Tang Yan didn't know what Wei Wei was thinking, so he didn't have any reservations about what he did at night.

Vivi opened her mouth wide after listening.

How could she have forgotten that the main god system has all kinds of materials from the future!

Mistake, mistake!

Weiwei cautiously asked, "Then will your project be completed soon?" ”

"Not so fast." Tang Yan was a little frustrated, "There are too many places that need to be experimented, and it is much more difficult than I imagined." But having the data is definitely much faster than not having the data, and if there is no data, I may not be able to do it in 10 or 20 years. ”

She booked a hotel for a week, thinking that she would be able to finish her thesis in a week. However, the work of studying physical materials is much more complicated than the technical flow of lithography machines, and I am afraid that it will take about 10 days.

Vivi patted her chest reassuringly.

She was misled by Tang Yan's 10 years and 20 years of time, and not so quickly summarized, and thought that the project also needed to be calculated in years.

She swallowed all the bread in her mouth and waved her little hand heroically.

"Let's go! I'll accompany you to the experiment! ”

……

Tang Yan took the note approved by Zhao Xifu and came to the laboratory, and as soon as he pushed the door open, he saw Gao Jiang inside.

The coolies came early!

Tang Yan immediately showed a hypocritical smile, took out the free bread and milk provided by the hotel, handed it to Gao Jiang, and greeted him enthusiastically.

"Morning!"

Gao Jiang looked at the bread and milk in his hand, and his mood was extremely complicated.

When he chased girls before, he didn't give breakfast to girls.

But this time, not only did I forget it all, but I was also given breakfast by a girl.

But so what?

Gao Jiang unceremoniously took the bread and milk and ate it.

Tang Yan is no longer a primary school girl, but a team leader!

What's so unusual for the group leader to bring breakfast to a group member like him who works as a coolie!

Gao Jiang had already accepted his fate in his heart, and set a position for himself very clearly.

Waiting for Gao Jiang to finish breakfast, Tang Yan stretched out his hand unceremoniously.

"What about your previous experimental data and stage results?"

Gao Jiang can be a doctor under the academician, although he looks a little stupid, but he is indeed not an ordinary person.

In just one night, he sorted out all the data and directly handed over the USB flash drive to Tang Yan.

Tang Yan opened the laptop he brought, plugged in the USB flash drive, and took a closer look.

I couldn't help but be a little surprised at this look.

The original team's experimental direction turned out to be right!?

Using the "directional deformation assembly" method, high-performance materials with bionic structures were developed.

Although both experiments and theories are in the intermediate stage, as long as they are not disbanded and persisted, sooner or later they can make "second-generation plastics".

The "second-generation plastic" is a high-performance sustainable structural material with a biomimetic structure by combining cellulose nanofibers and titanium dioxide-coated mica sheets.

Its mechanical and thermal properties are better than those of the original plastic.

It's just that because the cost is higher than real plastic, there is still a lot to be improved.

Tang Yan shook his head with some pity.

As long as the funds are sufficient, the original team will be able to produce results in another year or two, which is a pity!

And in Tang Yan's view, the plastic used now seems to be low-cost, but it does not consider the cost of environmental protection.

Considering the cost of processing plastics, it is definitely higher than the cost of "second-generation plastics".

But the market of capital cannot tolerate Tang Yan's naïve and idealistic idea.

If you want to truly replace plastic, it will be widely promoted. The production cost of new products should be at least the same as that of real plastic.

Even flat is not enough.

Because it takes a process for everyone to accept new things, and it takes money for factories to buy new equipment. The cost of materials may be the same, but the upfront cost is high, which will make it difficult to promote.

Although it has nothing to do with Tang Yan whether it is difficult to promote, she just needs to research new materials to replace plastics. Even if it is to make "second-generation plastics" according to the original team's ideas, it is a great achievement.

Not to mention the thesis of a graduate student, the thesis of a doctoral degree is weighty.

But even though Tang Yan has lived in the small world for many years, he is still the hot-blooded young man who is less than 20 years old in his heart, full of idealized ideas.

Plastic is difficult to degrade after discarding, and it is a big problem to continuously cause environmental pollution.

Just having this opportunity, Tang Yan is willing to solve this problem directly, rather than doing a perfunctory job for graduation.

She carefully analyzed the "three generations of plastics" and "four generations of plastics" in the materials provided by the main god system.

The technical difficulty of the third generation is lower than that of the fourth generation, and the performance is better than that of the original plastic, and it still cannot be degraded when buried in the soil.

However, it can be destroyed by incineration, and it will not produce any harmful gases, which is absolutely environmentally friendly. In the era of three generations of large-scale use of plastics, there are specialized robots responsible for collecting and destroying waste plastics.

But now, it can only rely on labor, and the specific cost needs to be accounted for by Tang Yan.

By the time of the four generations of plastics, times had changed dramatically.

Due to technological advances, the division of materials is more detailed. The vast majority of plastic products are replaced by other better materials.

The so-called fourth-generation plastic, which only specializes in ductility and thermal properties, is used to make plastic bags.

Not to mention the technical difficulty, it can only solve the environmental protection problem of plastic bags. For other plastic products, other plastics also need to be developed.

However, the advantage is that there is no need to collect and incinerate it, and it can be degraded as long as it is buried in the soil for one year, which greatly reduces the cost of subsequent treatment.

It's just that since this thing can be degraded by the land, it proves that the performance is not as stable as the original plastic. If you leave it at home for about 10 years and don't take good care of it, plastic can become fragile.

The reason why the fourth generation of plastic will be widely promoted is because it has entered the interstellar age at that time, and people have space equipment.

The fourth-generation plastic is only used temporarily, or the garbage cleaned up by housekeeping robots, regardless of the length of use.

Tang Yan's brows furrowed.

Both of these plastic alternatives have their advantages.

There is no processing cost for four generations, and the cost will definitely be much lower. However, the technology is difficult and cannot completely replace the current plastic.

Three generations can perfectly replace the current plastic, but it needs to be disposed of. If it is not disposed of, it is no different from today's plastics in terms of environmental friendliness.

Coupled with this part of the processing cost, I don't know if there is a price advantage for the three generations of plastics?

Without a price advantage, it is extremely difficult to promote.

For the first time, Tang Yan deeply understood that not all future technologies can perfectly adapt to the current era.

Many times the steps are too big, but they can't adapt to everything that is now packaged.

Although he encountered difficulties, Tang Yan was not a person who flinched easily.

The first step at the beginning of the project is to calculate the cost.

Gao Jiang provided that the data studied by the original team included the current cost of producing plastic products, which saved Tang Yan a lot of trouble.

So now what Tang Yan and Gao Jiang have to do is to visit various garbage dumps to see how much it costs to collect and incinerate plastic products!
