| Outline of Final Research Achievements |
We accomplished the fabrication of optically and electrically functional materials based on industrially available cellulose derivatives (cellulose acetate (CA) and cyanoethyl cellulose (CyEC)), by controlling the orientation state of polymer chains and segments via combination of mild chemical modification and thermal processing. With regard to optical functionality, we synthesized CA-based graft copolymers by atom transfer radical polymerization; their optical anisotropy was delicately controllable by changing the copolymer composition, which is of great significance for designing optical retardant films including a specialty that shows a zero-birefringence nature irrespective of the elongation and ensuring molecular orientation growth. As electrically functional materials, we successfully obtained thermally-stable highly dielectric derivatives of CyEC.
