| Research Abstract |
It was found that when solids of 1H, 1H, 2H, 2H-henicosafluoro-1-dodecanol(FC12OH) and 1-hexadecanol(C16OH)were placed on the water simultaneously, a monolayer is spontaneously formed. From the thermodynamic and dynamic study, it was found that the composition of the monolayer changes from C16OH-rich to FC12OH-only. It was also clarified that the monolayer took four different states and thus two triple points existed in the phase diagram.
