| Outline of Final Research Achievements |
Previously, we succeeded in fabricating the non-close-packed (NCP) colloidal monolayers through self-assembly of the silica particles grafted with polyelectrolyte by free radical polymerization. In the present study, we have tried to improve the regularity of the NCP colloidal array by using the polyelectrolyte-grafted silica particles prepared by surface-initiated atom transfer radical polymerization (SI-ATRP). As a result, the polyelectrolyte-grafted silica particles were successfully obtained by SI-ATRP method, whereas the resultant colloidal monolayers failed to have a NCP structure. We have also tried to prepare the mesolens arrays by annealing the NCP colloidal monolayer composed of the polyelectrolyte-grafted silica particles and a quartz glass substrate.
