Abstract The anti-icing behavior of static and dynamic low-temperature droplets on the surface of microelectronic material was investigated. The ZnO-coated superhydrophobic surface (SPS), hydrophobic surface (HPS), hydrophilic surface (HS) and pure Cu surface were prepared by hydrothermal method and ultraviolet light irradiation. Under the static and dynamic anti-icing condition, the SPS had excellent anti-icing ability before −20 °C. Even if the temperature was −20 °C, the SPS still have longest delayed icing time when compared with other three surfaces. This work offers a theoretical guidance for anti-icing application of microelectronic materials.
