Abstract

A new nanocomposite solid polymer electrolyte of Fe3O4 nanoparticles complexed with Polyethylene Oxide (PEO):Mg(ClO4)2 network have been prepared by means of solution-casting procedure. The Infra Red (IR) spectra of PEO:Mg(ClO4)2 show several changes in the intensity, shape and position of CH, COC and ClO4– bands when complexation occurs with nanosized Fe3O4. The COC vibrational mode observed at ~ 1100 cm–1 broadened in its width and shifted to a higher wavenumber in Fe3O4 complexed PEO:Mg(ClO4)2 composite electrolyte, when compared to Pure PEO, and PEO:Mg(ClO4)2 electrolytes. The higher degree of Mg(ClO4)2 salt dissociation was found by adding nanosized Fe3O4 to PEO:Mg(ClO4)2 solid polymer electrolyte. The ionic conductivity increases by the addition of Fe3O4 to PEO:Mg(ClO4)2 and optimized conductivity is found at 10 wt.% of nano Fe3O4, with a complement of one order larger when compared to PEO:Mg(ClO4)2 polymer electrolyte.
