Durable active anti-icing conductor for use in a low-temperature and high-humidity environment, and a method for preparing the same

An active anti-icing conductor for use in a low-temperature and high-humidity environment, wherein a surface ice adhesion strength of the active anti-icing conductor is not greater than 5 kPa;

• wherein the active anti-icing conductor is a dendritic composite porous structure formed on an aluminum substrate;
• the dendritic composite porous structure is configured to comprise an upper layer and a lower layer, wherein a total pore depth of the dendritic composite porous structure is 5-31 μm;
• a pore diameter of an upper pore in the upper layer is smaller than a pore diameter of a lower pore in the lower layer, and a pore diameter ratio of the upper pore to the lower pore is 1:3~1:2;
• a pore depth ratio of the upper pore to the lower pore is less than 1:2;
• a ratio of number of the upper pore to number of the lower pore is 4-6:1;
• both the upper pore and the lower pore are filled with a modifier and a lubricant;
• a surface porosity of the dendritic composite porous structure is 50-66% with an inter-pore spacing of 10-38 nm.
