| Outline of Final Research Achievements |
In this study, effect of surface nano-roughness on dynamic wettability was studied. At first, uniformed 2D colloidal particle (polystyrene beads) films were fabricated on a glass substrate in the similar manner to LB method. Then, SiO2 thin films with 2D inverse opal structure were fabricated by sol-gel method. Their wettability seemed to depend on the film structure, especially in terms of dynamic wetting process. Furthermore, pinning of a water droplet at three-phase-line was also observed.
