| Outline of Final Research Achievements |
The orientation of nematic liquid crystals is quite sensitive to the boundary condition. In this work, we study the thermal property of an orientational transition of a nematic liquid crystal observed by a fluorinated polymer surface. A high-sensitivity differential scanning calorimetry (DSC) is used for the experiments. The obtained DSC data show a step-wise change of the heat flow curve at the transtition temperature. Although a relatively large thermal hysteresis is observed, it is also found that the latent heat associated with the transition is quite small.
