The Anisotropic Electrical Conductivity of MBBA Containing Alkyl Ammonium Halides
The anisotropic electrical conductivity of MBBA containing alkyl ammonium halide dopants in the 10-6to 10-3 mole/liter concentration range was investigated. The conductivity data suggest the presence of associated cations and solvated anions. The anisotropic conductivity ratio, defined as (σ‖ -σ┴)/(1/3σ‖ +2/3σ┴), increases with decreasing radius of the halide ion and is shown to be an important physical parameter determining the figure of merit of the liquid crystal composition used in alphanumeric display devices.
