The effects of temperature on structural properties, thickness and morphologies of titanium oxide... by SEM. The chemical compositions of deposited thin films were studied by EDS, and the mole ratio of O to Ti is 2.2:1. Key words: titanium oxide; thin film; chemical bath deposition; self-assembly......
by a self-assembly monolayer, their water contact angles increase (CA>140?). Also, it takes more time to transmit from high-hydrophobic to superhydrophilic for ZnO surfaces under VUV illumination after they are modified by ODS. All of the results can be helpful to realize ZnO-based wettability-gradient surfaces. Key words: ZnO; thin film; wettability; micro-nanostructure; self-assembly monolayer......
