The interphase between a polymer film and a substrate
controls the adhesion and durability of a variety of
polymeric systems including adhesives and coatings on
plastics and metals. Interphase formation is affected by
processing conditions that control chemical kinetics,
diffusion and volumetric changes. In addition, the
interphase often includes impurities, unreacted
molecules and additives. The resulting interphase can be
a very complex structure, which is not easily analyzed.
This study, presents examples to demonstrate the
usefulness of phase shift in tapping mode atomic force
microscopy (AFM) for the characterization of polymeric
