Researchers in Sweden have created a completely transparent wood material made entirely from biological materials, including agricultural by-products like citrus peels, an innovative invention in building materials.
Lignin is the main light-absorbing component of wood. The key process to create transparent wood is to remove the lignin, fill the holes with other materials, and restore the hardness of the wood to create a wood material that has the support of wood and is fully transparent.
Researchers at the KTH Royal Institute of Technology in Sweden first invented transparent wood in 2016, which uses plastic to fill the holes left by the lignin. Plastic is a petroleum-based product.
The study, published May 2 in the journal Advanced Science, used citrus peel extract limonene acrylate instead of plastic to create a new product that not only has zero pollution, but also effectively uses citrus, a waste material from juice manufacturers. peel.
The study says the material is strong and durable and can be used as a building material for structural support. There are a wider range of uses beyond that, including smart windows, heat-storing wood, wood with its own lighting, and more.
We looked at the way light passes through the material and what happens when the light touches the cellulose,” said Lars Berglund, a professor in the Department of Fiber and Polymer Technology at the Royal Institute of Technology in Sweden. Some of the light passes directly through the wood, making the material transparent. Some light is refracted and scattered at certain angles, which can produce beautiful effects for use as illumination.”
