Become Top Student In A Second

Tesla headquarters

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

"Professor Qin, here are the experimental data of our two days. You can have a look." Li Min smiles and hands over a stack of materials to Qin Luo.

Qin Luo would not be polite to anything that could help him. He laughed and took over the information and looked it up carefully.

But the next second, Qin Luo's eyebrows wrinkled.

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

The graphene prepared by mechanical stripping method is of high quality. The graphene produced by mechanical stripping method is generally hundreds of nano or micron graphene flakes, with low production and challenging transfer.

"Well, the quality of composite materials for graphene must be very high. In order to ensure the safety, we choose the mechanical stripping method." Li Min said.

There are five methods to prepare graphene: 1. Redox method; 2. Mechanical stripping method; 3. Liquid phase stripping method; 4. Low pressure chemical vapor deposition method; 5. Atmospheric pressure chemical vapor deposition method.

Each of the five preparation methods has its own advantages. The oxidation-reduction method has the highest efficiency, but the quality of graphene prepared is relatively low.

However, the preparation of graphene by mechanical stripping method is difficult and slow, but the quality of graphene prepared is the highest.

But if we want to compound graphene and oxide, it requires a lot of graphene itself, which is why Li Min chose mechanical stripping method.

"Professor Qin, which method do you want to adopt?" Li Min asked.

"I want to make graphene by redox."

Er

When a word is spoken, all four are startled.

All the people are staring at Qin Luo.

The quality of graphene prepared by oxidation-reduction method is too low to be compounded with other materials.

Another more important point is that redox reaction is the field of chemistry. Does qinluo want to get involved in chemistry.

It's impossible to think about it, right?

"Mr. Qin, you're not kidding, are you?" After hesitating for a moment, Ouchen asked in a voice.

To be honest, he is not optimistic.

"Yes." Qin Luo nodded and said, "as far as the current situation is concerned, this is the fastest way."

It's fast, but it's really useless!

Li Min really didn't want to attack Qin Luo, but now he had to say, "Professor Qin, although the redox efficiency is really high, I have to tell you that graphene prepared by oxidation-reduction can never be compounded with other materials."

"Perhaps?" Qin Luo shrugged his shoulders and said, "how do you know if you don't try?"

"Ah ~", Li Min sighed and said slowly, "if you need any help, please tell me."

"If I can, I need some graphite powder, potassium permanganate, concentrated sulfuric acid, hydrochloric acid..."

Listening to Qin Luo's words, Li Min's mouth twitched.

He can see that qinluo is iron core and wants to prepare graphene by oxidation-reduction method.

But what is potassium permanganate?

Li Min has never heard that it is necessary to prepare graphene!

"Ah ~" Li Min sighed helplessly, and waved with his assistant: "bring what Professor Qin needs. "

the assistant nodded and left.

When he showed up again, he had an extra cart in his hand.

The trolley is full of chemical materials.
