Abstract
A low-cost and all-weather hybrid anti/de-icing method combining electrothermal and photothermal superhydrophobic coating was proposed. The photothermal superhydrophobic coating was prepared by using cuttlefish ink as a light-absorbing material, and the contact and rolling angles of the coating surface were 154.1° and 3.1°, respectively. Under the same light intensity, the accumulated ice on the hybrid anti/de-icing sample surface melted within 414.1 s, while the accreted ice on the aluminum alloy surface didn't melt within 700 s. In the test of melting the accumulated ice by electric heating, the melting time of the accumulated ice on the hybrid anti/de-icing specimen surface was 214.4 s shorter than that of the accreted ice on the aluminum alloy surface, and the energy consumption was also reduced by 41.73 %. The hybrid anti/de-icing specimen has good droplet bouncing properties. Meanwhile, the photothermal superhydrophobic coating maintained a contact angle of 140° after being impacted by 5 kg of quartz sand. Additionally, a large area of anti/de-icing sample was prepared, and the accreted ice on the sample was automatically peeled off by artificial vibration. However, the accumulated ice on the aluminum alloy and flexible film substrate surfaces of the same dimensions as the anti/de-icing specimens was not peeled off. This study presents a practical, easily prepared, and scalable anti/de-icing method with excellent performance, offering a potential solution to the engineering field.
