• 2-4-3 Memory effect in supercooled aqueous solution of TBAB

抄録

Clathrate hydrate of tetra-n-butylammonium bromide (TBAB) is expected as a cold storage material for air conditioning, but supercooling is a problem. For visualization of the supercooling phenomenon, both the microstructure of TBAB clathrate hydrate and TBAB aqueous solution were observed by freeze fracture replica method. In the decomposition and formation processes, the generation and disappearance of the clusters were found to be explained as a significant step for the phase change. In addition, the relationship between thermal behavior, solution structure, and hysteresis phenomenon (so-called memory effect) was investigated and it was found that the memory effect can be explained by cluster generation. Further, as a cross check, structure evaluation in TBAB aqueous solution was carried out by X-ray scattering method and mutual complementary results were obtained.
