AFM Rupture Length Analyses of Material Surfaces

Abstract

This study provides analyses of the Atomic Force Microscope (AFM) rupture length, which is the longest distance in the Z-direction where the adhesion is obtained by release force curves. Clear XY rupture length images were obtained from the results. In this paper, we showed that there is a difference in the distribution of adhesion force vs rupture length plot on the surface of silica particles with different surface treatment materials, and that clear rupture length images of LiB binder and polymer film with a sea-island structure could be obtained. From these, we concluded that the AFM rupture length can be a valid parameter for material surface as well as the adhesion force.
