Deuteron NMR investigation on orientational order parameter in polymer dispersed liquid crystal elastomers

Original language description

Polymer-dispersed liquid crystal (LC) elastomers have been recently introduced as a thermomechanically active composite material, consisting of magnetically oriented LC elastomer particles incorporated in a cured polymer matrix. Their thermomechanical properties are largely governed by the degree of imprinted particle alignment, which can be assessed by means of deuterium perturbed 2H-NMR. Spectra of samples with various degrees of imprinted particle alignment were recorded and the results simulated using the discrete reorientational exchange model developed for determining the dispersion of LC elastomer’s domain orientational distribution. We show that the model can be applied to measure the orientational distribution of embedded LC microparticles and successfully determine the orientational order parameter in the composite system. Thermomechanical measurements correlate well with the obtained results, thus additionally confirming the validity of the applied method.
