M. Inoue et al., Viscosity measurement of nematic liquid crystal using shear horizontal wave propagation in liquid crystal cell, JPN J A P 1, 40(5B), 2001, pp. 3528-3533
Propagation characteristics of a shear horizontal (SH) wave in a cell struc
ture containing a nematic liquid crystal layer are described on the basis o
f numerical analysis and experimental results. The SH wave propagation is d
escribed by the numerical analysis result for the nematic liquid crystal as
an anisotropic liquid. considering the director angle of the liquid crysta
l. The temperature dependence of effective viscosities of a typical nematic
liquid crystal N-(p-methoxybenzylidene)-p'butylaniline)] (MBBA) is evaluat
ed from the measurement of the phase velocity change of the SH wave in the
liquid crystal cell.
