"Wooden Wonder: The Future of Smartphone Screens May Be Forest-Sourced"
Researchers are developing transparent wood as a stronger and potentially more sustainable alternative to glass and plastic for smartphone screens and other applications. This innovative material allows for high light transmittance and is significantly stronger than traditional screen materials. The process involves removing the lignin from wood and replacing it with epoxy resin, although efforts are ongoing to find more environmentally friendly substitutes for the resin. Transparent wood could also be used for smart windows that transition from clear to tinted.
