Abstract
Current noise and conductivity in composites of conductive spherical p olyaniline particles covered with non-conductive poly(vinyl alcohol) l ayers dispersed in the same polymer medium were investigated. As the p olyaniline particles are fully separated by insulating material, condu ctive percolation is not possible and electrical conductivity occurs o nly by thermally assisted charge hopping or possibly tunnelling. An in terpretation in terms of quiet conductive paths through the polyanilin e particles and noisy conductance through the poly(vinyl alcohol) matr ix is given.
