Ice adhesion to a cooling solid surface often occurs in the formation process of ice slurry and causes decrease in ice formation rate, while recently, strong adhesion force of ice is positively used to fix a workpiece. Thus, it is necessary to control ice adhesion force. However, the control is indeed a nasty problem to handle. In this paper, a simple coating method of thin film made from a silane-coupler to control ice adhesion force to the cooling solid surface was proposed, and effect of the thin film was investigated. And an optimal condition for combination of immersion time and mixture temperature was clarified. And under the optimal condition, it was also clarified that control of ice adhesion force by using the film was possible and durability of effect caused by the thin film was much long.
