Correlating Interfacial Moisture Content and Adhesive Fracture Energy of Polymer Coatings on Different Surfaces

Abstract

The adhesion of polymer film of PMMA to different surfaces was measured using the shaft‐loaded blister test. The exposure of the films to saturated water vapor generally leads to a decrease in adhesive strength. The adhesion loss was directly related to the moisture accumulation at the polymer/substrate interface as measured using neutron reflectivity.
