Synthesis and characterization of electroactive polymers and intercalated nanocomposites

The intercalation chemistry of molybdenum trioxide (MoO3), tin disulfide (SnS2) and graphite oxide (GO) has been investigated. Poly[oxymethylene(oxyethylene)] (POMOE) and poly[oligo(ethylene glycol) oxalate] (POEGO) have been completely inserted into the layered host of commercially available MoO3 by exploiting the swelling properties of its lithiated phase. On the other hand, partial intercalation of POMOE and POEGO into lithiated tin disulfide was obtained. The encapsulation of POMOE in the graphite oxide layered system was found to be complete. The new intercalated nanocomposites were characterized by XRD, TGA and elemental analysis.

A simple route for the synthesis of poly[bis-(methoxy ethoxy) phosphazene (MEEP) was developed and the product was characterized by NMR spectroscopy. Poly(dichlorophosphazene) (PDCP) has been synthesized by simple modification of the literature procedure. Synthesis of a new poly phosphazene substituted material was achieved by replacing chlorine atoms from the PDCP backbone with polyaniline. This new material was characterized by NMR spectroscopy.
