冰对固体表面的粘附已经被许多研究者包括作者之一研究过。同时,作者小组阐明,可以通过改变表面活性剂浓度来主动控制由于表面活性剂分子吸附到固体表面的过冷度。在这项研究中,通过吸附到铜表面的冰粘附力的控制和其主动控制通过不同的表面活性剂浓度进行了研究。将表面活性剂-纯水混合物在固定表面温度下冷冻在铜表面上,并通过SPM测量不同表面活性剂浓度的粘附力。同时,吸附到铜表面的表面活性剂的量也通过QCM测量,改变表面活性剂浓度。基于冰粘附力与表面活性剂吸附量之间的关系,评价了粘附力主动控制的可能性。
Adhesion of ice to a solid surface has been investigated by many researchers including one of authors. While, authors group clarified that it was possible to actively control a supercooling degree due to adsorption of surfactant molecules to a solid surface by varying surfactant concentrations. In this study, control of the ice adhesion force through the adsorption to a copper surface and its active control by varying surfactant concentrations are investigated. A surfactant-pure water mixture is frozen on a copper surface at a fixed surface temperature, and the adhesion forces are measured by a SPM, varying surfactant concentrations. While, the amounts of surfactant adsorbed to a copper surface are also measured by a QCM, varying surfactant concentrations. The possibility of active control of the adhesion force is evaluated based on the relationship between the ice adhesion force and the amount of adsorbed surfactant.
