Increased PVA-Glue Adhesion on Particle Board and Fibre Board by Plasma Treatment

Effects of Nanosilver-Impregnation and Heat Treatment on Coating Pulloff Adhesion Strength on Solid Wood

“…Wood is frequently modifi ed by engineering processes to get stiffness or homogeneous mechanical properties because only few species exhibit radial and axial uniformity. Moreover, some surface preparation techniques were used for better adhesion of wood surface (Militz and Viöl, 2008;Militz et al, 2013).…”

Nanocomposite coatings and plasma treatments for wood-based products

“…In most cases, the goal was to improve the adhesion of a polymeric based coating in a composite product (Carlsson and Ström, 1991;Felix et al, 1994;Sakata et al, 1991). Various studies have since investigated the surface wettability of wood from several species treated through reduced-pressure plasmas (Aydin and Demirkir, 2010;Abbasipour et al, 2012;Acda et al, 2012) and, more recently, atmospheric DBD plasmas (Wolkenhauer et al, 2008Odrášková et al, 2008;Avramidis et al, 2009Avramidis et al, , 2011Avramidis et al, , 2012Sakata et al, 1993;Topala and Dumitrascu, 2007;Lukowsky and Hora, 2002;Wielen et al, 2005). Their work showed that Douglas and Colorado fir exhibited increased permeability when exposed to N 2 , but this modification did not prove permanent due to the migration of extractives to the treated surface over time.…”

Plasma treatment of wood and wood-based materials to generate hydrophilic or hydrophobic surface characteristics

“…Thus, plasma treatment can be used either to increase hydrophilicity and wettability for enhanced adhesion or to increase hydrophobicity as a protective measure. Several publications deal with plasma surface modification of wood and wooden materials to increase hydrophilicity, and improvements in surface free energy, wetting behaviour, adhesion properties and hardening of coating systems have been reported (Lukowsky & Hora, 2002;Evans et al, 2007;Tóth et al, 2007;Wolkenhauer et al, 2008cWolkenhauer et al, , 2009b. In the present study a dielectric barrier discharge (DBD) using ambient air at atmospheric pressure was applied for surface modification of wood and wood-based materials.…”
