Abstract

A transparent and super-hydrophilic TiO2 film with high adhesion was prepared by simple self-assembly methods from aqueous solution at low temperature. The excellent adherence of TiO2 films was accomplished by introducing a buffer layer with sulfonate-modified surfaces and nanoasperity. Moreover, the structure and morphology of the films were successfully controlled by deposition temperature and the pH of precursor solution. By optimizing the several parameters of solution as well as the surface functionality of the substrate, the nano-structured TiO2 film with high adhesion showed a water contact angle of below 5° and the relative transmittance to slide glass of over 90%. The fabricated TiO2 film deposited under the optimized condition is not removed from substrate after several Scotch tape (STT) tests and immersing into several kinds of solvent.
