| Outline of Final Research Achievements |
In this study, I aimed a creation of multi stimuli-responsive materials based on gel with ordered structure consisting of imogolite nanotube (later denoted imogolite gel). Firstly, change in viscosity and birefringence of imogolite gel were confirmed by application of heat and electric field that encourages an utilization of imogolite gel as multi stimuli-responsive material. Secondly, I prepared imogolite gel with oriented structure in narrow spacer. Finally, I found that gelation and oriented structuring of the imogolite nanotubes induced rapid changes in the birefringence of their gels.
