SURFACE PROPERTIES OF HYDRO-THERMALLY MODIFIED BEECH WOOD AFTER RADIO-FREQUENCY DISCHARGE PLASMA TREATMENT
Heat treatment is widely used to improve the properties of wood, in particular its color. However, this treatment causes changes in the surface properties of wood, the surface becomes hydrophobic, which can cause serious problems when gluing or coating. In this study, the radio-frequency discharge (RFD) plasma was used to increase the hydrophilicity of the steam-modified beech (Fagus sylvatica L.) wood due to the formation of various polar groups (e.g., hydroxyl, carbonyl, carboxyl, etc.). The increased surface polarity improves the wettability and hydrophilicity due to oxidation reactions. Tensile shear strength properties of lap joints were processed according to EN 205. Plasma-treated samples showed higher strength when compared to plasma-non treated samples after the D4 test according to EN 204.
