Electro-optical response in PDLC films

Electrooptical characteristics of the polymer dispersed liquid crystal (PDLC) structure were estimated using Rayleigh-Gans scattering theory. This simple method suits for an approximate estimation of the influence of geometrical parameters of the PDLC structures on electrooptical characteristics. The conclusion has been made, that 'threshold' voltage of the electrooptical response is caused by geometrical parameters of the PDLC structures mainly, but not by the properties of the LC.
