North of Jakarta, as far as the eye can see, the offshore is full of freighters, horns blaring, tourists, workers and trucks.

To the southwest, the port is lined with rows of secure warehouses with white facades, reserved for offshore companies to lease.

It is one of the few gray areas in Jakarta where officials turn a blind eye...... As long as you don't do anything excessive here, the Indonesian authorities will not care about it under normal circumstances.

In the middle part of the warehouse area, there is a closed dust-free warehouse covering an area of more than two acres and nearly 20 meters high.

Jiang Bo, who was wearing a dust-free suit, thought about it and took out the 13 tons of graphene from the inventory.

There was no clanging sound, no other movement, and as soon as my eyes closed and opened, a small mountain of containers appeared in my sight.

Accustomed to this kind of scene, Jiang Bo clapped his hands calmly, stepped forward, and opened a container to reveal a PET material on the bottom of the ice.

Reaching out and scooping it up, I took this material in my hand, and I felt that it was light and cool, and the texture was very weak.

The fingers were twisted, and the material, which was originally only about 1.5 square meters, quickly unfolded, and after five more reciprocating times, it became a transparent film of hundreds of square meters.

On top of this 100-square-meter film, there is also a thinner graphene with a mass of only 38 milligrams.

It is worth mentioning that the single-layer graphene, unlike the double-layer, the single-layer graphene material is relatively soft, and if it is not the touch caused by the electronic interaction between the skin and the graphene surface in the palm of the hand, it is almost impossible to feel its existence, because it is too light and soft.

"Technology is really amazing, PET film weighing only a few grams on one side can be extended to hundreds of square meters, and graphene film on one side of hundreds of square meters is only a few tens of milligrams...... The technology of ruins in this area is decades ahead of the earth. ”

After some tinkering in the warehouse, Jiang Bo patiently cut the 100 square meters of graphene into 100 copies with the instruments and equipment purchased by Jian Pengfei, and then sealed it with PET materials bought locally in Jakarta, and quickly packaged it into 100 copies, and finally transferred it into a suitcase together.

Leaving the warehouse with a suitcase, Jiang Bo came to the offshore company that Jian Pengfei had acquired, the St. Regis Trading Company.

As soon as he met Jian Pengfei, he said that a buyer had come.

"Boss, just now a domestic company called our customer service center, saying that it has arrived in Jakarta and wants to make an appointment to see the goods, if appropriate, it will purchase a batch of graphene. ”

Jiang Bo smiled slightly: "It seems that there are already fish taking the bait, this should be the first company to come to Jakarta, right?"

"yes, do you want to meet them today, or do you?"

"I'm sure I'm going to see them, but I'm not going to show up. Jiang Bo handed the suitcase to Jian Pengfei and said: "There are a hundred copies of 1mX1m size single-layer graphene here, if you want to see the goods, then you can take a few copies to show them, real gold is not afraid of fire refining, let them test it quickly." ”

"Okay!"

"Go ahead, I'm not good at negotiating, I still have to get you out. ”

……

Jakarta Hatta Airport.

After Meng Nanfeng and Zhang Li and a group of eight people got off the plane, they hurriedly walked outside the airport.

Zhang Li is the general manager of Shenzhen Keyuan, a high-tech company specializing in carbon nano-products, including but not limited to carbon nanotubes and graphene.

For example, Keyuan Company is currently doing the more cutting-edge graphene thermal conductive film, graphene high-efficiency batteries, graphene soft electronic screens and graphene body armor on the market.

Meng Nanfeng is the deputy director and academician of the Institute of Micro and Nano of the Chinese Academy of Sciences in Shenzhen, and is also the technical consultant of Keyuan Company, engaged in research on micro and nano technology for decades.

In addition to carbon nano things, he has also made other two-dimensional nano products.

For example, two-dimensional semiconductors, transition metals, dichalcogenides, black phosphorus, etc., as well as the best known two-dimensional insulator, hexagonal boron nitride.

This time, the purpose of the two of them coming to Jakarta was not to buy any meter-level single-layer graphene, but to use this reason to come to Jakarta to see a carbon nano engineering laboratory invested and built by Keyuan Company.

The reason for the purchase of graphene is that in order to attract buyers to come to Jakarta to see the goods, St. Regis specially said that the expenses of less than one million yuan can be reimbursed by them.

Thinking that the company's development was not easy, Zhang Li did it.

To put it bluntly, it is cheap and not a bastard, but if this St. Regis company really has a large number of meter-level graphene monocrystalline wafers, then Keyuan Company will not hurt even if it buys a batch.

But if not, then I'm sorry, this small advantage is taken, and St. Regis can't say anything.

Meng Nanfeng asked, "Mr. Zhang, should we go to the laboratory first, or do we really want to go to the St. Regis company?"

Zhang Li smiled: "Of course, you have to go to St. Regis first, Academician Meng, I'm afraid you have to trouble you to go with us, you are an expert in the screening and detection of graphene wafers." ”

Meng Nanfeng waved his hand: "Mr. Zhang is polite, since he has taken up a position in the company, these are all things within his bounds, but ...... Some truths, whether you like to hear it or not, Mr. Zhang, I have to mention it.

Graphene, since it came out, we have begun to do it, and the progress is not lagging behind the United States, Germany and other developed Western countries, basically it can be said that the graphene they can make can be made, we can also make it.

But after all, it is a two-dimensional material, and if graphene wants to be mass-produced, with the current technological height of the industry, there is no sign of it.

The annual output of a single device does not exceed 10 grams of companies affiliated with the Graphene Research Institute in Yanjing, so it is unlikely that the words released by the St. Regis Company in Jakarta are true.

In this regard, I think Mr. Zhang, you should have a plan in your own heart, don't expect too much. ”

Graphene is a good thing, there's no doubt about that, no, to be precise, any material that can be two-dimensional, is a good thing.

Because the rise of 2D materials opens up huge possibilities for potential applications in electronics, optoelectronics, and photovoltaics, after all, they are smaller in size, higher in speed, and newer in functionality.

The preparation of large-area, high-quality basic two-dimensional single crystal materials is the core of the large-scale application of two-dimensional devices.

However, due to technical and equipment problems, no two-dimensional material can achieve real mass production, even if Keyuan Company is only a marginal product, and it is far from reaching the point of entering its core.
