Effect of DCSBD plasma treatment distance on surface characteristics of wood and thermally modified wood
Original language description
This study focused on plasma treatment of European beech (Fagus sylvatica) and heat-treated European beech surfaces with varying distance from the planar electrode of the diffuse coplanar surface barrier discharge. In addition to the treatment in the air, plasma treatment was also carried out in O2, CO2, N2 and Ar atmospheres. Treatment was differentiated between treatment in the active plasma zone and in the so-called plasma afterglow region. Air plasma treatment in the active plasma zone led to the well-known improvement of surface wettability of polar liquids due to increased polar part of surface free energy. Treatment in plasma afterglow region caused the wettability decline of polar liquids and caused a more hydrophobic surface. The phenomenon was primarily present for air plasma treatment. Oxygento-carbon ratio measured by X-ray photoelectron spectroscopy did not change with the treatment in air plasma afterglow. Based on additional tests with pure cellulose paper and based on findings in previous studies, the reason for increased hydrophobicity was suggested to be degradation of hemicelluloses on the wood surface.
