Understanding the relationships between network
structure and surface and interface properties of epoxy
resins is a subject of great interest in many
applications including adhesives, coatings and
fiber-reinforced composites. However, this subject has
not been fully invevestigated partly because of the
spatial resolution limitation of traditional surface
analytical techniques. Atomic force microscopy (AFM) is
increasingly used for studying sub-micrometer features
of polymer surfaces and interfaces. In this study, the
influence of epoxy equivalent mass and epoxy/amine
stoichiometry on surface and interface microstructures
and wetting properties of amine-cured epoxy is
investigated using AFM and contact angle measurements.
