Outline of Final Research Achievements

We have investigate the dynamic coupling between hierarchical structure and dynamics of internal degree of freedoms in soft matter. On the basis of design for the dynamic nature of the nano-interfaces embedded on the hierarchical internal structure, We try to establish the fundamental concept of the sophisticated functions of soft matter. We have introduced slippery interfaces on the homeotropic SmC* liquid crystals in IPS cell by the phase separated liquid droplets. We have found the drastic reduction of the driving voltage keeping the response time is fully fast in comparison with the original material. We have succeeded in controlling the hold and release of dye molecules using liquid crystalline nano-emulsions. We have proposed the novel alignment methods for the nematic liquid crystal cells by using coated by low glass transition polymers without the rubbing.
