What would you do with the most slippery material in the world?

 What would you do with the most slippery material in the world? 


"Researchers have made groundbreaking discoveries in superlubricity, demonstrating how this state of minimal friction could revolutionize energy efficiency in mechanical systems. Their work reveals that friction in superlubricity defies traditional laws, offering promising applications for reducing global energy consumption.

While people talk about slippery materials they don't think about what makes material slippery. The thing that makes materials slippery is one thing that determines the use of materials. People can use Slippery materials, like slippery polymers for transporting heavy things, like furniture at least for short distances. 

In those cases, the ideal material can be a polymer shell that is slippery when it's against another polymer. That thing decreases friction. In those cases, the polymer has a slight layer. And that thing makes that polymer friction very low. 

In some versions, there are small "hair" or strings on the polymer layer. When a person moves things another way, those strings will pull into the holes that are on that layer. But when the merchandise moves to another side, that pulls those strings up. That increases the friction and prevents the object slide backward. 

In some models, those nano-wires can pulled in when electricity is conducted in that material. That thing makes it slippery when the user wants it. That ability makes those systems keep strong in touch with gloves. And when the electricity is conducted to that material, it removes dirt from the layer. 

In some cases. There is a liquid polymer that the user can pour into the layer. There are small nano-balls that are on slight polymer. Those nanoballs can make the layer extremely slippery.

But there is another way to make the shell slippery. In some versions, small grooves on the shell decrease friction. Those grooves' diameter is so small, that things like water will not enter the bottom of them. The surface tension keeps water out from the bottom of those grooves. That thing minimizes the contact layer. 

The small grooves on the Northrop X-21 test plane wings decreased its use of fuel and increased its flight time and operational range. In the same way, the fastest sailboats have small grooves on their hull. That decreases friction and increases speed. Those small grooves can also decrease fuel use in ships. 

That kind of material can used in ships and submarines to minimize friction. But in some versions, the slippery material is covered using nano-rolls. Those nanorolls rotate when something rubs the layer. Engineers can cover things like aircraft or submarines with nano rolls. That is connected to generators which makes them more energy-effective than using normal material. 

In that case, the system can recycle part of the energy. That it uses. This kind of system can also deliver electricity for nanotechnical sensors, whose purpose is to warn submarines about the threats.

Superhydrophobic materials can be more fundamental than we think.

"Research on metal-organic frameworks has led to the development of superhydrophobic surfaces by grafting hydrocarbon chains, which cre...
