"Bucky Tube?"

Hu Feng was stunned for a moment, he himself was a researcher of materials, and his understanding of Baji Guan was even deeper than Lu Yi's.

Bucky tubes, also known as carbon nanotubes, are another curious structure that was discovered in the study of fullerenes in the form of carbon atoms.

Graphene is simply described as a net spread out in a single layer of hexagonal carbon atomic structure, and this net is rolled up to form a circular tube, which is a carbon nanotube.

In the past, it was not possible to do this in terms of molds or series, because the mold materials and the series materials could not stably maintain the atomic morphology of the single layer.

The finished product follows the mold, and even the mold cannot stably maintain the atomic form of a single layer, so how to make the graphene layer by layer stable and longitudinally overlapped.

But now there is no problem with the mold material replaced by carbon nanotubes, which can be flattened under 1011 MPa water pressure and can be restored to their original shape, and the unique shape and structure have given the carbon nanotubes a stable shape.

"It is not possible to make a mold, although the diameter of carbon nanotubes is small, it is also "larger" than a single layer of atoms, which is not suitable for a fixed model of single atomic layer graphene.

However, if the mold fails, it is possible to use carbon nanotubes to guide the growth of graphene.

As early as 4 years ago, the laboratory has been able to produce carbon nanotubes of macroscopic length, so as long as the problem of longitudinal precipitation and polymerization of graphene along the carbon nanotubes is overcome, to ensure that there are no impurities in the precipitation and polymerization process, and to use the curved arc of carbon nanotubes to adjust the overlap angle of the graphene precipitated and polymerized on it, then the graphene superconducting material is not a dream.

If it is really not possible, you can drill a hole in the longitudinally overlapping graphene ribbon that can be made in the laboratory with a length of 59 atoms and put it into the carbon nanotube, layer by layer, and finally the longitudinally overlapping macroscopic graphene ribbon can also be obtained. ”

A string of inspiration and data instantly erupted in Hu Feng's mind, and he took the pen with some excitement and wrote down these possible fleeting inspirations and data in his notebook in a blurry and quick manner.

The notebook turned page by page, and the movements of Hu Feng's brain and hands gradually slowed down.

This experimental idea does not involve new unknown preparation methods and material properties, the focus is on inspiration and unexpected problems, so without actual tests, Hu Feng has been sure that this method can prepare qualified graphene superconducting materials.

It's just that when he roughly calculated the cost and industrial production, his expression was suddenly stunned.

"Boss, according to the inspiration you gave, I am already sure that I can produce qualified graphene superconducting materials, but the cost and industrial production are ......."

"Graphene overlap angle problem caused by elastic recovery of carbon nanotubes?"

Looking at Hu Feng recording just now, Lu Yi barely understood a little, and combined with the idea of this experiment, he guessed roughly.

"Yes, in this experimental idea, we can grow graphene ribbons that meet the requirements along the diameter of large circular tubes and attach intermediate carbon nanotubes to the modified chemical vapor deposition method.

The superconducting overlap angle can be adjusted by adjusting the bending of the carbon nanotubes to achieve the longitudinal overlap angle of the graphene attached to it. ”

Hu Feng roughly calculated it in his notebook, and said embarrassedly: "It's just that the entire graphene superconducting material will wrap the carbon nanotubes in the middle after being generated, and the carbon nanotubes have elastic recovery, and the structure and shape of graphene are different, one is longitudinal and the other is horizontal, so the deformation of the two sides will not be synchronized."

In this way, if we do not melt the carbon nanotube, the carbon nanotube that has lost the external force effect will regain its elasticity, which will affect the overlap angle of the graphene material, resulting in the loss of superconducting properties of graphene.

If it is melted, it means that this is a one-time mold, and the carbon nanotube mold must be redone every time a superconducting graphene ribbon with a width of 1,000 nanometers is made.

According to the preparation cost of carbon nanotube wire, plus the preparation of superconducting graphene materials in this way, the cost of making a superconducting graphene material is about 20 to 30 times that of the same weight of gold, and the industrial preparation is extremely difficult. ”

20 to 30 times the cost of the same weight of gold?

Lu Yi's mind came up with the demand for the magnetic field coil outside the stellar simulator tomorrow, and his head was a little dizzy and said, "Are you sure you didn't make a mistake?" Can the cost of industrial preparation be reduced, and can the carbon nanotubes in the middle be used as the attachment ground for the growth of graphene vapor phase precipitation without carbon nanotubes in the middle? ”

If the cost is really so expensive, just replacing the external magnetic field coil on the stellar simulator of tomorrow will cost more than 10 billion yuan, which is a stellarite, and the pure gold model is not so terrifying.

"Boss, industrial preparation is difficult, the premise of this experiment is that carbon nanotubes must have a macro length, and now carbon nanotubes can only be made in the laboratory, and industrial preparation can not meet the requirements, so this is why the cost is so high."

Hu Feng thought for a while in his mind, and continued to say regretfully: "In addition, it is not possible to remove the carbon nanotubes in the middle, the carbon nanotubes are too thin, and the size of the nanometer can barely be achieved by changing the bending amplitude of a carbon nanotube to achieve the longitudinal overlap angle of graphene, and the large round tube formed by multiple carbon nanotubes on the periphery wants to achieve the bending amplitude synchronously, which is beyond the scope of current technology."

The function of the outer carbon nanotubes to form large circular tubes is mainly to standardize the macroscopic neat specifications of the constrained graphene nanoribbons, rather than to control the growth overlap angle of the graphene nanoribbons. ”

The commercialization of science and technology is not only a matter of materials, but also the requirements of industrial precision, the requirements of the electronic information industry, etc., which is a comprehensive problem.

If we really want to be clear, the level of science and technology in the world's laboratories is at least 20 years old in the military market and more than 30 years in the commercial market.

"it!"

Lu Yi didn't know how long it had been since he had a foul mouth, and the cost of replacing the coil of a single stellar simulator would be tens of billions, even if he was used to it during this time, he felt that his heart was a little unbearable.

Taking a deep breath, Lu Yi said helplessly: "Brother Hu, you first prepare a superconducting graphene wire, and then talk about the next step after testing the actual superconducting performance and cost of this material." ”

He didn't talk about adding the macroscopic length of the industrial preparation of carbon nanotubes to the research sequence, this thing is not so simple, if it is really so easy to get, the large launch vehicle has long been bankrupt and eliminated, and the major powers of the space elevator have already begun to build projects, instead of still holding it in their minds, trapped in the laboratory and unable to get out.

Compared with the space elevator, it is more important to control the nuclear fusion change, at least this project is completed, unless there is a large-scale war to destroy everything, there is no worry about extinction.

"Yes."

Hu Feng nodded, beckoned the researchers in the laboratory to start decomposing the task and devoting themselves to the preparation of the first superconducting graphene wire.
