WOOD SURFACE MODIFICATION BY DIELECTRIC BARRIER DISCHARGES AT ATMOSPHERIC PRESSURE

The effect of plasma treatment at atmospheric pressure on surface properties of wooden samples is investigated in this work. Plasma activation of wooden surface was studied in diffuse coplanar surface barrier discharge created in air to obtain wettable surface. Plasma deposition of hydrophobic coatings directly on the surface of wooden materials using surface barrier discharge created in pure nitrogen with small admixture of hexamethyldisiloxane was investigated too. Surface properties of plasma treated wooden samples were studied using the sessile droplet technique to identify surface free energy of treated and untreated samples.
