| Outline of Final Research Achievements |
Colloidal crystallization dynamics of poly(N-isopropylacrylamide) microgel was investigated by using optical microscopy (OM), UV-Vis spectroscopy and so on.
Nucleation rate and crystal growth rate of the colloidal crystal were estimated from the OM observation. It was found that giant single crystal of the colloidal crystal is obtained near the melting temperature.
Crystal growth rate was analyzed based on well-known Wilson-Frenkel law. The growth rate can be well described by the equation on the assumption that colloidal particles have no enthalpic interaction with each other.
