Colour stability of oak wood treated with iron oxide nanoparticles and ammonia fuming

Popis výsledku v původním jazyce

The paper deals with reactive wood staining by ammonia and iron oxide nanoparticles. These techniques are used for changing the colour of wood surface. Darkening of wood surface is an increasing demand from customers. This study investigates and evaluates the efficacy of colour wood modifications and the influence of accelerated ageing on wood surface. Both chemical modifications led to darkening of oak surface and nanoiron treatment gave the oak surface a darker colour. All modified samples get gradually lighter during exposure compared to unmodified oak, which intensively darkened at the beginning of exposure. All samples similarly showed reddening and yellowing of wood surface. The most intensive change in chromaticity para-meters was observed in nanoiron treated oak and is explained by the oxidation of iron and rust occurrence.
