A newly developed material can make the cracked mobile phone screen a past.
Source: supplier scientists have developed a new material that can solve one of the most annoying problems faced by smartphone users.
This material is transparent, highly stretchable, conductive, and most importantly, self-containedhealing.
It fixes itself when it breaks or tears.
Created by chemists at the University of California Riverside and the University of Colorado, it may have a lot of uses in robotics and consumer electronics, and it may end up making your cracked iPhone screen a thing of the past.
\"It has been a difficult problem for years to make a material with all these properties,\" Wang Chao, a leading researcher, said in a statement.
\"We did that and it\'s only now that we\'re starting to explore the app.
\"Perhaps because of their prevalence, some people even think that a broken screen on the phone is an identity symbol --
Prove the height of a personpaced life.
But for those of us who do not want to prove our social mobility by destroying our things, such material may be a godsend.
In an interview with the Science Daily, Dr. Wang said that the team conducted some experiments on the self-repair ability of this material.
In one example, after being torn in half, it will automatically re-stitch together in less than 24 hours.
According to his university, Dr. Wang became interested in himself.
Healing material, because he loves the comic character Wolverine all his life, he has the ability to self-heal.
\"He can save the world, but only because he can heal himself. A self-
\"When the healing material is carved into two parts, it can go back together as if nothing had happened, just like our human skin,\" he said . \".
\"I have been working on being a self.
Treat lithium-ion batteries, so it can be self-fixed for longer periods of time when you drop your phone. ”The low-
High cost, easy to produce soft rubber
Materials like this can be stretched 50 times the original length.
Dr. Wang believes that this material will be used \"soon\" for the manufacture of mobile phones.
Because this material can conduct electricity, it can be used to provide scratch-resistant and very durable smartphone screens.
This material can make the cracked screen of the phone a past.
How did they develop it?
The study was published in the journal Advanced Materials as early as December, but since the research team presented their work at a meeting of the American Chemical Society on Tuesday, it has received wide attention.
The secret to developing this material is to produce a tolerant chemical bond between molecules, which is stable under the condition of an electrochemical.
Dr. Wang explained that basically, there are two types of bonds in the material.
These are the price keys. they are very strong. once they are broken, they will not be changed.
Bonded bonds are more energetic, for example, the hydrogen atom that connects water molecules to each other is very energetic.
Fluid properties of water.
However, a material made of a substance with such a bond is not suitable for ion conductors (
Necessary for use in electronic products)
Because they are affected by the electrochemical reaction that reduces the performance.
The team uses an ion-
Electric two-pole interaction, that is, the force between charged ions and polar molecules.
The university says it is very stable under the conditions of electrochemistry.
By moving the stretchable polymer with a highionic-
Power salt, researchers are able to create the attributes they want.
