Abstract

A temperature-driven anchoring transition strongly influenced by ionic impurities appears in a nematic liquid crystal composed of centrosymmetric molecules. Two anchoring parameters, the tilt angle and the anchoring strength, were measured. The observed phenomena are explained as a result of a balance between the orienting tendencies of electric double layers and direct molecular interactions at the interface.
