C423 Oxidization Regeneration Method to Prepare Graphene

Tesla Company Headquarters...

Qin Luo had already put on his work clothes and walked into the laboratory.

"Professor Qin, this is the experimental data for the next two days. You can take a look." Lee Min smiled and handed a stack of information to Qin Luo.

Qin Luo would not be polite to things that could help him. He smiled and took the information and started to read it carefully.

But in the next second, Qin Luo frowned.

"Professor Lee, are you using the mechanical stripping method?"

The mechanical stripping method was graphene preparation. The graphene produced was of high quality. The graphene extracted was usually hundreds of nanometers or micrometers graphene layer. The output was low, and the transfer was challenging.

"Well, the composite material has to be very high in the quality of graphene. In order to ensure that nothing goes wrong, we chose the mechanical stripping method." Lee Min said.

There were five commonly used methods to prepare graphene. One was the oxygen restoration method, two were the mechanical stripping method, three were the liquid phase stripping method, four were the low pressure chemical vapor deposition method, five were the normal pressure chemical vapor deposition method.

The five methods had their own merits. Among them, the oxygen reduction method had the highest efficiency, but the graphene quality was relatively lower.

The mechanical stripping method was difficult to prepare, and its efficiency was slow, but the graphene quality produced was the highest.

But to compound graphene and oxide, the requirement for graphene itself was extremely high. This was also the reason why Lee Min chose the mechanical stripping method.

"Professor Qin, what method do you want to use?" Lee Min asked.

"I want to restore the graphene by oxygen."

Uh...

As soon as the words came out, the four were shocked.

Everyone widened their eyes and stared at Qin Luo.

Oxidizing restoration method, the quality of the graphene produced by this method was too low and could not be combined with other materials.

There was another more important point. Oxidization restoration reaction was in the field of chemistry. Could it be that Qin Luo still wanted to intervene in chemistry?

It was impossible even if he thought about it.

"Qin, are you joking?" After a moment of hesitation, Ou Chen asked.

To be honest, he did not think so.

"En." Qin Luo nodded and said, "Looking at the current situation, this is the fastest way."

It was fast, but it was useless!

Lee Min really did not want to give Qin Luo a blow, but he had to say it now. " Professor Qin, although the efficiency of the oxygen restoration is very high, I have to tell you. The graphene produced through the oxygen restoration can't be combined with other materials."

"Maybe?" Qin Luo shrugged and said, "How do you know if you don't try?"

"Sigh." Lee Min sighed and said slowly, "If you need help, tell me."

"If possible, I need some graphene powder, high manganese acid, concentrated sulfuric acid, and salt acid."

Hearing Qin Luo's words, the corner of Lee Min's mouth twitched.

He finally realized that Qin Luo was determined to use the oxygen restoration method to prepare graphene.

But what the hell was the high manganate?0

Lee Min had never heard of the need for graphene!

"Sigh." Lee Min sighed helplessly. His assistant waved his hand and said, "Bring what Professor Qin needs. “

The assistant nodded and left.

When he reappeared, a handcart had already appeared in his hand.

The handcart was filled with all kinds of chemical materials.
