摘要

The object of this research programme is to produce thermotropic liquid crystalline polymers, with robust mechanical properties, containing groups which complex with inorganic salts, and to measure the ionic conductivities of the salted polymers. To this end we require mesogenic (rigid rod) units sufficiently long to confer thermotropic behaviour, relatively flexible cation-complexing units in sufficient proportion to confer acceptible ionic conductivity, and physical properties such that the polymer can retain its shape and orientation at the proposed temperature of use. Main chain liquid crystalline polymers based on polyester triad mesogenic units together with polyethylene glycol spacers have been successfully synthesized and their properties investigated. The materials are mechanically robust and flexible and exhibit a liquid crystal phase above about 100 C. The polymers are capable of complexing with a suitable lithium salt and reasonable ionic conductivities have been measured.
