The ice adhesion force to a metal surface has always been measured in a macro-scale, but the measured ice adhesion force is always an apparent value including a force to break the ice. To measure the correct ice adhesion force, one of the authors developed the measurement method in a nano-scale using scanning probe microscope (SPM). And it was clarified the correct ice adhesion force to the copper could be reduced by addition of non-ionic surfactant. In this study, similarly to copper, the surfactant was used, and a glass was used as a test plate. Adsorption characteristics of surfactant molecules to the glass may be quite different from that to the copper. So, ice adhesion forces and the adsorbed amounts of the surfactant were measured by the SPM and QCM, respectively, varying surfactant concentrations. And, validity of the measured ice adhesion forces was clarified based on the adsorbed amounts of the surfactant.
