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.
