Abstract: |
In present study, the effect of two organic solvents, metanol and 1-propanol, on the deposition pattern of electrophoretically deposited TiO2 nano-particles on Cu substrate was investigated. Characterization of the obtained layer by scanning electron (SEM), atomic force microscopy (AFM) and optical microscope (OM) showed that a non-uniform porous layers were obtained in methanol, however, deposition from the TiO2/1-propanol cell resulted in the formation of a relatively uniform microstructure. The difference is attributed to considerably high deposition rate of TiO2 nano-particles in methanol as well as the formation of large aggregates within the medium over time. |
