Abstract

Concentration dependences of dielectric permittivity are studied in binary mixtures of liquid crystal with large value but different sign of dielectric anisotropy and in mixtures of highly polar 8OCB with non-mesogenous and non-polar stearic acid. Positive derivatives of the real part of ε from the additive values in a wide concentration range in observed both in different liquid crystalline and isotiprc phases. Results obtained are considered in comparison to previous works and described in terms of molecular packing and dipole interactions effects. Possible applications of such systems and their unconventional dielectric properties is discussed.
