Outline of Final Research Achievements |
In this study, the surface thermal analyses of heat storing small molecules were conducted. The cold crystallization of small molecules can be utilized for the storage of low temperature waste heat, and the thermal behavior was analyzed. The surface topography and thermal images were captured in a high spatial resolution by scanning probe microscopy. As a result, the differences depending on the heating and cooling conditions were observed in the images. Additionally, it was suggested that the formation of a uniform crystal structure was important to the high efficient heat storing.

Academic Significance and Societal Importance of the Research Achievements |
社会における未利用熱の多くは低温排熱であり、そのエネルギーの再利用法の確立は急務である。本研究で扱った冷結晶化は、蓄熱の分野への応用が期待される。色素系の低分子において、室温付近で発現する冷結晶化挙動の解析に成功し、低温排熱の蓄熱に関する社会的意義の高い研究成果を得た。また、低分子の冷結晶化挙動を走査型プローブ顕微鏡によって微視的に解析した点は新奇であり、学術的にも意義のある成果が得られた。
