The cold plasma was used to improve the hydrophilicity of oak wood. A significant increase of the polar component of oak wood surface energy after modification by cold discharge plasma has been observed. The polar component of the surface energy is associated with the presence of acid-base forces (electron donor-acceptor bonds). FTIR spectra confirm the changes in C=O and C–O–C bonds that occur on the cold plasma modified wood. The integrated intensities ratios of oxygen function absorption with the majority of polar –OH groups contribution with a maximum at 3400 cm-1 and a maximum of non-polar CH2-groups with a maximum at 2985 cm-1 (–CH2 groups)sym shows an increase of the ratio P(OH)/P(– CH2) during plasma treatment of the oak wood.
