In a surprising twist in the world of technology, researchers are diving into the possibility of swapping out traditional glass and plastic smartphone screens for something a bit more natural – wood.
Yep, you read that right – wood! Scientists at the KTH Royal Institute of Technology in Sweden and the University of Maryland are tinkering with the idea of transparent wood as a potential game-changer in display technology.
Now, you’re probably wondering how in the world wood can be see-through. It turns out, it involves a bit of science magic. They mess around with this stuff called lignin, which is like the glue holding a tree together and giving it that brown color. After some tweaking, they remove or bleach the lignin and fill the wood with a see-through epoxy resin.
The result? Sheets of transparent wood that let through a whopping 80% to 90% of light. And get this – these wooden wonders are proving to be stronger than both Plexiglass and regular glass. They’re like the superheroes of screen materials, standing strong even under pressure.
So, why does this matter? Well, imagine having a smartphone with a screen made of wood – it’s not just about looking cool, but these wooden screens could be slimmer and sturdier than the glass ones we’re used to. And it’s not just for phones – they’re eyeing transparent wood for windows too, creating a sort of eco-friendly alternative to the usual frosted glass.
But hold on, there’s a catch. Right now, it’s not as green as it sounds. The epoxy resin used is made from petroleum, not the most eco-friendly source. But don’t fret – these brainy researchers are already on the case, working on substitutes like hydrogen peroxide and a bio-based polymer made from citrus peels.
Who would have thought? Wooden screens might just be the next big thing in tech!
