Chapter 839 Nanotechnology

Thinking of this, Zhao Zhongyao had no choice but to light a cigarette in the office, and while smoking, he was thinking about some things about how to produce nanomaterials in the world before his death.

There are many preparation methods for nanoparticles, which can be divided into physical methods and chemical methods.

Vacuum cold method: vacuum evaporation, heating, high-frequency induction and other methods are used to vaporize the raw material or form equal particles, and then quenching. It is characterized by high purity, good crystalline structure, and controllable position, but the technical equipment requirements are high.

Physical crushing method: nanoparticles are obtained by mechanical crushing, electrical spark explosion and other methods. It is characterized by simple operation and low cost, but the crystal purity is low and the distribution of grains is uneven.

Mechanical ball milling method: The ball milling method is used to control the appropriate conditions to obtain nanoparticles of pure elements, alloys or composite materials. It is characterized by simple operation and low cost, but the product purity is low and the particle distribution is uneven.

Vapor deposition: Synthesis of nanomaterials by chemical reaction of vapors of metal compounds. It is characterized by high purity and narrow particle size distribution.

Precipitation method: After adding the precipitant to the salt solution, the precipitation heat treatment is used to obtain nanomaterials.

Sol-gel method: metal compounds are solidified by solution, sol, and gel, and then nanoparticles are formed by low-depression heat treatment. It is characterized by many reaction species, uniform product particles, easy control process, and suitable for the preparation of oxides and 11-VI compounds.

Hui emulsion method: two: immiscible solvents form emulsion under the action of surface activity, and nanoparticles are obtained after nucleation, coalescence, agglomeration and heat treatment in Hui bubble. It is characterized by good monodispersion and interface, and 11-VI semiconductor nanoparticles are mostly prepared by this method.

Hydrothermal synthesis - synthesis in a fluid such as aqueous solution or steam at high temperature and pressure, and then separation and heat treatment to obtain nanoparticles. It is characterized by high purity, good dispersion and easy control of particle size.

In order to apply nanotechnology to the garment industry, it is necessary to manufacture some fabrics with nano functions.

How to make cloth with nano function. Zhao Zhongyao also knows something. He was very concerned about some high-tech things in his lifetime. He now thought of a way to make a special clothing material.

To make clothing, the first thing is to make a chemical fiber. If you want to make nano clothing, it is obvious that you can't use traditional cotton fiber. Only synthetic chemical fibers can be used.

Adding nano SiO2 and nano ZNO compound powder materials to synthetic fiber resin, which can be made into sterilization, mildew-proof, deodorizing and anti-ultraviolet radiation underwear and clothing through spinning and weaving, which can be used to manufacture antibacterial underwear and supplies, and can be prepared to meet the requirements of the national defense industry.

Zhao Zhongyao thought of a variety of methods for preparing nanoparticles. But he felt that in this world, science and technology are very backward, and some high-tech equipment is needed in the previous aspects. But it's hard to find these high-tech devices in this world. The last way is that you don't need any high-tech equipment.

Zhao Zhongyao thought about it, and could only use this hydrothermal synthesis method to produce some nanoparticles, and then use this nanoparticles to produce some nanofibers. Only in this way can you produce the nano clothing you want.

Although this is just an idea, for Zhao Zhongyao, he feels that his idea may become a reality!

After having this idea, Zhao Zhongyao felt relieved. Although, he still doesn't know how to solve the bulletproof function of the super combat suit he developed. But he felt that as long as he could solve this waterproof function first. Then there is one bulletproof function left, and it will be easier.

But it is not easy to produce this kind of chemical fiber fabric with waterproof function. Zhao Zhongyao thought about it, but he still had to discuss it with Liu Tianming. After all, this is definitely not something that Zhao Zhongyao can do alone.

At the same time, he is about to start researching now, and the first thing is to buy some experimental equipment, which requires money. Therefore, he wanted to go to the General Armament Department now and find Liu Tianming to talk about money.

