Title: Effects of a DBD plasma discharge on bond strength
Abstract: DBD plasma treatment of polymers for adhesion properties in a printing and lamination application is explored here. The ink-substrate adhesion is dependent on the plasma dosage (watt density). At too low treatment level, lower oxidation and inferior wetting behaviour, caused a delamination failure between the water-based ink and the polymeric substrate surface. The adhesion properties, measured in a manual peel test, were clearly improved at higher plasma dosage as a consequence of the greater wetting and oxidation. There was a clear relationship between treatment level (surface chemistry and surface energy) and adhesion properties discerned, which suggests that it is the Debye interaction forces between the polar functional groups that are contributing to the bond strength between the ink and the plasma-treated substrate.
