in the third year of junior high school are good.

And this kind of balancing method, if it is creative, then it is difficult.

Soon, Chen Fan wrote a very long formula and began to experiment.

In the afternoon, after Cao Yuan got the data, his face unconsciously smiled.

"Do you think this is not enough?"

"Not enough, the cost is still high. Although the environmental issues have been dealt with, but what materials are needed? The money required is really too much, and I don't think it is suitable."

"You have been controlled within 20 million."

"Twenty million to make a mobile phone is itself an unrealistic thing. There is no way for civilian use. Then this research needs to be completely invalidated."

Chen Fan casually ripped everything apart and threw it into the sky.

Cao Yuan looked at his younger brother helplessly. In fact, he had experienced these things a few years earlier.

This is nothing. Chemistry is very tormenting, but also very attractive. Chen Jiaqian's body is so broken, but she still works hard in chemistry experiments. If someone specializes and prevents all of this, then everything is impossible. Estimated things.

Cao Yuan left the laboratory and left some information.

Chen Fan searched for information one by one.

"The epitaxial method uses the atomic structure of the growth substrate to "plant" graphene. First, carbon atoms are infiltrated into ruthenium at 1150°C, and then cooled. After cooling to 850°C, a large number of carbon atoms previously absorbed will float on the surface of the ruthenium. , The single layer of carbon atoms in the final lens shape will grow into a complete layer of graphene. After the first layer is covered, the second layer begins to grow. The underlying graphene will interact strongly with ruthenium, and after the second layer It is almost completely separated from the ruthenium, leaving only weak electrical coupling. However, the graphene sheets produced by this method are often uneven in thickness, and the adhesion between the graphene and the matrix will affect the characteristics of the carbon layer."

This still doesn't work, but it can be handled, and the cost is still too high. The minimum is 40 million to make a part, which is completely nonsense.

Not enough, or not enough.

Chen Fan looked at the bottom part of the information, which was from Hemo's method.

This great chemist tried to make graphene in a new way.

"Prepare graphite oxide by the Hummer method; put the graphite oxide in water for ultrasonic dispersion to form a uniformly dispersed graphene oxide solution with a mass concentration of 0.25 g/L to 1 g/L, and then add dropwise to the graphene oxide solution Ammonia water with a mass concentration of 28%; dissolve the reducing agent in water to form an aqueous solution with a mass concentration of 0.25g/L～2g/L; mix the prepared graphene oxide solution and the reducing agent aqueous solution evenly, and place the resulting mixed solution in Stir in an oil bath. After the reaction is complete, the mixture is filtered, washed, and dried to obtain graphene."

Chen Fan looked at the information, and what was conveyed in his eyes was the preparation of various reagents. These were not enough, or not enough.

Rough calculations, the cost of these needs may be 15 million.

This may be the most tender at the moment, but the obtained graphene requires a very complicated process.

Moreover, the ratio obtained is not very good.

It still doesn't work. Chen Fan can't accept more than ten million machines.

Chen Fan rubbed his hair, shattered all the experimental materials on the table, and then took a deep breath and went out.

Canteen, buy cigarettes.

"Xiaomei."

"Yes, user."

"Am I a failure."

The headset was talking to Xiaomei.

"No, you just want to sit better."

'I found the best thing that can store the battery, but there are flaws in the application. If I can't find graphene and can't find a new way to solve it, then my artificial black hole is destined to be just one Failed batteries, stored electricity and light energy, cannot be passed on. ’

Xiao Mei didn't know how to answer, so she could only choose to be silent.

At the commissary, Chen Fan asked for a pack of cigarettes, took it in his hand, lit it, and took a sip.

Standing on the school playground.

Looking forward.

I don't know what I'm thinking.

"Is that Chen Fan?"

"Yes, I heard that he seems to be studying something weird."

"I know, it is graphene, which has abandoned Cao Yuan for research."

"Isn't that already researched out?"

"Cost, that thing has been researched out, but what about the cost? The most primitive data of graphene was written by Cao Yuan, but the production method is stuck. You know, if graphene is used on a computer, then , You can get a computer hard drive with unlimited expansion."

"What do you mean?"

"It's very simple. When you play any game, you won't get stuck, and it will be so fast that you can't calculate it."

Damn it, is that awesome?

"Isn't it, electric cars are also okay? Wouldn't the oil tycoon cry to death?"

"Don't worry about this. It is something that capitalists need to worry about. I heard that Chen Fan has obtained items that can store a lot of batteries. Graphene actually has it. It is the best conductor for transmitting energy. However, these two are connected in series. There was a contradiction."

"cost?"

Everyone nodded one after another.

Chen Fan got the battery, and Cao Yuan got the material to transfer, but when the two things were combined, the instantaneous value increased countless times.

And Chen Fan's battery has been controlled within the cost of 200,000, or even lower, because one production can produce countless TV originals.

And graphene is stuck here.

The cost of one centimeter of graphene is one thousand dollars.

Then, it doesn't make any sense.

Maybe high-end materials are needed, but Chen Fan himself cannot accept it.

Maybe this is the self-salvation of Xueba.

Single layer graphene

Single-layer graphene (Graphene): refers to a two-dimensional carbon material composed of a layer of carbon atoms that are periodically and closely packed in a benzene ring structure (that is, a hexagonal honeycomb structure).

Double layer graphene

Double-layer graphene (Bilayerordouble-layergraphene): refers to two layers of benzene ring structure (ie hexagonal honeycomb structure) periodically and closely packed carbon atoms stacked in different stacking methods (including AB stacking, AA stacking, etc.) It is composed of a two-dimensional carbon material.

Few layers of graphene

Few-layer: refers to 3-10 layers of benzene ring structure (that is, hexagonal honeycomb structure) periodically and closely packed carbon atoms in different stacking methods (including ABC stacking, ABA stacking, etc.) A two-dimensional carbon material composed of stacks.

Multilayer Graphene

Multi-layer graphene is also called thick-layer graphene (multi-layergraphene): refers to the benzene ring structure (ie hexagonal honeycomb structure) with a thickness of more than 10 layers and less than 10 nm. Stacking, ABA stacking, etc.) stacking constitutes a two-dimensional carbon material.

There are four categories of graphene echoed in my mind.

Looking at these four, Chen Fan held his head helplessly.

Damn, why should this thing be disassembled?

Wait, why disassemble?

Chen Fan seemed to be aware of something.

Then talking to himself, walking on the school playground.

"If you say, don't disassemble, don't separate, just use it?"

"No, I was wrong, maybe conductive particles, all I need are these, not the graphene itself."

"It's not right. Graphene needs conductive particles, so conductive particles, even the graphene itself, and these current technologies, are all nonsense, because all they find is rough graphene."

"Just find the particles, then fuse them together, then all problems will be solved."

Hahahaha, I am a genius.

The pedestrian fans on the side of the road stopped the discussion, they were worried that this genius' thinking would be disturbed.

In the laboratory, Chen Fan brought a small particle collider that he had assembled before.

The energy is activated and the peeling begins.

Find the core.

wait.

Then began to pull people around and run.

Within ten minutes, the laboratory exploded.

The whole house was blown flat, and the surrounding glass was blown to pieces.

Special staff from the school intervened, and Cao Yuan ran over and was punished.

Chen Fan smirked.
