The viscoelasticity of the rubber-ice interface determined by resonance shear measurement: influence of rubber <i>T</i> _g.

ABSTRACT: We performed resonance shear measurements (RSM) using the low-temperature surface force apparatus (LT-SFA) to investigate how rubber composition influences the viscoelasticity of the rubber-ice interface. RSM data showed quite different behaviours depending on the styrene contents (5, 23 and 45 wt%) of poly(styrene-co-butadiene) rubbers. A mechanical model for RSM was applied to obtain the interface's viscous (b _s) and elastic (k _s) parameters across a temperature range of ca. -20°C to 0°C. All rubber-ice interfaces at a temperature of ca. -18° to -10°C showed a significant decrease in viscosity of 1 to 2 orders of magnitude in the maximum compared to the silica-ice interface, presenting properties of the ice premelted layer. This was attri
