Abstract: The present invention provides a process for the preparation of a super water repellent surface comprising the steps of arranging a plurality of spherical beads on the surface of a substrate to form a (N)-th bead layer, etching the substrate surface with the (N)-th bead layer as etching mask, arranging a plurality of spherical beads, which are larger than the (N)-th beads in diameter, on the substrate surface to form a (N+1)-th bead layer, etching the substrate surface with the (N+1)-th bead layer as etching mask, removing the beads from the etched substrate surface and coating a fluorine compound on the substrate surface on which a hierarchical concavo-convex structure has been formed, wherein the (N+1)-th bead layer forming step and the (N+1)-th etching step are repeated for N times.
