Abstract:

The buildup of water many monolayers thick at the coating/substrate interface is the major cause of adhesion loss when an organic-coated substrate is exposed to water or high relative humidities. Until now, it has not been possible to correlate the buildup of the interfacial water layer with adhesion loss because there has been no method available to quantify the water layer at the coating/substrate interface or the adhesion loss of coated substrates. In this study, the thickness of the interfacial water layer and the adhesion loss of several organic film/substrate systems exposed to water were measured and analyzed to establish the correlation between water at the interface and the adhesion loss of organic-coated materials.
