425: C425 The Quality Was Very High

C425 The Quality Was Very High

He never thought Qin Luo could successfully produce graphene.1

"Is it because of the high manganate?"

Lee Min asked in shock.

"Yes, through the use of the high manganese acids, the carbon molecular structure in the graphite is gradually turning into a plane molecular with positive electricity." Qin Luo said with a smile.

Hearing Qin Luo's words, Lee Min suddenly understood. As a physics and chemistry expert, his accumulation of knowledge had reached a shocking level. He had never thought of this before, but after Qin Luo's reminder... The entire preparation process instantly became clear.

"So the sulfuric acid root ions and the sulfuric acid molecules gradually enter the inkstone layer, forming a merger between the sulfuric acid and inkstone layer?" Lee Min asked.

"Well, the graphene quality produced by the regenerative reactions of the hydrogen peroxide is relatively low. Most of the reason is that the sulfuric acid ions float on the surface and do not enter the graphite layer, but use the high manganate to act as a catalyst. Creating a plane molecular can directly solve this problem! " Qin Luo nodded and said.

At this moment, the entire scene was silent. Everyone, including Lee Min, stared at Qin Luo with their mouths agape.

They couldn't believe their ears.

If they hadn't seen it with their own eyes, they wouldn't have believed it no matter what they said.

There wasn't a problem that could be solved in the entire world, and it was solved by Qin Luo with a small amount of manganese acid.

After a long while, Lee Min was the first to come back to his senses. He looked at Qin Luo with a complicated look in his eyes.

It was this half-grown child in front of him who solved the problem that had troubled the physics world for so many years.

Thinking of this, Lee Min sighed deeply. He cupped his hands to Qin Luo and said with a smile, "Listening to your words is better than reading for ten years. I am convinced."

"Uh... Professor, don't say that. I was just lucky." Qin Luo said shyly.

Being praised by a famous professor made Qin Luo's handsome face slightly red.

Lucky?

Lee Min shrugged and smiled. During the physics experiment, good luck was not excluded, but good luck was based on the corresponding strength.

If you didn't have the ability, not to mention catalyzing the reaction with the high manganate, you wouldn't even know how to prepare graphene.

"Luck is also a part of strength. Qin has this strength." Lee Min said with a smile.

A brilliant smile emerged on Qin Luo's face when he heard Lee Min's words.

"By the way, let's start testing the graphene quality." Lee Min said.

After a period of cool down, the graphene in the beaker had solidified, and now it was time to test its quality.

Qin Luo nodded, carefully took out the graphene in the beaker, and then put it into the infrared spectroscope.

A few minutes later, an infrared spectroscope appeared in front of everyone.

Maximum absorption: 3,000 ~ 3700 cm

In the range of 1723, 1382, 1221, and 1055 cm-1, a absorbing peak appeared... and a lengthened vibration peak -C = 0 appeared.

The stretching and contracting peak in the 1382 OH shapeshifting vibration peak became very weak. This result proved that graphene had been successfully prepared.

And the graphene produced was of a relatively high quality, even comparable to the graphene produced by mechanical stripping.

"Gulp ~" Looking at the infrared spectrum data in front of him, Lee Min carefully swallowed his saliva.