After thinking of this, Zhao Zhongyao came to the General Armament Department again.

Liu Tianming's office.

"Director Liu, I'll discuss something for you. Zhao Zhongyao looked at Liu Tianming and said.

"What's the matter, is it still about your research funding? As soon as Liu Tianming saw that Zhao Zhongyao came to him again, he thought that it was very likely that Zhao Zhongyao wanted to talk about his research funding again.

"Yes, I want to buy some research equipment, so I just want you to urge the leaders to quickly allocate our research funds. ”

Zhao Zhongyao looked at Liu Tianming, and he said what he thought. After Liu Tianming heard this, he looked at Zhao Zhongyao and said, "What kind of equipment do you need, and how much does it cost?" Do you want to study your fireproof materials?"

Liu Tianming also knew that Zhao Zhongyao now wanted to study a new type of super combat suit with camouflage, fireproof, waterproof, and bulletproof, and four functions in one.

Since Zhao Zhongyao now wants to buy experimental equipment, Liu Tianming thinks about whether he still wants to study his fireproof materials!

Zhao Zhongyao listened to Liu Tianming's words, smiled and said: "It's not about studying fireproof materials, but about waterproof materials." ”

Hearing Zhao Zhongyao say this, Liu Tianming looked at Zhao Zhongyao in surprise and said, "Ah, we have to study waterproof materials." Is this waterproof material still worth researching? Isn't this a very simple thing?"

"Yes! Director Liu has some high opinions. After listening to Liu Tianming's words, Zhao Zhongyao said again. "Isn't it just waterproof material? You can use some tarp material to make your super combat suit. Tarps are not very expensive in the market! How simple is this, do you think what I said makes sense? ”

Liu Tianming feels that the waterproof function of this clothing is a very simple thing, that is, it doesn't need to be taken as a thing at all, just make a kind of tarpaulin as a raw material.

Zhao Zhongyao listened to Liu Tianming's words, then smiled again and said, "Director Liu, you think things too simply. Since I want to design a new super combat suit. Is it just an ordinary tarpaulin to be used as a raw material? This is not to fool the arms dealers, but to deceive our soldiers. ”

Hearing Zhao Zhongyao say this, Liu Tianming looked at Zhao Zhongyao puzzled and said, "You don't need a tarp, so how can you make your clothes waterproof!"

"What I want to study is a high-tech nano-garment. Such clothing is not only waterproof. At the same time, it also has the functions of anti-odor, anti-fouling, anti-infrared and anti-ultraviolet rays. It's a super high-tech garment. ”

For the first time, Zhao Zhongyao said the term 'nano' in front of Liu Tianming. After Liu Tianming heard this, he felt a little curious. It was the first time he'd ever heard someone talk about 'nano'. After all, in this world, there is no such term 'nano' yet.

Although in this world, people also recognize things at the atomic level. However, among the many physical terms, there is no such term as nano, let alone nanotechnology.

"Nano clothing, what does it mean. What do you mean by nano?"

Liu Tianming listened to Zhao Zhongyao's words and felt very curious, he didn't understand what Zhao Zhongyao meant by nano.

"A nanometer is one billionth of a meter. It is a very small unit of length. It's too small for us to imagine. Individual bacteria are not visible to the naked eye at all, and are about five microns in diameter with a microscope. Suppose a hair is 0.05 mm in diameter, and cut it axially into 50,000 strands, each of which is about one nanometer thick. Nanoscience and technology, sometimes referred to simply as nanotechnology, is the study of the properties and applications of materials with structures in the range of 1 to 100 nanometers. ”

Zhao Zhongyao looked at Liu Tianming, and didn't care if he could understand it or not, he just said these very professional words.

After Liu Tianming heard this, he looked at Zhao Zhongyao in puzzlement and said, "What do you mean, I don't understand." How do you know these things? ”

For Liu Tianming, when he listened to Zhao Zhongyao's words, he felt like listening to the book of heaven, and he didn't understand it at all.

