PA07 AC calorimetric study on the phase transitions of aerosil-dispersed liquid crystal systems

Abstract

We had performed the AC calorimetric measurements on aerosil-dispersed liquid crystal systems and observed the frequency dependence of the phase response in N-SmA phase transition. It could be thought that this was the influence on the internal relaxation time by aerosil mixture. However, reliable analyses were difficult because the form of the present sample cell is a different form from the standard theoretical models. In this study, we have used the sample cells with a new design that is nearer to the standard theoretical model, and investigated the influence on the N-SmA phase transition by aerosil mixture.
