A bionic superhydrophobic surface with both micrometer and nanometer structure roughness is achieved by a simple and conventional coating–curing process on engineering materials such as stainless steel. The superhydrophobic surfaces (water contact angle of about 165°, see figure) possess very good cohesional strength and high- and low-temperature resistance, which is very important for practical industrial applications of these coatings.
