Flexible superhydrophobic films with the electrothermal and photothermal response for enhanced passive anti-icing and active de-icing

•Exhibits excellent superhydrophobicity and electrothermal/photothermal properties.•Investigated the three-line synergistic icephobicity of multi-responsive films.•Films have outstanding mechanical, chemical and thermal stability.•Films with great processability are expected to be used in various fields.
