As exemplified by ice rinks, even at temperatures below the freezing point, the ice surface undergoes melting, forming a pseudo-liquid layer known as the premelting layer. Such a premelting layer is generated not only at the ice-vapor interface but also at the ice-polymer (rubber) interface, significantly influencing the properties of the ice surface. Extensive research has been conducted on the premelting layer, which has been observed at the ice-vapor interfaces. However, the behavior of the premelting layer at the ice-polymer interface has not been clarified.
Understanding the behavior of the premelting layer at the ice-polymer interface, is considered to make a substantial contribution to the development of applications such as winter tires for automobiles. However, clarifying the behavior of the premelting layer at the ice-polymer interface due to friction is challenging, given the variability under numerous conditions such as temperature, pressure, velocity, and the surface roughness of the rubber.
In this study, we initiate all-atom molecular simulations at the ice-polymer interface using polymers such as polyethene. This allows us to analyze the molecular dynamics of the premelting layer, revealing the influence of polymers on the premelting layer and elucidating the physical properties of the premelting layer.