Although Liu Tianming is also a military industry leader, he is not an expert in the military industry, and he does not know much about military science and technology. Now, of course, he doesn't understand the high-tech expertise that Zhao Zhongyao said. Not to mention Liu Tianming, even some other senior engineers in the General Armament Department, they couldn't understand it.

"Director Liu, I am a military expert, and what I think about every day is some high-tech things. These things may or may not exist in this world. Otherwise, how can we innovate and develop? If we only use what others have created and do not create ourselves, then how can our society move forward? ”

Of course, Zhao Zhongyao would not say anything to Liu Tianming, he was reborn in this world or something like that. He doesn't care if you Liu Tianming can understand it or not, anyway, he just said something like this. For Zhao Zhongyao, it doesn't matter if you Liu Tianming can understand it or not. The important thing is that you get the money I need. In this way, things will be easier to handle in the future.

"Zhongyao, what do you mean to say, what kind of nanomaterial are you going to use to study people's new camouflage uniforms. Is it a new type of nano combat suit that you want to study?"

Although Liu Tianming didn't quite understand what kind of new technology Zhao Zhongyao's nanotechnology was, he knew that what Zhao Zhongyao wanted to study must be this kind of high-tech nano combat uniform.

"That's right, I'm going to work on this high-tech nano combat suit. As long as this kind of combat uniform is studied, it is definitely a first-class combat uniform in the world. There will be no other country whose combat uniform can be compared to ours. ”

Zhao Zhongyao can now say these words confidently. After all, the nanotechnology he wants to study is definitely very advanced in this world.

"Then the nano combat suit you are researching, does it still have the function of bulletproof! Seeing that what you said is so powerful, I think this combat suit of yours must not even be able to penetrate bullets. ”

Although Liu Tianming didn't understand what kind of technology Zhao Zhongyao said about nanotechnology, Liu Tianming felt that this kind of technology must be very powerful. In this case, the super combat suit developed with this technology must also have the function of body armor.

"Although the new nano combat suit I am researching is very powerful, for the time being, I have not studied its bulletproof function. I still need to do further research on this bulletproof function. But I know that with this high-tech nanotechnology that I am studying. Completely, it allows us to work on a new type of combat suit with bulletproof features.

But this bulletproof function is also a very troublesome thing. I'm not going to look into this for now. This function will be studied after I produce the new nano combat suit.

But in any case, it is necessary to use the nanotechnology that I am working on. This technology is the basic technology for my research on new combat uniforms. In the future, my new combat suit will add some new functions, but no matter what kind of functions are added, it may use the nanotechnology I researched. ”

Zhao Zhongyao knew that the nanotechnology he was researching was definitely an epoch-making technology. In this world, there must be a scientific storm. And in the future, he will also use this technology to make Huaguo's various military equipment and some civilian equipment develop by leaps and bounds.

In this world, nano is just a term that has not yet been coined. That is, today, Zhao Zhongyao spread this term. The first person to hear it was Liu Tianming. After that, many military experts in the General Armament Department will also hear this term.

Hearing Zhao Zhongyao say this, Liu Tianming's eyes widened in surprise, he couldn't believe that this nanotechnology researched by Zhao Zhongyao would have such an important use.

"Zhongyao, since the nanotechnology you said is so important, then we must hurry up to get this technology out! In this way, don't worry, I will tell Minister Liu what you said, and I will also tell him about this nanotechnology you said. When the time comes, he will definitely be happy after listening to it. If he's happy, he'll definitely be able to fund your research soon. ”

Liu Tianming feels that the 'nanotechnology' mentioned by Zhao Zhongyao is really a very special technology. As long as Liu Changyun also knows about this technology, he will definitely support Zhao Zhongyao to come up with this technology.

At that time, Liu Tianming said that he wanted to study the matter of funds, then Liu Changyun would definitely agree immediately and allocate the money.
