Micro/nanostructured surfaces with extreme wettability, such as superhydrophobic surfaces, are useful for various applications. Herein, we used Ar plasma to form polydimethylsiloxane films while immobilising SiO 2 nanoparticles, which were prepared on polyester fabric surfaces under mechanical stretch–release to obtain micro/nanostructures. The treated fabrics exhibited a large contact angle of 169.06° with small sliding angle of 5°. We developed corresponding micro/nanostructure models to establish the relationships between the structural parameters and the hydrostatic pressure and water-droplet bouncing. The model is useful for guiding the regulation of water pressure.
