Outline of Final Research Achievements

Hybridization of layered silicate fine crystals (mainly smectite like layered silicates) has been investigated to explore synergic functions. Direct crystallization of the smectite-like layered silicates was employed onto various silica substrates (spheres, fibers, hollow microcapsules, and so on). Successful deposition of the crystals with homogeneous and thinner layers was verified to maintain the morphology of the original silica substrates. These hybridized materials have been applied to (1) filtration with adsorption of cationic organic contaminants, (2) building units of colloidal crystals, (3) controlled release materials for a cosmetic using, (4) HPLC column packing materials for chiral discrimination with a saving amount of eluent, and (5) magnetically collectable adsorbent/catalyst supports.
