The Device Using a Polydimethylsiloxane Membrane and the Phase Transition of Water

The accumulation of ice on surfaces can cause harm in many industries. Our work describes an experiment and a simulation the deicing effect based simple device combining polydimethylsiloxane (PDMS) membrane water phase transition. resulted minimum adhesion strength 0.327 kPa, was still less than 5 kPa after 15 cycles, which meets requirements automatic deicing. It also held up flushing with sand currents. In addition, our finite element illustrates that decreases greatly due to change initial stress distribution separation mode ice. fracture between initiates from one side, propagates gradually along contour while at same time spreading rapidly towards center. Compared other icephobic methods, such as expensive vulnerable micro/nano-surfaces or functional composite coatings, this low-cost environment friendly appears promising for large-scale applications various engineering fields.
