Chapter 91 The Great Success
Walking out of the dust-free laboratory, Wu Tao suddenly felt bored.Counting it, he has not been home to rest for nearly a week.

Now that the fully automatic graphene production line has finally been completed, Wu Tao is even more reluctant to leave.Because before he got the verification of the trial production, even if he went home to rest, it would be difficult for him to relax because he was thinking about 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 desperate movements designed by Wangcai.After a while, the fatigue in the body disappeared immediately, replaced by the comfort of the [-] pores all over the body.

Then he made a phone call, and not long after, Pei Jun delivered a sumptuous meal.Without further ado, Wu Tao picked it up and devoured it, sweeping away everything.

Pei Jun cleaned up the remaining rubbish in astonishment, Wu Tao couldn't help belching and said: "From now on, within half a day, no one is allowed to disturb me."

"Yes, boss!"

Walking back to the dust-free laboratory, Wu Tao put on a dust-proof suit and ordered: "Smart No. [-], bring the graphene microchip samples."

During these days, in order to ensure the strict confidentiality of the graphene production line, Wu Tao did not call anyone to help.So the No. [-] intelligent robot became his unique labor force, and it performed very well, making him feel very comfortable to use.

Of course, Wangcai, a lazy dog, also helped a lot.But this guy always says "how rare~" from time to time, which is very disappointing.So Wu Tao automatically ignored the credit for it.

"Master, samples of graphene microflakes, ten copies."

Wu Tao took over the topmost sample, which is about one square centimeter in size.In order to test this automated production line based on the mechanical exfoliation method, he specially selected ten types of graphene microchips with different areas to test one by one.

These graphene microchips are semi-finished products, and many manufacturers have already supplied them to the outside world.Its thickness is about 70nm, and it seems to be only a thin piece to the naked eye.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 microflakes is worlds apart in various performance parameters such as electrical conductivity and thermal conductivity.

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 a 1 square centimeter graphene microchip on the raw material table of the production line, and then pressed the start button.

Immediately afterwards, an intelligent robotic arm stretched over, pinched the glass substrate of the graphene microflakes precisely, and placed it on the operating table of the mechanical glass.Then the peripheral intelligent robotic arm automatically seals the entire operating table and quickly evacuates it into a vacuum environment.

The following peeling process cannot be observed directly with the naked eye.Wu Tao had no choice but to move to the LCD display stand next to him, watching 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 microflakes on the glass substrate have disappeared, and the film substrate where the final product is located, moved under the inspection microscope, and nearly a hundred single-layer graphene of 1 square centimeter appeared immediately.

From the point of view of the quantity obtained by peeling, it is completely feasible to use intelligent robotic arms to mechanically peel graphene microsheets.I just don't know the quality of the hundred or so single-layer graphene products.

The laboratory lacks professional testing tools. Wu Tao brought the product he got for the first time to Wangcai and said, "Look at the yield and quality?"

Wangcai lazily opened his eyes, a faint blue light slowly swept across the film substrate, and soon got the test result.

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

The result looked pretty good. Wu Tao continued to put 10 square centimeters of graphene microflakes into the test.

Soon after the inspection, Wangcai came to a conclusion: "70 parts were perfectly peeled off, 22 parts were peripherally damaged, and 8 parts were waste products."

After 5 minutes, the third piece was also successfully peeled off.However, the damage rate and scrap rate increased a little again.

If this continues, wouldn't the larger the area, the higher the damage rate and scrap rate?

Faced with this problem, Wu Tao couldn't help frowning, and observed the stripping process of the miniature high-precision intelligent robotic arm step by step 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.Then the production line was restarted, and the graphene microchips with the largest area were directly put in for testing.

This time the stripping process took longer, because the area was much larger, and the difficulty of stripping rose exponentially.After about two hours, the entire stripping process was over.

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

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

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

"How rare..." Wangcai had just uttered the two words before being forced back by Wu Tao's vicious gaze.

The perfect single-layer graphene has been produced, but if it wants to be publicly recognized by the outside world, it must be tested by an authoritative department.

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

Thinking of this, Wu Tao ordered: "Smart No. [-], 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.Days of hard work finally paid off.

The success of the 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 industrialized mass production of single-layer graphene starts, technological progress and innovation of various materials and products will follow.For example, high-energy batteries with high energy density and fast charging speed, 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 came 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 area, and no one is allowed to approach the dust-free laboratory."

"Yes, boss!"
