Abstract:
A strong anti-ice property of nanohairs over micro-ratchet surfaces is observed. A long freezing delay of more than 185 min is achieved for a droplet on the nanohairs over ratchet structure with a period of ∼290 μm under -10 °C, which is attributed to the effective cooperation of the nano- and microstructures.
