The water contact angle of various wood species treated by radio-frequency discharge (RFD) plasma in air decreased with activation time from 75 up to 40 deg. The growth of water contact angle of plasma-treated wood from 37 up to 68 deg during aging was faster within 2 days after the plasma pre-treatment. The water contact angles of tested wood species showed a steep decrease after activation by RFD plasma in air. Water contact angles were markedly increased during the first 2 days of aging. RFD plasma-treated wood surfaces should be treated up to 2 days after modification by plasma. The unmodified beech wood sample shows lower roughness compared to wood surface treated by RF-plasma. Higher roughness of the plasma-treated wood samples is related to the ablation of amorphous lignin on the surface of the beech wood.
