| Outline of Final Research Achievements |
The purpose of this research is the preparations and applications of novel liquid crystal elastomer films from cellulose such as the naturally occurring biopolymer that is friendly to environment and human body. Such liquid crystal elastomer films of cellulose derivatives are considered to exhibit Bragg reflection characteristics in the visible wavelength region as well as mechanical elasticity with deformability by force, which are suitable to next-generation photonic device applications. First, we design and synthesize the crosslinkable cellulose derivatives, and explore the rational procedures to fabricate the liquid crystal elastomer films with highly oriented molecular helical structures by self-assembly. Furthermore, novel soft photonic devices are realized by optimizing both reflection properties and mechanical elasticity of liquid crystal elastomer films of cellulose derivatives.
