University of Maryland developed transparent wood that is stronger than glass
Following the successful development of transparent wood by Swedish scientists, researchers at the University of Maryland in the United States recently announced that they had separated a piece of wood from the color and chemical substances to obtain a piece of transparent wood. Tests have found that this material is stronger than glass and has better insulation properties, and its biodegradability is better than that of plastic. Researcher Hu Liangbin said: "We are very surprised how this piece of wood can become transparent."
The researchers first put the wood in boiling water for about 2 hours and added sodium hydroxide and other chemicals. This method can remove lignin from wood (molecules of lignin form the color of wood). They then poured epoxy on the block, which increased the hardness of the block four to five times.
This treated wood also has a major feature that preserves the original structure of the trees and the natural passage of nutrients. These tiny passages can transmit light like nutrients to trees. Hu Liangbin said: “Traditional wood will scatter the light coming in, but if you use this kind of wood that can produce a waveguide effect, it will allow more light to shine into the room.â€
