The researchers have now successfully tested an environmentally safe alternative: limonene acrylate, a limonene-derived monomer. They published their findings in the journal Advanced Science. "The current limonene acrylate is made from organic citruses, such as peel waste from the orange juice industry," says Céline Montanari, lead author and Ph.D. student. The polymer that restores the strength of delignified wood while allowing light to pass through...

Stripping out polymers that block light from passing through wood and replacing them with a derivative from citrus peels Swedish scientists created a transparent composite that could replace glass.

Researchers use orange peel extract to create renewable transparent WOOD that could soon be used in smart windows To make see-through wood, scientists strip out the lignin, a polymer in the cell walls that blocks most light  Earlier attempts at transparent wood replaced lignin with fossil-fuel polymers A new eco-friendly composite utilizes a monomer made from citrus peel extract   It's capable of heavy-duty performance and is intended for structural use It could eventually be used in smart windows and even wooden lasers

Credit: Céline Montanari Since it was first introduced in 2016, transparent wood has been developed by researchers at KTH Royal Institute of Technology as an innovative structural material for building construction. It lets natural light through and can even store thermal energy. The key to making wood into a transparent composite material is to strip out its lignin, the major light-absorbing component in wood. But the empty pores left behind by the absence of lignin need to be filled with something that restores the wood's strength and allows light to permeate. In earlier versions of the co...
