Abstract
A correlation was found between bulk viscoelastic relaxations and surface friction measured by friction force microscopy (FFM). The velocity dependence of friction measured on gelatin, polyvinyl alcohol (PVOH), polyvinyl acetate (PVAc), and polyethylene terephthalate (PET) films was consistent with the α and/or β relaxations as measured by traditional mechanical and dielectric methods. This discovery enables viscoelastic characterization of polymer surfaces via friction, and has the potential to probe energy dissipation on the nanometer scale. This insight has facilitated the interpretation of the images of gelatin films, which exhibit fascinating microstructure.
