The measurements of interfacial moisture content and adhesion for a series of polymer coatings having different surface chemistries, were investigated. Measurements were made after reaching an apparent equilibrium in either a dry (0% relative humidity) or wet (100% relative humidity) environment. The loss of adhesion is found to correlate directly with interfacial water content. The results show that the surface treatments that resulted in a more hydrophilic surface, lead to an increase in the interfacial water content and a decrease in the interfacial fracture energy.
