The ice adhesion force cannot be correctly measured using conventional macroscale methods because of the unevenness of the solid surface, especially, the metal surface. Thus, under a sufficient relative evenness of the copper surface to ice realized by forming nanoscale ice particles using a scanning probe microscope, the ice adhesion forces to the copper at various surface temperatures have been previously measured by one of the authors. Furthermore, reduction of the ice adhesion force to the copper surface at -5°C due to the addition of surfactant has also been previously realized. In the present study, ice adhesion forces to four types of metal with added surfactant were measured and compared with the results without surfactant. And validity of measured ice adhesion forces for four metals was clarified based on the adsorbed amounts of the surfactant molecules to four metals, the surface energies of ices with and without surfactant, and those of the metals.
