Abstract

A typical nanostructured titania super hydrophilic film was chosen for general characterization employing a Scanning Probe Microscope(SPM)and an electrochemical measurement system.Following from the principles of the solid state chemistry and nanomechanics,intensive theoretical. analyses on the SPM images,the oxygen vacancy concentrations and the mechanism of the super hydrophilicity were made;further illuminations on a reaction equation of titania defect formation,a tentative universal surface physical mode for the wet ability,a concept,amphiphobicity,and surface design were carried out after the author's previous introduction and proposal in the end of 1999.
