INTERCALATION OF POLYANILINE IN MONTMORILLONITE AND ZEOLITE

The anilinium ion was encapsulated into the interlayer space of montmorillonite and the intrachannel space of NaY zeolite by the ion exchange method. After addition of ammonium peroxodisulfate, the loaded anilinium ions were polymerized to polyaniline (PAN). The structures of PAN in NaM and CsM are compared with that in NaY by means of UV-Vis, FTIR and EPR spectroscopies. The structures of PAN in NaY zeolite and montmorillonite hosts were shown to have the typical spectral features of emeraldine base and emeraldine salt respectively. Intercalation of polyaniline in montmorillonite was confirmed by the variation of the basal spacing, the resonances in EPR and the reduction of bulk conductivity.
