Abstract
Homeotropic nematic layers of MBBA oriented by self-assembled monolayers of CTAB were studied by phase- sensitive flexoelectric spectroscopy method. H igher frequency part of the viscoelastic spectra provided information about surface dissipation of orientational energy. Temperature dependence of sur face viscosity was revealed for the first timer. Influence of area density of CTAB monolayer was also investigated.
