| Outline of Final Research Achievements |
It was considered that the ice formation and attachment on the surface of the substrate can be solved by making water at the interface less likely to take the ice structure, and it will be possible to explore a new anti-icing surface. In view of this, it is fabricated a surface, that ice and water droplets do not stably deposit on the basis of composing the microstructure of the interface and the polymer properties applied to its surface and forming an antifreeze layer on the surface in nm order, Evaluation was carried out. It is investigated the structure of the water molecules present in the layer with a thickness of 100-300 nm necessary to ensure constant wet condition and water-fluid lubrication. As a result, in the polymer containing sodium ions, no significant change was observed in the ice formation and drift, whereas when the ion was changed to lithium, the desorption effect of ice was enhanced.
