By plasma treatment of wood surfaces, several properties can be changed positively for improving surface characteristics. Plasma treatment is a novel technology in the field of wood surface modification with a number of applications that have been investigated in the last decennia (Viöl et al. 2013). Some of the processes described in the literature are close to an industrial implementation. Plasma treatment at atmospheric pressure using ambient air as process gas result in increases in the polar character of the wood surface and in total surface energy. XPS measurements before and after plasma treatment revealed a significant change in chemistry of the wood surface, resulting in increased surface polarity after plasma treatment. It can be shown, that several wood surface properties can considerably be improved by a plasma treatment, such as: glueability and paintability of solid wood and wood composites, printability of WPC etc.
