V2O5 xerogel Nanocomposites

The direct intercalation of polyanihne doped with 12-phosphormohbdic acid (PANI-PMA) into V2O5 xerogels was reported by Posudievsky et al. Treatment of an aqueous solution of the xerogel or its lithium bronze with a solution of PANI-PMA in m-cresol, in equal amounts, led to the formation of (PANI-PMAo.o7)o.34V205. The conductivity of the nanocomposite was found to be 5.0 x 10 S cm [32].
