Chapter 278 Breakthrough

On November 2026, 11, Wu Hao brought Dabin to the R&D center of Zhang Li Company. After learning about Dabin's identity, the other party expressed his willingness to rent out the laboratory, but the price was not low. One month included all expenses. 10 million.

This is less than what Wu Hao expected. Even if it is rented for a year, it is only more than 2000 million, which he can afford.

However, basic research takes a lot of time, and it is really hard to say when results will be achieved. Wu Hao can only wait and see the results. After all, he knows nothing about specific scientific research methods.

The laboratory is somewhere in the northwest, and Wu Hao has to rush back to work in Pengcheng, so the research and development can only be handed over to Dabin.

Before leaving, Wu Hao found a restaurant and set up a table of hand-caught mutton. He wanted to have a drink or two with Dabin and chat with him by the way.

"Dabin, the laboratory has been rented out, and I will leave the rest to you."

"Brother, thank you for trusting me!... I will definitely do my best."

The two drank a cup, and then ate meat and soup.

"By the way, Gu Fan asked me to bring you a sentence. I suggest that you innovate a production method. Don't blindly pursue a large-area perfect finished product. You can try a small-sized one. First, you can make a graphene sheet with a photolithographic capacitor. , and then challenge a larger area."

Wu Hao used Gu Fan's mouth to speak his own words. He didn't know much about this aspect, but sometimes this breakthrough point is often not included in the standard answer.

Da Bin took a sip of liquor and said, "Gu Fan actually talked to me, and I know what he means, but in the professional field of graphene, I still hope to try my own way of thinking first, after all, this kind of research still needs a lot of work. It takes a rigorous attitude to succeed.”

The atmosphere at the wine table was a bit depressing, which was not a good sign. No matter whether things are successful or not, one needs to have momentum to face difficulties.

"Hehe, if this graphene can be easily torn off like mutton with your hands, that would be great!" Wu Hao joked.

"Hahaha, don't say it, it really came off just like that, but there is no way to tear it perfectly. The van der Waals force between graphene is not as strong as you think."

Da Bin was amused, and the atmosphere on the wine table changed and became much more relaxed.

"Look at this layer of meat film, torn off from the bone, it's translucent and thin enough, do you think it's perfect?" Wu Hao continued joking.

Holding a mutton chop in his hand, he tore off the half-fat mutton and chewed it. The bone was covered with a layer of fascia, which he tore off with his hands and showed it to Dabin.

"Hmm... It kind of means that, but you are cheating. The fascia torn from the bone is not counted, but such a thin piece has to be torn from the meat!" Dabin, like Gu Fan, was studying With the same obstinacy.

"Strictly speaking, this fascia is also meat, and it is perfect meat. The meat next to the bone is the most fragrant. This layer of fascia is obviously the easiest to tear off. You have to tear that big piece of meat." Wu Hao Continue to joke, and by the way, satirize Dabin's rigidity.

"I really can't say enough about you, come here and we'll do it!" Dabin smiled wryly, feeling quite unreasonable when a scholar meets a soldier.

"It's a pity that there are no bones in this graphene, otherwise a perfect piece of 'fascia' would definitely be torn off!" After several cups, Wu Hao was a little floaty.

"Who said that there are no bones in graphene, and the oxidized graphite on the surface, the oxidized surface layer is like bones, but the bones are irregular and not smooth, and the perfect 'fascia' cannot be torn off!"

Dabin continued to talk along the topic, it was just nonsense anyway.

"Isn't graphene easily oxidized into carbon dioxide?" Wu Hao was curious.

"No, carbon dioxide will only be turned into carbon dioxide during combustion or metal oxidation and reduction." Dabin began to popularize science.

"Redox? Give me an example." Wu Hao asked.

"For example, when hot copper oxide comes into contact with graphite, it will get carbon dioxide and copper." Dabin said casually.

"It would be great if we could make a layer of two-dimensional copper oxide and oxidize graphite layer by layer like peeling after heating." Wu Hao had a whimsical idea.

"Impossible. First of all, it is necessary to make a perfect copper oxide sheet, which is impossible with the current technology. In other words, it is more difficult than producing graphene."

Dabin denied the possibility of this idea. Many people have thought about this oxidation stripping technology, but none of them are successful.

"That's right. After all, single-layer graphene is very tough, and the shape between each layer is only maintained by van der Waals force. This force is actually very small. Copper oxide is different. It is the force between molecules, and it is more difficult to peel off." Wu Hao still did some homework, he knows where the key points of the problem are.

Single-layer graphene is very tough in terms of physical properties, and can be greatly stretched in the transverse section, but it is prone to tearing and fracture in the longitudinal direction, which is determined by physical properties.

It's a bit like a plastic film. It's hard to break when stretched horizontally, but once there is a small gap, the film can be torn in half with a light tear from there.

"You got to the point. This is a very contradictory place. Single-layer graphene has super-strong physical properties and is also very stable chemically. Because of this, it is difficult to prepare large-scale graphene with a perfect structure. Small-sized single-layer graphene, because you can only use force in the horizontal direction, the operation is not precise enough, and the blank will be damaged immediately.”

Dabin summed up the problems and also pointed out the difficulties of this work. Scientists all over the world have been exploring for many years, but they have not found a perfect solution.

"It would be great if graphene could also be passivated, so that it can be passivated layer by layer." Wu Hao poured himself another glass, ate meat and drank heavily, and bragged by the way.

"This is the chemical stripping method. Now there seems to be no other good method except through oxidation. However, the oxidation of carbon is very fast and it is not a controllable process. Up to now, no one has found what you said. phenomenon."

"However... it may be possible to perform an instantaneous and controllable exposure oxidation operation through some kind of light-sensitive oxidant. After all, the current laser technology is very perfect."

Da Bin became thoughtful. He was recalling the details of the previous experiment. In that successful experiment, the perfect piece of graphene product was thrown aside by him at the beginning, because he felt that the piece of graphene The test product is definitely not likely to be successful.

Then the sample was thrown there for a few days, and finally he took it to wash it by accident, and after removing the surface residue with tape method, he got a successful work.

Could it be that he accidentally used some kind of medicine that he didn't remember, and happened to use the right amount, and after several days of exposure and oxidation reaction, the perfect work was produced?Dabin began to mutter in his heart.

"Come on, let's do it!" Wu Hao raised his glass, but Da Bin waved his hand to signal not to disturb him yet.

After being silent for more than ten minutes, Dabin suddenly got up and left his seat, and left without looking back.

Wu Hao was stunned, but he soon realized that maybe this man had thought of some technical details to make such a move.

After clearing the food on the table and paying the bill, Wu Hao rushed to the airport, and left to fate for the rest.
