Reduction of Ice Adhesion Using Surface Acoustic Waves: Nanoscale Vibration and Interface Heating Effects

Ice accumulation causes great risks to aircraft, electric power lines, and wind-turbine blades. For the ice on structural surfaces, adhesion force is a crucial factor, which generally has two main sources, for exampple, electrostatic mechanical interlocking. Herein, we present that surface acoustic waves (SAWs) can be applied minimize by simultaneously reducing interlocking, generating interface heating effect. A theoretical model of considering effect SAWs first established. Experimental studies proved combination nanoscale vibration effects lead reduction substrate. With increase SAW power, decreases due dipole spacings, mainly attributed induced vibration. The leads transition locally interfacial contact phase from solid-solid solid-liquid, hence interlocking ice. This study presents strategy using device reduction, results show considerable potential application in deicing.
