Su Cheng and his entourage left the laboratory, Ma Kai followed behind him, and said with a wry smile: "Mr. Su, you have offended Yang Yihong by doing this." Pen %Fun %Pavilion www.biquge.info"

"Did I offend him?" Su Cheng turned his head to look at Ma Kai and said strangely: "Didn't he offend me?"

What does it mean that Su Cheng offended Yang Yihong? Ma Kai said something wrong, it was obvious that Yang Yihong was offending Su Cheng.

Now the entire factory is Su Cheng's, and the laboratory is actually considered to be, Su Cheng did not immediately let a few robots throw the equipment out, which is already considered to be a lot of face for Yang Yihong.

Su Cheng's answer made Ma Kai laugh, but he also felt the open-mindedness of the big boss in his heart and admired it.

"Mr. Su, no matter what, but I think that if you strictly order Yang Yihong to move out of the laboratory, he will definitely make a fuss about this matter, and if it is not good, he may also publish a Weibo and shoot at our company on the Internet. Ma Kai worried.

"Then do you think we have a better way than this?" asked Su Cheng. If there are no outsiders in the graphene factory, the laboratory will naturally not continue to exist.

"Yes, some time ago, when you acquired the graphite factory, I learned about the preparation of graphene, large pieces of graphene are very difficult to produce, since Yang Yihong can prepare coin-sized graphene, in fact, this is a huge technological breakthrough, even if our company raises him, in fact, it will not lose ......"

Ma Kai expressed his opinion, Su Cheng nodded when he heard it, and then shook his head again.

"I don't like his kind of graphene. Su Cheng teased.

"You, really don't like it?" Ma Kai was stunned for a moment, he thought that in the laboratory before, Su Cheng was deliberately mocking Yang Yihong.

The corners of Su Cheng's lips hooked, and he said casually: "How about the production and sales of our company's sleeping pillows?"

Ma Kai hurriedly replied: "It deserves to be the first in the province!"

With the continuous fermentation of advertising and the spread of good word of mouth, the daily sales of Chaowei Technology Company's sleeping pillow have stabilized at more than 1 billion, and the company's assets have also exceeded 10 billion.

In terms of sales alone, it may not be as good as the giant group outside the province, but in Sichuan Province, it is definitely the first.

Of course, the data has not yet been released, and people from the outside world actually don't know the current situation of Chaowei Technology Company, only that this pillow is very popular.

"The sales of this graphene may be even hotter than sleeping pillows. Su Cheng said.

"This ......"

Ma Kai was stunned, these words came out of the mouth of the big boss, and he was skeptical at first, but when he thought of Su Cheng's everything, he was extremely convinced.

"Mr. Su, what do you mean, do we have the technology to make large graphene films?" asked Ma Kai.

"There are some things that you just need to know in your heart, and this is a trade secret. Su Cheng patted Ma Kai on the shoulder and said, "Do a good job, I am optimistic about you, when the company grows bigger in the future, you may be the general manager of a branch." ”

Yes?

Ma Kai was startled, and Su Cheng's words, like a heavy hammer, slammed into his heart, making him breathe short, and his face was swollen red with excitement.

"Mr. Su, don't worry, I will work hard and will definitely not disappoint your expectations of me. ”

Ma Kai didn't expect that the big boss actually said that he would have the opportunity to promote himself to be the general manager of a branch in the future, which also took too much care of him, right?

Thinking of Xiao Minghang, who had already gone to the sea, Ma Kai was full of excitement and secretly decided that he must work hard to win Su Cheng's approval as soon as possible.

The time was close to noon, and Su Cheng also walked around the factory and walked around all the areas.

When I arrived at the office building, eight small robots were already waiting there.

When he went up to ask, Su Cheng learned that the hundreds of employees had all packed up their things and left at this time, and as for some disobedient guys who wanted to make trouble during the period, they were all suppressed by them by forceful means.

After the matter was resolved, Su Cheng found a closed production workshop and let the four small workers and robots guard outside, not allowing anyone to enter.

