The influence of pressure‐induced structural changes on the ionic conductivity of zwitterionic polymers

In this investigation, ionic conductivity measurements are performed on N-oxide polymers neutralized with NaOH. The polymer samples were conformed in disk shapes using an Instron machine considering various values of the pressure required to compact the samples. The dielectric properties of these systems were obtained by the a.c. spectroscopy technique. Results indicate a substantial variation in the ionic conductivity due to the pressure-induced structural changes on the morphology of these samples, as confirmed by WAXS studies. © 1994 John Wiley & Sons, Inc.
