Fabrication method for hydrophilic aluminum surface and hydrophilic aluminum surface body

Abstract

A method for fabricating a hydrophilic aluminum surface includes: an activation step of preparing doped aluminum having an activated surface through doping treatment on a part or whole of an aluminum surface with applying reactive gas thereto; and a structure forming step of preparing a hydrophilic aluminum surface through oxidizing treatment on the doped aluminum to have nano-patterns comprising nano-protrusion structures on the aluminum surface. Hydrophobic aluminum can be fabricated into artificially hydrophilic or super-hydrophilic aluminum, and the hydrophilic aluminum surface body that does not have an aging effect and has long-lasting hydrophilicity can be provided.
