| Outline of Final Research Achievements |
Two cationic polyelectrolytes, poly(3-acrylamidopropyl trimethylammonium chloride) (PAPTAC) or poly(vinylbenzyl trimethylammonium chloride) (PVBTA), have been grafted on the surface of the silica particles, and then these particles have been applied to the convective self-assembly (CSA) using hydrophilic substrates to prepare colloidal layers. When the PAPTAC-grafted silica particles (PAPTAC-Si) were used, we obtained the colloidal monolayers of a wiggle beads structure. By the CSA process using the PVBATA-grafted silica particles (PVBTA-Si), on the other hand, we succeeded in fabricating the colloidal monolayers having a somewhat constant interparticle distance, that is, a non-close-packed (NCP) structure without using any templates.
