Paper Abstract

The orientation of various types of liquid crystals (LC) on thin films of azobenzene polymers exposed to ultra-violet (UV) light has been investigated. The LC orientation depends on a concentration of azobenzene side-chains linked to a main polymer chain and on a heat treatment. Effects of homeotropic and planar orientations were observed when polymer films were irradiated by unpolarized light. A change of LC orientation types took place when LC was filled at applied electric field.
