Chapter 423 Preparation of Graphene by Redox Method

Tesla's corporate headquarters...

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

"Professor Qin, here is our test data for the past two days, you can take a look." Li Min smiled and handed a stack of data to Qin Luo.

For things that can help him, Qin Luo is not polite, smiled, took over the information and checked it carefully.

But in the next second, Qin Luo's brows furrowed.

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

The graphene produced by mechanical exfoliation method is of high quality. The exfoliated graphene is generally hundreds of nanometers or micrometers of graphene sheets, the yield is very low, and the transfer is also very challenging.

"Well, the quality of graphene for the composite material must be very high. In order to ensure foolproofness, we chose the mechanical peeling method." Li Min said.

There are five commonly used methods for the preparation of graphene, 1. redox method, 2. mechanical exfoliation method 3. liquid phase exfoliation method 4. low pressure chemical vapor deposition method 5. atmospheric pressure chemical vapor deposition method.

The five preparation methods have their own merits, among which the redox method has the highest preparation efficiency, but the quality of the prepared graphene is relatively low.

However, the mechanical exfoliation method is difficult to prepare and the efficiency is slow, but the quality of the prepared graphene is the highest.

However, in order to compound graphene and oxide, the requirements for graphene itself are extremely high, which is why Li Min chose the mechanical exfoliation method.

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

"I want to make graphene through redox."

Uh……

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

Everyone's eyes widened, staring at Qin Luo.

Redox method, the quality of graphene prepared in this way is too low to be compounded with other materials at all.

There is a more important point, redox reaction is the field of chemistry, Qin Luo still wants to get involved in chemistry.

It's impossible to think about it, right?

"Student Qin, aren't you joking?" Ou Chen asked aloud after hesitating for a moment.

To be honest, he is not optimistic.

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

It's almost fast, but it's really doing nothing!

Li Min really doesn't want to attack Qin Luo, but now he has to say: "Professor Qin, although the redox efficiency is indeed very high, I have to tell you that graphene prepared by redox is impossible to compare with other Composite materials."

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

"Hey~" Li Min sighed and said slowly, "If you need any help, just tell me."

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

Hearing Qin Luo's words, Li Min's mouth twitched.

He could see that Qin Luo was determined to use the redox method to prepare graphene.

But what the hell is potassium permanganate?

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

"Hey~" Li Min sighed helplessly, and waved his hand along with the assistant on the side: "Bring what Professor Qin needs."

The assistant nodded and turned to leave.

When he reappeared, there was an extra trolley in his hand.

The cart is full of various chemical raw materials.
