FT-IR Spectroscopy on Ferroelectric Liquid Crystal Polymers and Elastomers — •Michael Tammer1, Rudolf Zentel2, and Friedrich Kremer1 — 1University of Leipzig, Faculty for Physics and Earth Siences, Linnestr. 5, 04103 Leipzig — 2University of Mainz, Institute of Organic Chemistry, Duesbergweg 10-14, 55099 Mainz
Time-resolved polarized Fourier Transform Infrared (FTIR) Spectroscopy is employed to analyse the structure and dynamics in ferroelectric liquid crystal (FLC) polymers and elastomers. The specifity of the IR-spectroscopy enables us to study for the different molecular moieties the response to external mechanical end electrical excitations. By that, subtle details of the microscopic motion such as angular excursion, reorientation time, order parameter, asymmetries in the reorientational behaviour or elastomeric memory effects can be unravelled for the system under study.
