Transparent Wood

This project is funded by The European Research Council.

Transparent wood is a new emerging wood polymer composite with interesting optical functionalities. The basis of the material is careful delignification of a wood block so that the microstructure is preserved, followed by impregnation of a transparent polymer with mathing refractive index. Filling the cell wall lumen with the polymer makes the composite transparent, and also mechanically stiffer and stronger due to constrained movement of the fibres and improved stress transfer.
