Abstract
The fabrication of nanocomposites of poly(styrene sulphonic acid)(PSS), synthesised by sulphonation of polystyrene obtained by emulsion polymerisation of the monomer and characterised by FTIR and degree of sulphonation, with various proportions of graphite nanosheets (NanoG) by casting dispersions of NanoG in PSS aqueous solution is described. The products were characterised by morphology (XRD, SEM and TEM) and electrical conductivity, and the effects of filler content on electrical properties are discussed in comparison with the predictions of the classical percolation theory. 34 refs.
