The fluctuation layered structure of induced cholesterics

This work is dedicated to nematic liquid crystals structure studies and its correlation with an induced cholesterics supermolecular spiral organiztion fixing. The cholesteric-nematic mixtures on the base of polar and non-pola r nematics with the dopants of cholesterine esters are studied. The layered structure period temperature dependencies, correlation length and small-an gle X-ray scattering intensify in nematic-cholesteric mixtures show, that t he nematic matrix structural perfection is slightly disturbed when the chol esterine eaters molecules are introduced into the matrix.
