| Outline of Final Research Achievements |
This study clearly demonstrated the permeation phenomena of double emulsion droplets through microporous membranes. Because it is impossible to observe in-situ the permeation behaviors in membrane pores, microchannels mimicking membrane pores were fabricated by standard soft lithography to enable the in-situ observation. Throughout the systematic experiments, three characteristic behaviors were observed: (a) passage into one channel without splitting; (b) division into two smaller components; and (c) stripping of the middle water phase of the double emulsion droplets into a smaller double emulsion droplet and a smaller water-in-oil single emulsion droplet. In addition, successful preparation of the functional microparticles with the use of the double emulsion droplets as templates were demonstrated.
