| description | Superhydrophobic coating with photothermal and electrothermal conversion characteristics is considered as an ideal candidate in anti-icing and deicing fields. Nevertheless, when electrical heating is employed for deicing, the multifunctional material mentioned above is exposed to electric current, posing a certain degree of danger to operating equipment and operators. To address this problem, in this work, a photothermal/electrothermal superhydrophobic material with electrical insulation property was developed using a layer-spraying method, which consisted of a substrate with thermal insulation capability, an electrothermal layer, an electrically insulating layer and a photothermal superhydrophobic layer. The experimental results showed that the prepared sample had remarkable anti-icing ability due to its superhydrophobicity, where the freezing time of water droplet on it was extended to 611 s. Moreover, the frozen droplet on the sample can melt and be removed freely in 255 s under a light intensity of 1 kW m ^−2 or in 52 s at a load voltage of 36 V, implying that the sample possessed excellent photothermal and electrothermal deicing performance. Meanwhile, 10008 kΩ of resistance of the electrically insulating layer also ensured the safety of electrothermal deicing operation. Additionally, the sample had outstanding mechanical stability and self-cleaning ability. As a result, the developed photothermal/electrothermal superhydrophobic material with electrical insulation property can not only achieve all-day, low-energy and efficient anti-icing/deicing but also prevent the risk of current leakage during electrical heating for deicing, which shows broad application prospect in anti-icing and deicing fields. |
