cold plasmas have been used to modify surface properties of wood and paper to improve adhesion of glues or enhance deposition of thin layer of polymers to the surface of metals glasses and plastics [1–3]. Cold plasma is a mixture excited particles (ions, electrons, atoms, radicals, etc.) with very low degrees of ionization and little penetrating energy [4].. However,plasma particles have sufficient energy levels to break chemical bonds on the surface of organic and inorganic substrates[5,6]. The broken chemical bonds are thermodynamically unstable and combine readily with gas fragment to molecularly re-engineer the surface of the material [7].The modification(surface cleaning, ablation and degradation, cross-linking, surface oxidation and polymerization), how ever, is limited to a few molecular layers and does not affect bulk properties.
