Determination of the Nematic Liquid-Crystal Substrate Interaction Potential by Means of Empirical-Method of Self-Consistent Director Field
A semi-empirical method is proposed for determination of the nematic liquid crystal-substrate interaction potential. Employing results of the dielectric constant epsilon and phase shift delta measurements, presented for 4-trans-4’-n-hexyl-cyclo-hexyl-isothiocyanatobenzene (6CHBT) and applying the self-consistent director field method, interaction potentials (6CHBT-polyimide) and (6CHBT-lecithin) have been estimated.
