After staying on the roof for a while, Lin Xuan pulled a spider silk and fell from the roof to the window of his office, and then returned to the office from the window.

Taking off Spider-Man's coat, Lin Xuan looked at the time, it was almost one o'clock in the morning, and he didn't have much to sleep, so he lay on the sofa and began to think about the next development direction of the company.

Although Lin Xuan had said before that Xuanyu Technology's next goal was to develop a mobile phone operating system, he did not say what kind of system it was, nor did he say what the real purpose of this system was.

In fact, the reason why Lin Xuan wanted to develop a mobile phone operating system was to apply it to the new type of mobile phone he wanted to produce-the kind of mobile phone that was infinitely close to the transparent screen used by Tony in the "Iron Man" movie.

Because Lin Xuan knows very well that relying solely on a mobile phone operating system, even if he has Apple's AppStore authorization, it will be difficult for him to open the market.

But if he produces the kind of transparent screen phone in the "Iron Man" movie, and carries a smarter, smoother and more stable operating system, he can definitely make this phone a blockbuster.

Quickly opened up his mobile market, so that he can continue to launch new computers with 3D operating systems and even smart homes in the future.

Of course, Lin Xuan also knows that whether he wants to produce the kind of transparent mobile phone, or the computer with a three-dimensional operating system, or a smart home, the first thing to solve is the hardware problem.

For example, transparent touch screens, such as batteries with larger capacity and smaller size, such as smaller but more powerful CPUs, and heavier chips......

Without a good hardware support, even if he researches a great mobile phone operating system, it is still a small horse-drawn cart and cannot play an effective role.

With the current level of hardware, it is obviously impossible to meet Lin Xuan's needs, so he needs to make a revolutionary improvement in the performance of various hardware.

The breakthrough point for improvement is the new materials that most countries are currently spending huge amounts of money on research and development, and it is also known as the "king of materials" and "black gold" - graphene.

Graphene is a two-dimensional crystal that is stripped from graphite materials and composed of carbon atoms with a thickness of only one atom. It is the thinnest and strongest material available, with a breaking strength 200 times higher than that of the best steel. If a hammock is made of graphene with an area of 1 square meter, it weighs less than 1 milligram and can withstand a one-kilogram cat.

At the same time, it has good elasticity, and the stretch range can reach 20% of its own size.

And graphene can also replace silicon to create better-performing ultra-miniature transistors for the supercomputers of the future. Computer processors made of graphene also run hundreds of times faster than existing ones.

In addition, graphene is almost completely transparent, absorbing only 2.3% of light. On the other hand, it is so dense that even the smallest gas atoms cannot penetrate it.

These features make it ideal as a raw material for transparent electronics, such as transparent touch displays, light-emitting panels, and solar panels.

Not only that, graphene can be applied to the battery field.

As we all know, the development of batteries is not only slowing down the development of mobile electronic devices such as mobile phones, but also the development of many industries, including new energy, such as electric vehicles.

Of course, battery technology has also been making breakthroughs, not so much that batteries have slowed down the development of all walks of life, but that all walks of life are developing too fast, and battery technology can not keep up.

The battery has undergone more than ten years of development, and the rated capacity has indeed more than doubled, but in just seven or eight years, the performance of the CPU has increased by about 50 times, and the performance of the GPU has increased by more than 85 times.

Therefore, battery life is the biggest obstacle for mobile phones at present, if one day, it can produce batteries with larger capacity and faster charging and discharging speed.

Then it will definitely bring a revolutionary change to the mobile electronic equipment industry, and even affect the field of electric vehicles, so that electric energy can truly replace the existing energy, so that electric vehicles can really replace the existing internal combustion engine vehicles.

And the breakthrough that changed all this is also in graphene.

If the capacitor battery made of graphene is charged and discharged at least 1,000 times faster than ordinary batteries, and the graphene battery of the same volume is several times or even more than ten times higher than the power storage of lithium batteries.

The service life of the battery can also be several times longer than that of the lithium battery, and its cost is only about 20% of the current lithium battery.

It can be seen why graphene is called the king of materials.

Of course, in the memory of Iron Man obtained by Lin Xuan, there is a material that is better than graphene, which is a synthetic nanomaterial that is improved on the basis of graphene.

Its performance is dozens of times that of graphene, but the equipment required to prepare this material is still difficult to manufacture with the current technical level and materials.

Therefore, Lin Xuan can only use graphene to upgrade the existing scientific and technological technology and production equipment to a new height, and then further prepare more excellent materials.

Although graphene is good, and the raw materials are extremely cheap and abundant, as we all know, the preparation technology of graphene is not mature.

At present, the most common preparation methods are mechanical exfoliation, redox method, SiC epitaxial growth method and chemical vapor deposition method.

Among them, the production efficiency of mechanical stripping method is too low, and although the redox method is simple to operate and has high output, the product quality is low.

Although the SiC epitaxial method can obtain high-quality graphene, this method has high requirements for equipment and still cannot achieve mass production.

The most likely method to achieve industrial preparation of high-quality, large-area graphene is chemical vapor deposition, but unfortunately the cost of preparation at this stage is high, and the process conditions need to be further improved.

Therefore, the preparation technology of graphene is a difficulty that all scientists in this field are trying to overcome.

However, Lin Xuan has obtained Iron Man's memory, but he has a very mature graphene preparation technology, which is also different from all existing preparation technologies.

The principle is to directly break the van der Waals force between different layers of graphite, and then make the graphite crystals naturally peel off countless graphene materials.

It is important to know that in a graphite crystal, the carbon atoms in the same layer are hybridized with sp2 to form covalent bonds, and each carbon atom is connected to the other three atoms with three covalent bonds. Six carbon atoms form a regular hexagonal honeycomb-like structure on the same plane, and stretch into a lamellar structure, and this monolayer structure is actually graphene.

Moreover, the chemical bond length formed between the carbon atom and the carbon atom here is 142pm, which belongs to the bond length range of the atomic crystal, and the bond between the carbon atoms is very strong and extremely difficult to break.

The graphite crystal can be understood as a complex crystal formed by the combination of countless layers of graphene with van der Waals forces, but the distance between the layers is 340pm, which is a molecular crystal, and the van der Waals force between the molecular crystals is relatively easy to destroy.

Therefore, the preparation method mastered by Lin Xuan is to start from this van der Waals force, in a specific ultra-low temperature environment, with a certain frequency of ultrasonic pulses, this van der Waals force can be directly destroyed, so that the stone grinding crystals are peeled off to form layers of graphene materials.

This method sounds simple, but the current scientific research level has not found an effective way to break this van der Waals force, even if the experimental direction is found, but at the same time meet the two necessary conditions of temperature and sound wave frequency, it is estimated that it will take several years or even longer.
