Abstract

We studied the wetting properties of glycerol on mica and stainless steel (SS) using the Scanning Polarization Force Microscopy (SPFM) technique. The precise control of the polarization force between a conductive atomic force microscope tip and a substrate allowed topography profile measurements of micro- and nanodroplets of liquid, opening the opportunity for the determination of the interaction between the liquid and the substrate: contact angle and surface potential energy between the surfaces versus height of droplets. The results of these experiments offer insights into the mechanisms of wetting phenomena at liquid-solid interfaces, at the nanometer scale..
