| Outline of Final Research Achievements |
Drying an aqueous suspension in which particles are dispersed, regular assembly of particles can be obtained. Repeating this process while changing the particle size from larger (e.g. 10 micron) to smaller (e.g. 200 nm), complex assembly can be obtained. Dissolving the larger particles selectively, fractal-like porous structure can be obtained which is suitable for catalyst reaction field. The problem is that it is difficult to make regular structure with high repeatability when various particle materials and sizes are taken into account. This study made clear a model for such repeated self-assembly by formularizing the interaction between various particles. In addition, mechanical strength of the structure was examined because such structure is often put in micro-fluidic systems. Finally, gas sensing function was verified showing the effect of the porous structure.
