Abstract

O-aminobenzenesulfonic acid is incorporated between the sheets of Cu2Cr(OH)6Cl. H2O hydrotalcite-type materials. After heating, a narrow ESR signal characterisitic of conductive polymer behavior is observed for the hybrid phase. The reaction of polymerization fails in absence of the confinement supplied by the LDH host structure and of air atmosphere. The nanocomposite presents an electrochemical behavior in agreement with the presence of large polyanilinesulfonate (PAniS) units, whereas the electropolymerization gives rise first to the formation of dimers. Spin density is found to be greater with the electropolymerization after few cycles than after the heat treatment.
