Abstract

In the present work we investigate the wetting behaviour of nanotubular TiO₂ layers (π-TiO₂) grown by electrochemical anodization of Ti. As-prepared π-TiO₂ layers show a super-hydrophilic behaviour while π-TiO₂ layers covered by octadecylphosphonic acid (C₁₈H₃₇PO(OH)₂) monolayer show super-hydrophobic behaviour. We demonstrated that the wetting properties significantly depend on the nanotube diameter.
