Development of superhydrophilic and superhydrophobic polyester fabric by growing Zinc Oxide nanorods

► Growth of ZnO nanorods on microfibers of PET to generate hierarchical structure. ► Seed concentration affects the capillarity and diffusion coefficients of water. ► Deposition of octadecyltrimethoxysilane on hierarchical structure. ► Measurement of water contact angle and water sliding to characterize lotus effect. ► Sliding angle is directly linked to surface fraction.
