Ionic transport in typical polymer electrolytes is highly coupled segmental motions of the polymer backbone. This has the effect of severely restricting ionic mobility either as the glass transition is approached or if the polymer crystallises. Hence, appreciable conductivities are observed only in amorphous phases at temperatures well above Tg. These temperatures could also be well above ambient. To avoid this circumstance, large amounts of plasticizer are often added. As a result many of the perceived advantages of a solid polymer electrolyte are lost.This led us to propose a new design strategy aimed at polymer electrolytes in which ionic transport is decoupled from viscous flow and can occur in this glassy phase. Although this approach is contrary to perceived wisdom, in our preliminary investigations of a family of side group liquid crystal polymer electrolytes (SGLCPEs) we have progressed some way to achieving this goal. Specifically, we observed appreciable ionic conductivities in materials having shear moduli indicative of solid behaviour. We now seek to exploit this discovery; this programme describes work aimed at both understanding ionic transport, while simultaneously creating a new generation of polymer electrolytes for further study.
