【Abstract】 A novel process to gain clear and high edge acuity micropatterns of TiO₂ thin films by direct microcontact printing was presented in this paper. Using TiO₂ sol as the “ink”, poly（dimethylsiloxane） elastomeric stamp was taken to transfer the TiO₂ colloids to the substrate. The process is different from the traditional process using the SAMS to induce the deposition of TiO₂. The new way increases the transferred efficiency of the micropatterned TiO₂ thin films. The optical micrographs and SEM show that the micropatterned structures of TiO₂ were microscale and uniform over a large area as well.更多还原
