Abstract
This strategic project focuses on novel modification and functionalization methods for wood and other lignocellulosic materials leading to reduced emissions, hard wearing surfaces and tailored properties for indoor and outdoor applications. Regarding solid wood, the natural feel and optic of solid wood should be retained. Furthermore, undesired emissions or leaching effects have to be avoided. The creation of extremely water repellent super-hydrophobic wood surfaces (characterized by water contact angles higher than 150° and sliding angles lower than 10°) is one novel, promising strategy. Environmental friendly or bio-based substances shall be applied in order to meet customer demands as well as legal or voluntary regulations (e.g. eco-labels). Sharply reduced water uptake could improve the performance of wood both in outdoor weathering and critical indoor applications and the service life could be prolonged.
In conclusion it is claimed that: novel methods of functionalization lead to enhanced material properties regarding hydrophobicity, colouring, UV-stability, durability, emissions and mechanical performance of wood.
