Chapter 811: nanotechnology

Chapter 839 Nanotechnology
Thinking of this, Zhao Zhongyao had to lit a cigarette in his office, smoking while thinking about how to produce nanomaterials in the world before his death.
There are many methods for preparing nanoparticles, which can be divided into physical methods and chemical methods.
Vacuum cooling method: Use vacuum evaporation, heating, high-frequency induction and other methods to vaporize the raw materials or form particles, and then quench them. It is characterized by high purity, good crystal structure and controllable position, but high technical equipment requirements.
Physical crushing method: Nano particles are obtained through mechanical crushing, electric spark explosion and other methods. It is characterized by simple operation, low cost, but low crystal purity and uneven distribution along the grain.
Mechanical ball milling method: Use ball milling method to control proper 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 method: the use of metal compound vapor chemical reaction to synthesize nanomaterials. It is characterized by high product purity and narrow particle size distribution.
Precipitation method: After the precipitant is added to the salt solution to react, the precipitation is heat-treated to obtain nanomaterials. Its characteristics are simple and easy to use, but the purity is low, and the particle radius is large, which is suitable for preparing carrier materials.
Sol-gel method: the metal compound is solidified by solution, sol, and Ning glue, and then subjected to low temperature heat treatment to generate nanoparticles. It is characterized by many reaction species, uniform product particles, easy control of the process, and suitable for the preparation of oxides and 11-VI group compounds.
Microemulsion method: Two: the immiscible solvents form an emulsion under the action of surface activity, and the microbubbles undergo nucleation, coalescence, agglomeration, and heat treatment to obtain nanoparticles. Its characteristic particles are monodisperse and have good interface properties, and 11-VI group semiconductor nanoparticles are mostly prepared by this method.
Hydrothermal synthesis method-synthesis in aqueous solution or steam and other fluids under high temperature and pressure, and then separate and heat treatment to obtain nanoparticles. It is characterized by high purity, good dispersion, and easy control of particle size.
To apply nanotechnology to the clothing industry, it is necessary to create some fabrics with nanometer functions.
How to make a nano-functional cloth. Zhao Zhongyao knew a little too. He was very concerned about some high-tech things during his lifetime. He now thought of a way to make special clothing materials.
To make clothing, the first step is to make a chemical fiber. If you want to make nano-clothing, it is obviously impossible to use traditional cotton fiber. Only synthetic chemical fibers can be used.
Adding nano-SiO2 and nano-ZNO compound powder materials to synthetic fiber resins, after spinning and weaving, can be made into underwear and clothing that are sterilized, anti-mildew, deodorized and anti-ultraviolet radiation, and can be used to make antibacterial underwear and articles , Can be produced to meet the requirements of the national defense industry anti-ultraviolet radiation functional fiber.
Zhao Zhongyao thought of many ways to prepare nanoparticles. But he feels that in this world, science and technology are very backward, and some high-tech equipment is needed to use the first several aspects. But it is difficult to find these high-tech equipment in this world. There is only the last method, and it doesn't require any high-tech equipment.
After thinking about it, Zhao Zhongyao can only use this hydrothermal synthesis method to produce some nanoparticles, and then use this kind of nanoparticles to produce some nanofibers. Only in this way can you produce the nano-clothing you want.
Although this was just an idea, for Zhao Zhongyao, he felt that this idea of ​​his own might become a reality!
With this idea, Zhao Zhongyao felt relieved. Although, he still doesn't know how to solve the bulletproof function of the super combat uniform he developed. But he felt that as long as the waterproof function can be solved first. Then there is one bulletproof function, which is easier.
But it is not an easy task to produce this kind of waterproof chemical fiber fabric. After thinking about it, Zhao Zhongyao still has to discuss with Liu Tianming. After all, this thing is definitely not something Zhao Zhongyao can do alone.
At the same time, he is about to start research now. First of all, he needs to buy some experimental equipment, which all require money. Therefore, he now wants to go to the General Armament Department as soon as possible to talk to Liu Tianming about money.
After thinking of this, Zhao Zhongyao came to the General Armament Department again.
Liu Tianming's office.
"Director Liu, let me discuss something for you." Zhao Zhongyao said while looking at Liu Tianming.
"What's the matter, is it still about your research funding?" When Liu Tianming saw that Zhao Zhongyao came to look for himself again, he thought, this is probably what Zhao Zhongyao wants to talk about his research funding. .
"Yes! I want to buy some research equipment, so I just want you to urge the leader to quickly allocate our research funds."
Zhao Zhongyao looked at Liu Tianming, and he said his thoughts. After Liu Tianming listened, he looked at Zhao Zhongyao and said, "What kind of equipment do you need and how much does it cost. Do you still need to study your fireproof materials!"
Liu Tianming also knows that Zhao Zhongyao now wants to study a new type of super combat uniform with four functions in one camouflage, fireproof, waterproof and bulletproof.
Now that Zhao Zhongyao wanted to buy experimental equipment, Liu Tianming wondered if he still wanted to study his fireproof materials!
Zhao Zhongyao listened to Liu Tianming's words and said with a smile: "It is not to study fireproof materials, but to study waterproof materials."
When Zhao Zhongyao said this, Liu Tianming looked at Zhao Zhongyao in surprise and said, "Ah, we need to study waterproof materials. Does this waterproof material still need to be studied? Isn't this a very simple thing!"
"Really! Director Liu has any ideas." After hearing Liu Tianming's words, Zhao Zhongyao said again. "Isn't it a waterproof material? You can use some tarp material to make the material of your super combat uniform. Tarp is not very expensive in the market! How simple is this? It makes no sense."
Liu Tianming feels that the waterproof function of the clothes is a simple matter, that is, it doesn't need to be regarded as the same thing, just get a kind of waterproof cloth as raw material.
