Outline of Final Research Achievements

This research was directed toward the design and composition of functional anisotropic materials based on cellulosic polysaccharides by controlling their characteristics of molecular assembly in combination with other polymeric/inorganic ingredients. The successful examples included miscible blends of cellulose ester/synthetic polymer applicable to optical films, cellulose nanocrystal sheets oriented variously by mechanical or magnetic force, polysaccharide-iron oxide nanohybrids showing anisotropic response to the external magnetic stimuli, calcium carbonate-mineralized polymer composites with cellulosics providing a chiral nematic mesomorphic structure, thermotropic liquid crystals of novel cellulose derivatives having an imidazolium group in the side chains, and so forth.
