Figure 1

(a) Schematic representation of the preparation procedure based on electrodeposition of a rough TO film on steel. Insets represent intrinsically hydrophilic steel substrates (water CA ∼70°) that become superhydrophilic (water CA 0°) after electrochemical deposition of a rough TO film, and transform to superhydrophobic wetting state (water CA >170°) after chemical functionalization. (b–d) TO films were deposited on several working electrode geometries made from various grades of steel: (b) an AISI 304 grade stainless-steel sheet and a pipe with 0.5 cm inner diameter, (c) a surgical-grade steel scalpel blade and syringe needle coated with TO on both internal and external surfaces, and (d) a naval construction HY-100 grade steel plate. Scale bar, 1 cm.
