Molecular orientation of Liquid Crystal polymer thin films

Liquid crystalline polymer thin films can be studied using C K edge resonant soft x-ray reflectivity. Here is shown in particular the study of side-chain orientation of Poly-phenoxyethyl acrylate thin films. The refraction index ellipsoid has been obtained by a quantitative analysis using the Berreman formalism.

A depth profiling study of molecular orientation in liquid crystalline polymer thin films with nanometer resolution is presented. C K edge resonant soft x-ray reflectivity has been used to probe the side-chain orientation of Poly-phenoxyethyl acrylate thin films. The refraction index ellipsoid has been obtained by a quantitative analysis using the Berreman formalism.
