"Although multi-stage flash evaporation technology is relatively mature, compared with reverse osmosis, it has two obvious disadvantages.

First, multi-stage flash evaporation requires the waste heat of thermal power plants. Otherwise, the cost is not much cheaper than distillation, so the natural limitation is relatively dead;

Second, based on cost, it was previously equally divided with reverse osmosis method, but after Liu Feng developed several new polyamide composite materials, the cost was significantly higher.

Therefore, I think the focus of research on seawater desalination is still on reverse osmosis membrane materials.”

I have to say that even academic literature is reasonable and well-founded.

However, since it is a discussion, there are definitely objections.

However, this time, it was not Professor Wang Shichang who opposed it, but another professor who was involved in multi-level flash evaporation technology, Wang Xiaodong, and the other party was also well-founded.

"You are right. Multi-stage flash evaporation technology does have these two disadvantages at present. For the first point, for our country, it is an advantage. After all, my country's thermal power stations account for more than half of the country's power generation, so the waste heat problem is completely surplus.

As for the cost, multi-stage flash evaporation is a little higher than polyamide materials, but in my opinion, this is only temporary. This problem can be solved in repeated experiments, and there are routes and clues. Compared with polyamide reverse osmosis materials, it is basically a dead end. Isn’t it clear who has greater potential? After all, even Professor Liu Feng and Liu may find it difficult to make a major breakthrough in polyamide composite materials?

Professor Liu Feng, what do you think?"

Liu Feng:…?

Professor Liu?

When did we become professors?

This expert is really good at speaking!

Liu Feng, who didn't want to intervene in the fight between the big shots, sat there and didn't say anything, but inexplicably got an arrow in his knee.

But, is it because you look down on me so much that Tai Bai Jinxing gives you the courage?

The meeting was held with a little snack and could hear the open and secret arrows in the words, not to mention that the people on both sides had been fighting for a long time.

Therefore, Liu Feng, who was sitting in the front row, could only sigh and stood up.

Sure enough, my colleagues are enemies. Fortunately, the superpowers that control the microscopic world saved him most of the R&D costs, and the patent authorization of polyamide materials was also sold at a good price; otherwise, at this moment, he would not even be qualified to join this battle.

In my heart, I said embarrassed to the expert Wang who just called him Professor Liu: "Actually, this expert is right. In terms of polyamide composite materials, I think it is indeed difficult to make a significant breakthrough; however, I still agree to focus on the research and development of seawater desalination on the research of reverse osmosis membrane materials!"

Liu Feng always thought that he was a straight person and said whatever he had. He would never go around the bush, let alone talk a lot of things, but he ended up talking nonsense.

He was never afraid of offending people.

Playing politics with a group of stingy foxes is completely about attacking the enemy's strengths by just one's own shortcomings, not a wise thing to do.

Therefore, the big guys will fight for research funds. Anyway, he does not lack money in experiments, and offends people. If you have the will of you, you can bite me.

When the first half of Liu Feng said, the expert Wang Xiaodong still had a smile on his face, but when the second half of him heard, the expert Wang raised his eyebrows obviously.

"Oh? In the field of seawater desalination, who doesn't know that the main direction of reverse osmosis membrane materials is polyamide. Since Professor Liu is not sure of making breakthrough progress, why not put the limited funds on the topic of clear research routes? Could it be that Professor Liu's research routes for reverse osmosis membrane materials have made new discoveries?"

Although this expert Wang is engaged in multi-level flash steaming, Liu Feng still has to praise you, you always have to be in Cao’s camp and your heart is in the Han Dynasty!

It’s such a magical assist. How come you always know that I have made new discoveries!

Liu Feng sighed.

With a low-key attitude, he didn't want to show off his unfinished research results, but now he has nothing to do.

If he is used by someone who is interested in the future, he says that he only cares about his own interests and takes advantage of the situation, but conceals the latest research technology on national projects and wastes national resources. This is not good.

After thinking for a moment, he spoke.

"It's not impossible for you to say that. Although I haven't studied the new achievements yet, when it comes to research, I personally prefer the polycarbon structure direction similar to graphene structure."

After Liu Feng said this, except for Mr. Zhou, Zhang SHU Ji and Principal Tan, the people present were basically stunned.

Are there really new discoveries?

In the conference room, experts and professors had different expressions.

Some were disdainful, some were unquestionable, and some were surprised and happy, looking forward to Liu Feng continuing to talk.

Especially the expert Wang Xiaodong, obviously did not expect that Liu Feng actually had a research route, and he was willing to share it with everyone! As for Mr. Zhou, Zhang SHU Ji and Principal Tan, he had an expression that he had known for a long time.

Liu Feng paused for a moment and continued: "Everyone knows that graphene is a two-dimensional carbon nanomaterial composed of carbon atoms and a hexagonal hybrid orbital with a honeycomb lattice. In a water environment, after graphene is intimately in contact with water, it can form a channel about 0.9 nanometers wide. Ions or molecules smaller than this size can pass quickly. If we can further compress the capillary channel size in the graphene film and control the pore size, we can efficiently filter the salt in seawater."

As soon as Liu Feng finished speaking, Professor Wu Qingquan from Shuimu said, "I have a problem."

Liu Feng: "Professor Wu, please speak."

Professor Wu said slowly: "Graphene is a very new and popular conceptual material. It has been researched in the laboratory, but it is difficult to form large-scale industrial production. Therefore, the price of this material, when used in seawater desalination, is definitely a waste of material and is not worth the cost."

Liu Feng explained: "Of course, graphene and even other carbon sphere materials similar to graphene are often limited by price factors, but with the development of technology, these materials may not be unable to achieve industrial production and reach the bargain price."

Wu Qingquan shook his head and looked sharp: "What you said is indeed possible, but within at least 20 years, it is absolutely impossible to form large-scale industrial production of graphene with reasonable prices! The problem now is that our funds are limited. If we use it for such a large-scale money-consuming enterprise, will other research be done?"

Professor Wu is also an interesting person. His own research direction is unpopular, but at the beginning the funding was similar to other directions. Therefore, a few years have passed, and there is still a large amount of funds allocated.

If it were someone else, I would have probably made a name and went to an unknown place. He had already returned some of the money.

There are probably not many "fools" like this in this era!
