Electro‐/Photo‐Thermal Promoted Anti‐Icing Materials: A New Strategy Combined with Passive Anti‐Icing and Active De‐Icing

Ice accretion on exposed surfaces is unavoidable as time elapses and temperature lowers sufficiently in nature, causing detrimental impacts on the normal performance of devices and facilities. To mitigate icing problems, both active de‐icing and passive anti‐icing materials (AIM) have been utilized. Traditional active anti‐icing methods suffer from energy consumption, low efficiency and high cost, while passive AIM meet the challenges of improving mechanical durability and maintaining low ice adhesion strength during icing/de‐icing cycles. Recently, new AIM are rationally designed by the combination of passive anti‐icing and active de‐icing, exhibiting efficient, reliable and energy‐saving properties. The conceptual idea is that passive AIM only need to reach a certain value of ice adhesion strength (i.e., τice
