E.  aSolid softwood coated with plasma-polymer for water repellence.h[electronic resource]  c2002  cStaff cnpf.  aCold plasmas were produced by eletrical glow discharges in a gas at reduced pressure and at low frequency. The precursor gases used were ethylene, acetylene, butene-1, and vapor of vinyl acetate. The treatment caused the solid softwood surface to become hydrophobic; 1-butene-plasma produced the best results. Although the surface treatment resulted in water repellence, permeability to water vapor remained. Using a mixture of tetraethyl orthosilicate vapor (TEOS) and oxygen (O2) it was possible to investigate the inability of the glow discharge to coat the surface of wood orifices.  acontact angle  ascanning electron microscopy  awood  aMadeira  aAbsorção do vapor de água  aÂngulo de contato  aHydrophobic surface  aPlasma polymerization  aPolimerização por plasma  aSuperfície hidrofóbica  aWater vapor absoption1 aSOUZA, M.
