Created “wooden glass”

While some scientists are struggling to create flexible matrices and glass, others are looking for alternative materials that can be used to create components for smartphones. For example, wood, which can replace the ordinary glass. And it's not about the rear wooden covers.

Scientists from the University of Maryland and the University of Colorado in the United States have created a “transparent tree.” They took a layer of balsa wood as a starting material and immersed it in an oxidizing bath. This made it possible to make it practically transparent and then it is covered with a synthetic polymer (polyvinyl alcohol) to give it the necessary transparency and rigidity.

In addition to environmental friendliness, the resulting material is stronger and lighter than traditional glass. And another important feature of it is that it bends. And that makes “transparent wood” a material that can be used in smartphones with flexible displays. The authors of the invention claim that “wooden glass” is more impact-resistant and more reliable than ordinary glass, and its mass production does not require large expenditures.

At this stage, the creators of “transparent wood” are working to bring the material and the technology of its creation to perfection. In the long term, it should replace conventional glass in eco-houses and cars. But it may not reach smartphones soon.

But scientists from the University of Maryland and the University of Colorado in the United States are not the first to come up with the idea of discoloring the wood. Back in 2016, engineers from the Swedish Institute of Technology presented the first sample of the “transparent wood”. But its serial production never began.
