Chapter 85 on graphene exfoliation methods

"Five million!"

Fang Zicheng looked at Han Lingyang in surprise, he had never heard of a laptop product selling for more than five million in his life. Pen "Fun" Pavilion www.biquge.info

"If I use graphene for batteries and screens, the price will be even more expensive."

Han Lingyang said lightly.

Originally, Han Lingyang was going to make transparent electronic screens and use graphene as the basic material, but because Han Lingyang had not yet mastered a better graphene stripping technology, he temporarily gave up this idea.

"Old Han, will you still peel off graphene?"

Fang Zicheng looked at Han Lingyang even more incredulously and asked.

"Wasn't the stripping of graphene stripped out in 2004, as if physicists Andrei Geim and Konstantin Novoselov of the University of Manchester in the United Kingdom successfully isolated graphene from graphite using micromechanical exfoliation and proved that it can exist alone, for which they jointly won the 2010 Nobel Prize in Physics."

Han Lingyang said seriously.

"The micromechanical exfoliation method is only suitable for experiments, if you want to strip a large amount of graphene, do you need a new exfoliation technology?"

Fang Zicheng looked at Han Lingyang and asked.

Han Yudie on the side was listening quietly, as a scholar, of course he knew what the "graphene" discussed by his brother Han Lingyang and Fang Zicheng was.

Graphene is a honeycomb planar film formed by the sp2 hybrid of carbon atoms, it is a quasi-two-dimensional material with only one atomic layer thickness, so it is also called single-atomic layer graphite. The thickness of graphene is about 0.335nm, and there are different ups and downs depending on the preparation method, usually about 1 nm in the vertical direction and about 10nm to 25nm in the horizontal direction, which is the basic structural unit of all carbon crystals except diamond, including zero-dimensional fullerene, one-dimensional carbon nanotubes, and three-dimensional body-oriented graphite.

And graphene is called "black gold", it is the king of new materials in the 21st century!

"Therefore, I have not yet mastered a mature graphene stripping method, otherwise I would have made a transparent electronic screen for Yudie."

Han Lingyang spread his hands and said helplessly.

"Scientists don't all need to be imaginary and put into experiments, you can try exciting peeling, chemical peeling or something?"

Fang Zicheng didn't know much about this knowledge, so he said blindly.

"Please, scientific and technological research requires a rigorous attitude, what laser stripping, aren't you talking nonsense."

Han Lingyang glared at Fang Zicheng.

At present, there are only three main methods for graphene exfoliation in the world: micromechanical exfoliation, redox and SIC (emery) epitaxy.

In fact, regarding the stripping method of graphene, with Fang Zicheng's reminder, Han Lingyang can learn and absorb it the next time he enters the high-dimensional space.

And in the 21st century, as a high-tech company, if you don't study graphene, it is really not in line with the main trend, Han Lingyang feels that it is time to put the preparation, production and use of graphene on the agenda, which not only further promotes the progress of science and technology, but also once graphene is really used, it can make people's lives more convenient.

"In fact, there are many kinds of stripping methods for graphene, but we have not explored them, and there is always one that is very suitable for commercial production and use, and a scientific and technological revolution belonging to graphene will inevitably break out at that time."

Han Lingyang said confidently.

Of course, Han Yudie and Fang Zicheng think that Han Lingyang is talking nonsense, because in the future, graphene, a new material, will definitely be widely used.

"Okay, I think you guys think I'm talking nonsense, so let's get back to business, shall we?"

Han Lingyang shrugged helplessly and said.

So Han Yudie and Fang Zicheng watched Han Lingyang quietly and didn't continue to listen to him talk about the magic of this laptop.

"Yudie,I give you this laptop is made by me personally,It has a high security authority,And it's also my personal research and development"Future System",You can't install and use other systems,Such as Microsoft's and Apple's or something,They're too rubbish,As for how to use the "Future System",You can ask your sister-in-law tonight,You can also follow the tutorial after booting,In addition, this time we installed a product that our future technology company is going to release this time-Computer Intelligence System,Of course, you're an upgraded version.,It's much stronger than what we're going to release.,After all, they're used in ordinary computer systems.,And you're using this in a powerful "future system".,Eh, do you understand? ”

Han Lingyang said a lot in one breath, and then looked at his sister Han Yudie and asked.

Han Yudie was stunned for a while before absorbing what Han Lingyang said, and then held her chin and asked cutely: "Brother, why do you want to ask your sister-in-law how to use your "future system"?" ”

"You're stupid, because your sister-in-law has used it, I once gave her a computer that I developed alone, which is similar to yours, but lower than yours."

Han Lingyang knocked on Han Yudie's little head and said.

"Oh, so that's the case, my sister-in-law is so busy, I'd better learn the tutorial by myself, hehe." Han Yudie said with a smile.

"How about it, do you like this gift that my brother gave you?"

Han Lingyang asked with a smile.

"I like it, of course I like it, tsk, look at this workmanship, and then look at this configuration......"

Fang Zicheng was also about to take out the laptop that Han Lingyang gave to Han Yudie to take a look, but Han Lingyang snapped his hand and beat him back.

"Give me five million labor fees another day, and I'll make you one, how about it?"

Han Lingyang looked at Fang Zicheng and kept raising his eyebrows.

"Five million, I'm full, it's better to buy a villa by the sea for my family Xiaoxuan."

Fang Zicheng said disdainfully.

"Zicheng, do you want to buy me a villa?" Suddenly, in the kitchen, Shi Bixuan poked her head out and asked with a smile.

"Ah, you must have heard it wrong, I still owe Lao Han money for a Bugatti Veyron supercar, how can I afford to buy a villa."

Fang Zicheng hurriedly shook his head and said.

Fang Zicheng's quick reaction, coupled with Shi Bixuan's muttering mouth, caused everyone to laugh for a while.

"Zicheng, what are you afraid of, isn't it just a five-million villa? When our company pays dividends at the end of the year, can you still lose your money? ”

Han Lingyang patted Fang Zicheng's shoulder and said with a smile.

Fang Zicheng's face sank, feeling that this matter was unreliable, rather than waiting for the company's year-end dividends, it was better to do a few more product designs in his spare time to earn some extra money.

"Brother, thank you for the gift, I wish you a smooth new product launch tomorrow and the product is selling well!"

Han Yudie said a few good words, and then took the high-tech laptop from Han Lingyang's hand and carefully looked at its uniqueness.
