| Outline of Final Research Achievements |
Nucleation behavior in segmented flow such as droplets and slug flow was investigated from the viewpoints of crystallization and soap-free emulsion polymerization. Nucleation analysis using microfluidic crystallization realized the measurement of nucleation rate. In soap-free emulsion polymerization using microchannels, we found the new polymerization behavior containing fast mass transfer and controlled nucleation. These findings are promising to improve the efficient production tool and the materials design.
