Abstract
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 SiO2 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.
