理由
A thermal conductivity measurement setup (frequency domain thermal reflectance) has been constructed. And we also extend the FDTR setup into an imaging technique capable of producing micrometer-scale maps of several thermophysical properties simultaneously by introducing a mapping stage. And I also have learned some other thermal conductivity measurement methods, such as the 3 omega method, TDTR, laser flash, and the steady-state method. With these methods, severy interesting samples have been investigated, such as FeRh and platinum thin film. In the future, these methods can also be used to investigate amorphous hydrogels and ordered hydrogels.

| 今後の研究の推進方策 |
1. Fabrication of ordered hydrogels. In this step, the ways of fabricating ordered hydrogels will be investigated. Recent works have reported novel highly ordered hydrogels by electric field, magnetic field, mechanical force, self-assembly, and freezing casting. Those works mainly focus on mechanical behavior, but the ways they used to align hydrogels can be learned in order to find suitable fabrication methods for our research.
2. Experimental measurement of the thermal conductivity. In this step, the thermal conductivity of the ordered hydrogels will be measured experimentally by the 3ω method, the hot-wire method or other suitable methods.
