Abstract in another language

A thermoreversible (physical) gel of a nematic liquid crystal in its planar configuration is investigated. The transition temperatures of the gel are thermally and rheologically determined. The temperature for the nematic-isotropic transition is higher than that for the gel-sol transition, allowing the network to grow in the oriented nematic phase. The electrical Fréedericksz transition of the gel is investigated by using both an optical and an electrical detection method. The transition can be adjusted within a large voltage range by selecting the temperature of the sample. This behavior is determined by the thermal properties of the thermoreversible gel network.
