Influence of polarizing electric fields on the electrical and optical properties of polymer-clay composite system. (English) Zbl 1187.82133
Summary: We examined the electrical and optical properties of a new material containing polymer-clay nano-composite dispersed in a nematic liquid. The clay (Cloisite-type) was modified by copolymerization of maleic anhydride and divinyl benzene, using azobisisobutytironitrile as the initiator. The final polymer-clay nano-composite has an intercalated structure according to XRD patterns. We measured the thermally stimulated depolarization currents and determined the activation energies. Simultaneously we measured the optical transmission and we studied the influence of the previously applied polarizing electric fields.