After listening to Liu Tianming’s words, Zhao Zhongyao smiled again and said,
Dr. Liu, you think things are too simple. Since I want to design a new type of super combat uniform, should I use an ordinary tarp? Come as raw materials! This is not to fool the arms dealer, but to deceive our soldiers."
When Zhao Zhongyao said this, Liu Tianming looked at Zhao Zhongyao in confusion and said: "You don't need a tarp, so how can you make your clothes waterproof!"
"What I want to study is a kind of high-tech nano-clothing. This kind of clothing is not only waterproof. At the same time, it also has the functions of anti-odor, anti-fouling, anti-infrared and anti-ultraviolet. This is a super high-tech garment. ."
For the first time, Zhao Zhongyao, in front of Liu Tianming, said the term'nano'. After Liu Tianming listened, he felt a little curious. It was the first time that he heard people talk about "Nano". After all, in this world, there is no term'nano' yet.
Although in this world, people also recognize things at the atomic level. But among many physical terms, there is no such term as nano, and there is no such technology as nano.
"Nano clothing, what do you mean. What is nano?"
Liu Tianming felt very curious after hearing what Zhao Zhongyao said. He didn't understand what Zhao Zhongyao meant by Nano.
"Nano is one billionth of a meter. It is a very small unit of length. It is so small that we can't imagine it. A single bacterium is invisible to the naked eye. The diameter measured with a microscope is about five microns. Assume the diameter of a hair. It’s 0.05 mm. If it is divided into 50,000 pieces in the axial direction, the thickness of each piece is about one nanometer. In other words, one nanometer is 0.000001 mm. Nanoscience and technology, sometimes referred to as nanotechnology, is the study of the size of the structure. Properties and applications of materials in the range of 1 to 100 nanometers."
Zhao Zhongyao looked at Liu Tianming, no matter whether he understood or not, he just said these very professional words.
After Liu Tianming listened to it, he looked at Zhao Zhongyao in confusion and said: "What do you mean by this, I don't understand why. How do you know these things."
For Liu Tianming, listening to what Zhao Zhongyao said, he felt like listening to the heavenly scriptures, completely ignorant.
Although Liu Tianming is also a military industry leader, he is not a military industry expert. He didn't know much about military industry technology. Now, Zhao Zhongyao certainly doesn't understand these high-tech expertise. Not to mention Liu Tianming, even some other senior engineers in the General Armament Department could not understand them.
"Director Liu, I am a military industry expert. I think about some high-tech things every day. These things may already exist in this world, or they may not exist. Otherwise, how to innovate and develop? ! Could it be that we only use things created by others instead of ourselves, how can our society advance?"
Of course Zhao Zhongyao wouldn't say anything to Liu Tianming, he was reborn in this world. He doesn't care if Liu Tianming understands you, he just said that anyway. For Zhao Zhongyao, it doesn't matter whether you Liu Tianming can understand. The important thing is that you have to get the money I need in place. In this way, things will be easier to handle in the future.
"Zhongyao, what you mean is, what kind of nano materials are you going to use to study new human camouflage uniforms. Are you going to study new nano combat uniforms!"
Although Liu Tianming didn't quite understand what kind of new technology Zhao Zhongyao said about nanotechnology, he knew that what Zhao Zhongyao wanted to study was definitely this kind of high-tech nano combat uniform.
"Yes, what I want to study is this kind of high-tech nano combat uniform. As long as this kind of combat uniform is researched out, it is definitely the world's first-class combat uniform. There will be no combat uniforms of any country that can fight us. The service is on par."
Zhao Zhongyao can now confidently say these words. After all, the nanotechnology he wants to study is definitely very advanced in this world.
"Then the nano combat uniform you studied, is it still bulletproof? Seeing what you said is so powerful, I think your combat uniform must not be able to penetrate even bullets."
Although Liu Tianming didn't understand what kind of technology Zhao Zhongyao said nanotechnology was, Liu Tianming felt that this technology must be very powerful. In this case, the super combat uniform developed with this technology can certainly also have the function of body armor.
"Although the new type of nano combat uniform I studied is very powerful, for the time being, I have not studied its bulletproof function. I have to do further research on this bulletproof function. But I know that using the high-tech I researched The nanotechnology. Completely, the new combat uniform we are studying can be bulletproof.
But this bulletproof function is also a very troublesome thing. I will not study this for now. This function will be studied after I produce the new nano-combat uniform.
But no matter what, I need to use the nanotechnology that I am studying now. This technology is the basic technology for my research on new combat uniforms. In the future, some new functions will be added to my new combat uniform, but no matter what functions are added, it is possible to use the nanotechnology that I study. "
Zhao Zhongyao knew that the nanotechnology he studied was definitely an epoch-making technology. In this world, it must be a scientific storm. In the days to come, he will also use this technology to make China's military equipment and some civilian equipment develop by leaps and bounds.
In this world, nano is just a noun that has not yet come out. That is today, Zhao Zhongyao spread the term. The first person to hear was Liu Tianming. Afterwards, many military experts in the General Armament Department will also hear this term.
When Zhao Zhongyao said 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 you said that this kind of nanotechnology is so important, then we have to quickly get this kind of technology out! Then, you can rest assured, I will tell Minister Liu what you said, and Tell him what you said about nanotechnology. When that happens, he will be very happy after listening to it. If he is happy, he will definitely allocate research funding to you soon."
Liu Tianming feels that the ‘nanotechnology’ that Zhao Zhongyao said is really a very special technology. As long as Liu Changyun is also aware of this technology, he will definitely support Zhao Zhongyao in developing this technology.
At that time, if Liu Tianming talks about research funding, then Liu Changyun will definitely agree immediately and allocate the money.
