Abstract
ABSTRACTThe present paper describes an unconventional approach to fabricate superhydrophilic-superhydrophobic template on the TiO2nanotube structured film by a combination of electrochemical anodization and photocatalytic lithography. Based on template with extreme wetting contrast, various functional nanostructures micropattern with high resolution have been successfully fabricated. The resultant micropattern has been characterized with scanning electron microscopy, optical microscopy, X-ray photoelectron spectroscopy. It is shown that functional nanostructures can be selectively grown at superhydrophilic areas which are confined by the hydrophobic regions, indicating that the combined process of electrochemically self-assembly and photocatalytic lithography is a very promising approach for constructing well-defined templates for various functional materials growth.
