Abstract
The maximum alignment angle θeff and the effective rotational viscosity coefficient γ effi of polar liquid crystals, such as 4-n-octyloxy-4′-cyanobiphenyl (8OCB), are investigated in the vicinity of charged bounding surfaces. The quantities θeff and γ eff1 are calculated in the framework of the Ericksen-Leslie theory. The results of calculations demonstrate that, for a homeotropic alignment of molecules on charged indium tin oxide surfaces, the effective rotational viscosity coefficient γ effi can increase by 7.8% as compared to the bulk rotational viscosity coefficient γ1.
