摘要:

The influence of molecular properties on the rotational viscosity, γ1, of nematic liquid crystals is studied. The shear viscosity under flow alignment, ηs, is determined for the same liquid crystals. A significant correlation between both quantities is found. An equation is presented which allows the calculation of γ1from ηswith an error of about 20 per cent for the liquid crystals studied.
