There has been considerable research on reducing the force of ice adhesion to cooling solid
surfaces. One of the present authors has also studied various methods of reducing or
increasing the ice adhesion force. One promising method involves the use of a thin silanecoupler
film coated on the solid surface. Using this method, the ice adhesion force can be
controlled by altering the organic functional groups of the silane-couplers. However, the
characteristics of such thin films usually depend on their formation conditions. Therefore,
in this work, two kinds of silane-couplers were investigated. The thin film coating thickness
and ice adhesion force to the coated test plate were measured for two kinds of test
plate materials, test plate immersion times in the silane-coupler mixtures, and silanecoupler
concentrations. Moreover, a durability of surface modification effect due to the
thin film and a mechanical durability of the thin films were also investigated.
