Application of percolation concept to electrical conductivity of polyaniline/inorganic salt

Original language description

The dependence of the resistivity of protonated polyaniline/inorganic salt composites on the volume fraction of electrically conducting component was analyzed on the basis of the percolation theory. A short analysis and a discussion of basic treatments to the evaluation of percolation parameters are included. The microscopical observations showed a non-uniform distribution of polyaniline particles in the composites. The composites of polyaniline sulfate with ammonium sulfate and potassium bromide have alow percolation threshold (< 3 vol.% conducting component). This was explained as a property of segregated structure of the composites, which is formed because of a large difference in the particle sizes. Basic quantitative characteristics of the morphological structure were obtained using the percolation model, which was proposed by Ewen and Robertson to explain the properties of thick film resistors.
