Résumé: Main attention of the contribution is devoted to polyaniline-poly(vinyl alcohol) cryogels and to the dependence of their dielectric characteristics on temperature and history (ageing, desorption), especially to non-Arrhenius behaviour around freezing point. Results obtained using standard contact methods (mainly broadband frequency analyser Novocontrol Alpha in frequency range 10-2–10+7 Hz) were compared with data obtained by developed contactless resonance method based on evaluation of eddy currents in samples exposed to changing magnetic field.
Mots-clés : conducting cryogels, polyaniline, dielectric properties, contactless method
