Abstract
Dynamic approach to mass transport study in cholesteric/nematic systems by the optical method provides the evaluation of the self-diffusion coefficients of both solute and solvent. These values are obtained by extrapolating to the C = 0 and C = 1 limits from the scaling law found between the diffusion coefficient and the concentration gradient. The numerical values of the local concentrations are obtained from the pitch values in both homogeneous and homeotropic boundary conditions.Keywords
