Hand rubbing nuclear fusion live in the wilderness

Chapter 204 Research and Development Materials
In his mind, a faint idea rose up, but it was deeply rooted in Han Yuan's heart like a seed.

The charcoal pencil in his hand was firmly grasped, and the paper was spread on the table, but what was recorded was no longer the original thing.

After thinking for a while, Han Yuan took the lead in writing the properties of transparent electrodes and his own demand for new materials on paper.

If you want to develop a new material, the first step is naturally the demand. With a clear demand, the research and development personnel can carry out research and development according to the demand.

Transparent electrodes are the core materials of transparent displays.

In visible light sources visible to the naked eye, it is required to have high light transmittance and high conductivity at the same time.

If described by quantitative indicators, at 550 nanometers, the visible light source transmittance of the material is above 80%, the surface impedance is below 1000Ω/sq, or the conductivity meets 1000S/m.

Based on this, Han Yuan took the lead in excluding indium, gallium, molybdenum and other rare metal compound materials because he did not have them.

The next thing to exclude is graphene. Although graphene can also be used to make transparent electrodes, he can't get it out for the time being.

The second is a polymer carbon material with the same properties as graphene. This is the same as graphene, and he can't get it out for the time being.

After eliminating the unusable materials, Han Yuan thought for a while, arranged the high crystal glass and transparent plastic, and wrote on the draft paper.

In the case that the single material cannot be satisfied, the use of high-crystalline glass and high-transparency plastics for front and back coating may be an available method.

Whether it is high crystal glass or transparent plastic, it has strong light transmission, but it is not conductive.

So this requires that the coating must have a little conductivity.

Moreover, high-crystalline glass and high-transparency plastic each have their own advantages and disadvantages.

High-crystalline glass is durable, easy to coat, and has good light transmission. High-transparency plastics have the flexibility that high-crystalline glass does not have, and can be curled to a certain extent.

As for conductive materials, he has a lot of them. Apart from metals that can conduct electricity, there are also many polymer materials that can be used.

For coating, Won thought about it and wrote down the words 'reactive ion plating' and 'electroplating process'.

The principle is the same as the last time he used osmotic hair to make the N-drift layer, and hydrochloric acid solution or sulfuric acid solution can be used as the electrolyte.

It only needs to plate a thin layer on the high crystal glass or plastic substrate to achieve the conductive effect.

However, the coating used on liquid crystal displays not only requires high light transmission and conductivity, but also requires the ability of transparent electrodes to have the ability to conduct electricity and arrange electrons in combination.

Because it is necessary to rely on the transparent electrode to generate an electric field to drive the liquid crystal molecules, resulting in a twisted nematic electric field effect.

In this way, the transmission or shading function of the light source can be controlled, and the light and shade effect can be generated at the same time as the power is turned on and off, so that the required image can be displayed.

This is the key point, it can be said that more than [-]% of the metal has been directly stuck.

Metals like copper and iron are stuck directly outside the wall.

"What about metal oxides or polymer materials?"

Looking at the information written on the paper, Han Yuan pondered silently for a while, considering whether these two materials are feasible.

Not to mention the conductivity of metal oxides, polymer compounds such as polyaniline, polythiophene, and polypyrrole are also conductive, and the conductivity is not even weaker than that of ordinary metals.

It is possible to use the coating for transparent electrodes, but what about the specific performance, maybe it needs to be tested again?
After thinking about it, Han Yuan searched out these polymer materials from the primary chemical application knowledge information, and then carefully checked the characteristics and applications of these materials.

It would be very troublesome for him to experiment one by one.

Fortunately, the corresponding knowledge information in his mind can give him some help, at least allowing him to eliminate some inappropriate ones, which can effectively reduce the workload.

In the studio, the lights were bright, it was already two o'clock in the morning, and a figure was still prostrate at the desk, writing and drawing something.

While writing and drawing, he kept talking to himself and murmuring some inaudible words.

Sometimes the tone of voice is slightly higher, and the two jaguars who are sleeping aside will look up suspiciously.

After more than half an hour, Han Yuan stopped writing.

Although it was late at night, Han Yuan didn't feel sleepy looking at the messy draft paper on the table, his eyes were bright and energetic, and his whole body was as excited as if he had been injected with chicken blood.

In a few hours, through my own thinking, I developed a brand new material, and I gained a little. The sense of accomplishment gained in the process is really satisfying and exciting.

"Aluminum-doped zinc oxide, polymer polypyrrole compound."

These two materials were selected from many pre-selected materials when he was busy for several hours.

One is a metal oxide, and the other is a polymer compound, both of which have extremely strong electrical conductivity.

More importantly, these two materials can form a transformed electric field by driving the IC to input combined current after plating, so as to realize the manipulation of liquid crystal.

Looking at the data and information on the draft paper, Han Yuan had a satisfied smile on his face.

This is the first time he has expanded on the knowledge in his head to develop a completely new material.

Although a lot of knowledge information provided by the system was used in the research and development process, the inspiration for expansion and the basis for research and development were his own.

After checking the information recorded on the draft paper, Han Yuan copied the preparation methods and plating methods of the two different materials onto brand new paper, and then rolled it up.

Now just wait for tomorrow to conduct experiments to verify his results.

Although success or failure is important, the most important thing is that this is the first step for him to develop his own products, breaking his previous barriers of completely relying on the system.

It was the first time to design a brand new material, which made Han Yuan a little over-excited, and he closed his eyes and went to sleep until three o'clock in the morning.

When I woke up, it was only light outside, and it was around seven o'clock.

He only slept for about four hours, but his whole body was very energetic, and he didn't feel tired from lack of sleep at all.

After washing up and having breakfast as usual, Won started the live broadcast.

The audience poured in and asked about the content of today's live broadcast.

Han Yuan smiled, turned around and came to the workshop, took out the drawings and draft paper of the new materials he developed last night, spread them on the table and showed them in the live broadcast.

"Aren't you all very interested in why I suddenly changed the content of the live broadcast a few days ago?"

"The answer is on the drawing."

"Before this, I was going to use 'ray display tubes' to make displays."

"But later, due to some accidents, I found that the display made by the 'ray display tube' could not meet the requirements."

"So, I redesigned a whole new monitor."

"In the past few days, I have been drawing and writing drawings, designing and planning the materials and core parts needed for the new display."

"And last night, the work was completely complete."