Then let six small workers throw all the machines in the workshop.

After finishing everything, the time came to two o'clock in the afternoon, and Ma Kai also bought a lot of meals for the robots according to Su Cheng's instructions.

After eating, in a very empty workshop with blue walls and dark floors, six small workers stood behind Su Cheng.

Bang!

There was a loud bang, and the whole workshop trembled slightly.

Suddenly, in the originally empty workshop, a huge graphene production line had appeared in front of Su Cheng's eyes.

"Oh my boy, this guy is so big!"

Originally, Su Cheng thought that the graphene production line should not be large, after all, graphene itself is a nano-scale material, but when he saw this production line with a length of nearly 20 meters, a width of 3 meters, and the highest place was 6 meters, and the whole body was painted blue, he knew that he had made a mistake.

This is still a behemoth, even larger than the production line of the tea machine.

Fortunately, the open space in this workshop is large enough, otherwise Su Cheng has no doubt that this production line can squeeze the walls.

The whole production line consists of four parts, the first part of the equipment has two units, which are used to synthesize artificial graphite, and can also prepare various substrates.

The second part consists of three machines, which are used to laser wash the graphite and further process the substrate required for graphene.

The third part is used for high-precision exfoliation of graphene, with a total of four equipment.

Graphene, a black gold material, has a broad future in the future, but the road is tortuous, and there are four common methods for preparing graphene in the world.

Micromechanical exfoliation method, epitaxial growth method, chemical vapor phase precipitation CVD method, graphite oxide reduction method.

Among them, the CVD method is most likely to be applied to large-scale mass production in the future, but the shortcomings are obvious, the perfect form of graphene can not be obtained, and the preparation is a graphene film, although the number of layers can be as small as a single layer, but it cannot form crystals, and the appearance looks smooth and coherent, but in fact, at the molecular level, there are large cracks, so the electrical properties will be much worse.

At the beginning, Samsung Group prepared a graphene wafer with a diagonal of 30 inches, which was the CVD method.

As for the rest of the methods, the cost is too high, and it is okay to make samples, but large-scale production is impossible.

Different from the preparation process of graphene that is common in the world today, the production line equipment produced by the Science and Technology City, in the preparation of graphene, directly uses nano-level technology to peel, link and mosaic graphene, and manufacture single-layer, double-layer and 3-10 multi-layer graphene films or wafers and even crystals from the molecular level.

In the third part in front of me, there are four blue round high-barrel devices, in which trillions of nano-scale robots are sleeping, and only when they are powered and charged can they effectively and quickly prepare graphene.

As for the fourth part, it is the final washing and polishing equipment of graphene, and of course, the most important thing is to embed graphene on different substrates.

Since graphene is a two-dimensional material, at the nanometer level, a single layer of graphene cannot be seen with the naked eye at all, and it is easy to be damaged, and it must be inlaid with various substrates.

Of course, if the technology is sufficient, graphene can be theoretically crystallized, but this is difficult, because once a single layer of graphene overlaps too many layers, it is not graphene, but graphite.

Therefore, it is very difficult to make graphene maintain the characteristics of two-dimensional materials without borrowing the substrate, at least at the current science and technology city has not opened up that kind of technology.

The huge production line stood in the workshop, and Su Cheng's heart slowly surged unconsciously.

"Plant batteries, solar power banks, superchargers, ultra-micro transistors, ultra-thin transparent mobile phones...... These things are the most promising graphene products in the next few years, and if they are in operation, the money will come with a bang. ”

Compared with sleeping pillows, graphene will have a larger market in the next few years, operate well, cover all industrial chains around the world, and be worth more than trillions?

And at this moment, who would have thought that a large graphene wafer, which basically only exists in the laboratory, can be perfectly manufactured in such a small workshop.

After calming down, Su Cheng did not hesitate, and immediately asked the small worker robot to start operating the graphene production line, where he wanted to witness the birth of the first graphene film of Chaowei Technology Company.
