Abstract

The interest to liquid crystals confined in porous materials has greatly increased in recent years due to their important applications in new electro-optic technologies [1]. Confinements by pores and surface interactions produce strong effects on the properties of liquid crystalline systems both below and above the bulk clearing point [2,3]. The aim of this work is the study of a surface induced orientational anisotropy of constrained liquid crystals above the nematic-isotropic transition temperature on the basis of the stimulated echo experiments and the computer simulations.
