Outline of Final Research Achievements

The objective of this study is to develop an innovative technique that can actively control the characteristic of solid surface by the use of metallic nano-particles which agglomeration situation is thermally controlled. Based on the result obtained through the thermal treatment experiments and the scanning electron microscopy, the influence of thermal history on the agglomeration situation of silver nano-particles was investigated. From the relationship between the surface wetting condition of pure water on a solid surface and the agglomeration condition of nano-particles' layer on the surface, possibility of surface energy variation by the agglomeration control was indicated. Moreover, an experimental study for the improvement of adhesion strength of nano-particles' layer was performed.
