Abstract

We produced a functional surface for restraining the solidification of water droplets by bonding antifreeze polypeptides to the surface. In this study, by various protein immobilization methods, we produced the glass surfaces bonded with antifreeze polypeptides. In order to examine the anti-icing ability, we measured ice adhesin strength to the surface. It was found that a positive correlation between ice adhesion force and the cooling surface temperature can be seen irrespective of the immobilization methods. I thought because the electrostatic interaction declined by the large dielectric constant of pure water and the shielding effect of the polypeptide.
