Abstract

Environmental influences, such as ambient moisture, are well known to be detrimental to the adhesion of polymeric materials to metal surfaces. The adhesion loss does not generally correlate with the average moisture content of the polymer. Moisture accumulation at the buried polymer/metal interface is believed to be the culprit in the decrease in adhesive strength. In this work, we present measurements of the interfacial moisture content and adhesion for polymer coatings on a series of different surface chemistries. The loss of adhesive strength is found to correlate directly with the interfacial water content. As the surface treatment results in a more hydrophobic surface, the interfacial water content and fracture energy upon moisture exposure decreases.
