Změna barvy povrchu modifikovaného dubového dřeva působením umělého slunečního záření
Rozboril, Tadeáš
This bachelor thesis conducted as an experiment is concerned by the color change of modified oak wood surface affected by artificial sun light. Part of the thesis is also focused on influence of chosen modification to the color change of oak wood surface. Samples of oak wood for experiment were modified by ammonia and by iron nanoparticles. Both modifications darken the surface of samples. Color change by the artificial sun light was measured on modified oak samples, also on subfossil and natural oak wood. The dry regime caused darkening of untreated oak, and whitening of all other samples. The wet regime caused whitening of all samples, however smallest color change was measured on samples modified by nano-iron.
