New glass Anti-break phone screens

Many smart phone users around the world suffer from a recurring problem of dropping their phones from their hands, which causes scratches and breaks in the phone screens, and repairing them is often expensive, but scientists have finally put an end to this phenomenon by designing a new type of glass that is more Five times more shatter-resistant than standard glass, it can finally put an end to shattered phone screens.Join Our Telegram group to know the latest news

The glass-acrylic composite material, which “provides a combination of strength, durability and transparency”, was designed by researchers at McGill University in Montreal, Canada.

The researchers drew inspiration from the stronger and tougher glass from the inner layer of mollusk shells, called nacre, also known as mother of pearl, which resembles a wall of interlocking Lego bricks at a microscopic level.

The researchers reported that despite being glass, the new material has a flexibility that is very similar to plastic and does not shatter on impact.

If mass-produced and put on the market, it can be used to put an end to high-end smartphones that fail from a simple fall to the ground.

The shells of mollusks are composed of about 95% chalk, which is very brittle in its pure form.

But the seashells, which cover the inner shells, are made of microscopic discs that look a bit like little Lego building blocks, which makes them so strong. It is also very flexible, allowing the shell to resist impact without breaking.

“Surprisingly, nacre has the toughness of a hard material and the durability of a soft material,” said Allen Ehrlicher, associate professor in McGill University’s Department of Bioengineering. “It’s made of solid pieces of chalk-like material coated with soft, highly resilient proteins. This structure produces exceptional strength, which makes it extremely strong.” “3,000 times stronger than the materials it’s made of. Nature is the master of design, and studying the structure of biological materials and understanding how they work provides the inspiration, and sometimes blueprints, for new materials.”

While techniques such as tempering and lamination can help strengthen the standard glass in today’s phones, they are expensive and no longer work once the surface is damaged.”

“Our new material is not only three times stronger than ordinary glass, but more than five times more resistant to breaking,” he explained.

The nacre is made of hexagonal or square sheets of aragonite (a form of calcium carbonate), arranged a bit like a brick wall.

Scientists took engineering the nacre and copied it with layers of glass and acrylic foil, resulting in an “extremely strong” opaque material that could be easily and inexpensively produced.

They then went so far as to make the compound optically transparent, by changing the refractive index of the acrylic.

The refractive index indicates how the speed of light changes as it moves between different media.

The team’s next steps are to improve unbreakable glass by incorporating smart technology that allows glass to change its properties, such as color, mechanics and conductivity.

In their paper published in Science, the team wrote: “Glass has many applications due to its exceptional transparency and hardness. However, its poor fracture, impact resistance and mechanical reliability limit its range of applications. The manufacturing method is robust and scalable, and the compound may prove to be an alternative to glass in a variety of applications. “
