Abstract:
Two aerogel systems containing a ferroelectric liquid crystal (FLC) with smectic phases over a wider
temperature range are investigated using dielectric spectroscopy. The second order transition from Sm-
A to Sm-Cp is considerably broadened and the collective modes are detected for the FLC confined in
aerogel pores. An additional relaxation process (AP) seen in these confined systems arises from the
interface layer, the relaxation strength of AP decreasing and of the Goldstone mode gradually increasing
as temperature is lowered.
