Walking out of the dust-free laboratory, Wu Tao suddenly felt a sense of fatigue welling up in his heart. Counting www.biquge.info, he hadn't been home for nearly a week to rest.

Now that the graphene automatic production line has finally been completed, Wu Tao is even more reluctant to leave. Because before the trial production is verified, even if he goes home to rest, it will be difficult to relax because of this matter.

So Wu Tao decided to carry out trial production today. But before that, he had to cheer up and eat and drink enough.

So he practiced the set of deadly movements designed by Wangcai. After a while, the fatigue in the body immediately disappeared, and in its place, the whole body was full of 3,600 pores.

Then he made a phone call, and not long after, Pei Jun delivered a hearty meal. Wu Tao didn't say a word, picked it up and gobbled it up, and swept it away.

Pei Jun was stunned and cleaned up the remaining garbage, Wu Tao couldn't help but burp and said, "From now on, no one is allowed to disturb me for half a day." ”

"Yes, boss!"

Walking back to the dust-free laboratory, Wu Tao changed into a dust-proof suit and instructed: "No. 1 Intelligence, bring the graphene microchip sample." ”

During these days, in order to ensure the strict confidentiality of the graphene production line, Wu Tao did not call anyone to come over to help. As a result, the No. 1 intelligent robot has become his only labor force, and its performance is very good, making him feel very comfortable to use.

Of course, Wangcai, a lazy dog, also helped a lot. But this guy always comes to a sentence from time to time, 'How rare~', which is very disappointing. So Wu Tao automatically ignored his credit.

"Master, graphene microchip samples, ten copies."

Wu Tao took the topmost one, and this sample was about one square centimeter in area. In order to test this automated production line based on the mechanical peel method, he specially selected ten graphene microchips with different areas to test one by one.

These graphene microsheets are semi-finished products, and many manufacturers have supplied them to the outside world. Its thickness is about 70 nm, and it appears to the naked eye to be only a thin patch. But in the end, the ideal single-layer graphene has a thickness of about 0.35nm.

It looks like an extremely thin piece, but the difference between single-layer graphene and graphene microsheets in various performance parameters such as electrical conductivity and thermal conductivity is worlds apart.

This is the main reason why countries are willing to spend a lot of money to study the mass production method of single-layer graphene.

Taking a deep breath, Wu Tao put 1 square centimeter of graphene microflakes on the raw material table of the production line, and then pressed the start button.

Immediately afterwards, an intelligent robotic arm reached over, accurately pinched the glass substrate of the graphene microsheet, and placed it on the operating table of the mechanical glass. Then the intelligent robotic arm on the periphery automatically seals the entire area around the operator station and quickly draws it into a vacuum environment.

The next peeling process cannot be directly observed with the naked eye. Wu Tao had no choice but to move to the LCD table next to him and look at the rapid movements of several miniature high-precision intelligent robotic arms in the vacuum tank.

After a few minutes, the vacuum-sealed jar is inflated and opened. The graphene microsheets on the glass substrate have disappeared, and the thin film substrate where the final product is located, moved to the detection microscope, immediately reveals nearly 100 single-layer graphene of 1 square centimeter.

From the perspective of the number of exfoliations, it is completely feasible to use intelligent robotic arms to mechanically exfoliate graphene microsheets. I just don't know what the quality of these hundreds of single-layer graphene products is.

The laboratory lacked professional testing tools, so Wu Tao took the first product to Wangcai and said: "Look at it, what is the yield and quality?" ”

Wangcai opened his eyes lazily, and a faint blue light slowly swept across the film substrate, and the test results were quickly obtained.

"Perfectly peeled 75 parts, perfect crystallization structure, free of any functional groups, topological defects and metal ion impurities, 20 parts of peripheral damage, 5 parts of waste."

The results looked good, and Wu Tao continued to put 10 square centimeters of graphene microsheets into the test.

Soon, Wangcai came to the conclusion after testing: "70 parts of perfect peeling, 22 parts of peripheral damage, and 8 parts of waste products." ”

Five minutes later, the third piece was also successfully peeled off. However, the damage rate and scrap rate have increased a little again.

If this continues, isn't it true that the larger the area, the higher the damage rate and scrap rate?

Faced with this problem, Wu Tao couldn't help frowning, and gradually observed the peeling process of the miniature high-precision intelligent robotic arm to find out the reason.

An hour later, Wu Tao loaded the re-optimized graphene preparation database into the super control chip of the intelligent robotic arm. The production line was then restarted and the largest graphene microsheets were directly placed for testing.

This time, the stripping process is longer, because the area is much larger, and the difficulty of stripping is skyrocketing. After about two hours, the whole stripping process is over.

Looking at the single-layer graphene samples on nearly 100 film substrates, Wu Tao couldn't help but sweat. Wangcai scanned them one by one, and gave the test results after a while.

"Perfectly peeled 95 parts, perfect crystallization structure, free of any functional groups, topological defects and metal ion impurities, 5 parts of peripheral damage, 0 parts of waste."

"Oh yes! Great, finally succeeded! Wu Tao immediately jumped up excitedly.

"How rare ......" Wangcai's mantra just spit out two words, and was forced back by Wu Tao's vicious gaze.

Perfect single-layer graphene has been produced, but in order to be publicly recognized by the outside world, it must be tested by an authoritative department.

Once the authoritative department passes the inspection, the infinite potential and value of this graphene automatic production line will be verified.

Thinking of this, Wu Tao instructed: "No. 1 intelligence, seal the last batch of large-area single-layer graphene samples, give me ten copies, and I will take them out of the laboratory." ”

"Yes, master!"

Walking out of the dust-free laboratory, Wu Tao looked up at the sky. After many days of hard work, it finally paid off with success.

The success of this single-layer graphene production line not only directly proves the profound potential of Tianyu intelligent robots, but also will bring earth-shaking changes to the field of new materials.

Once the industrial mass production of single-layer graphene starts, it will be followed by technological progress and innovation in various materials and products. For example, high-energy batteries with high energy density and fast charging speeds, flexible LCD screens that can be folded at will, and the birth of high-performance chips will not be far away.

These are all business opportunities with unlimited potential!

Pei Jun walked over and interrupted Wu Tao's thoughts.

Thinking of the important strategic significance of the graphene production line in the dust-free laboratory, Wu Tao immediately ordered: "Pei Jun, from now on, this small building will be listed as a forbidden place, and no one is allowed to approach the dust-free laboratory." ”

"Yes, boss!"
