Abstract
Influence of fullerenes C-60 on the threshold voltage, dielectric and conductivity properties of smectic A liquid crystal 4-hexyloxyphenyl ether 4 '-hexyloxy 3 '-nitrobenzoic acid is investigated. It is shown that the transverse component of the real part of dielectric permittivity increases at the additive of fullerenes while the longitudinal component decreases. In this case, a maximum of dielectric absorption shifts to the high-frequency region. Conductivity increases at low frequencies and decreases at the high ones. Experimental results are explained by location of fullerenes between liquid crystal molecules reducing their interaction. As a result, the order parameter and viscosity of the matrix decrease.
