Abstract
Time-resolved FTIR-spectroscopy is employed to study structure and mobility in ferroelectric LC polymers and elastomers (temperature range 20°C…130°C, dynamic range 0.1 Hz… 105 Hz). Due to its specifity the analysis of the (polarized) IR-spectra enables to determine the average orientation, the orientational order and the mobility in response to an electric field for the different molecular moieties (phenyl group, the polar groups, the methylene spacer and the polymer backbone). Furthermore the phase relationship in the motion of the different molecular groups can be extracted.
