Abstract

Polyaniline (PAni) coated over montmorillonite clay (Mt) layers is reported through in-situ oxidative polymerization. A new approach of synthesis has been adopted in which oxidizing agent (FeCl₃·6H₂O) is first intercalated into organically modified montmorillonite clay (OMt) in THF solvent and this ferric ions intercalated clay layers are thereafter re-dispersed into aqueous solution of monomer for polymerization. Choice of THF and aqueous medium is governed by ease of intercalation of Fe⁺³ into OMt and subsequent diffusion of monomer into interlayer spaces during polymerization respectively. The intercalation of polymer within the interlayer spaces has been studied and confirmed using various techniques.
