Observation of Adsorption and Desorption Processes of Impurity Ions in Nematic Liquid-Crystal Cells
A method for studying adsorption and desorption processes of impurity ions in nematic liquid crystal cells is proposed. The experimental results for 4-cyano-4’-pentyl biphenyl are interpreted in terms of a rate-equation approach and the time constants for the adsorption and desorption processes of the ions are determined.
