Abstract: Unexpected ice accumulation tends to cause many problems or even disasters in our daily life. Based on the superior electrothermal and photothermal function of the carbon nanotubes, we introduced a superhydrophobic/electrothermal/photothermal synergistically anti-icing strategy. When a voltage of 15 V was applied to the superhydrophobic sample, the surface 
could rapidly melt the ice layer (~ 3 mm thickness) within 530 s at the environmental temperature of ? 25 °C. When the 
near-infrared light (808 nm) irradiates on the superhydrophobic sample, the ice could be rapidly removed after 460 s. It was 
found that the superhydrophobicity helps the melted water to roll off immediately, and then solves the re-freeze problem the 
traditional surfaces facing. Moreover, the ice can be completely melted with 120 s when the superhydrophobic/electrothermal/
photothermal synergistically anti-icing strategy was utilized. To improve the mechanical robustness for practical application, 
both nanoscale carbon nanotubes and microscale carbon powders were utilized to construct hierarchical structure. Then 
these dual-scale fi llers were sprinkled onto the semi-cured elastomer substrate to prepare partially embedded structure. Both 
hierarchical structure and partially embedded structure were obtained after completely curing the substrate, which imparts 
excellent abrasion resistance (12.50 kPa, 16.00 m) to the prepared sample. Moreover, self-healable poly(urea–urethane) 
elastomer was introduced as the substrate. Thus, the cutted superhydrophobic sample can be mended by simply contacting 
at room temperature.
