Strong anti-ice ability of nanohairs over micro-ratchet structures

摘要

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 urn under-10 °C, which is attributed to the effective cooperation of the nano-and microstructures.
