The anisotropy of electrical conductivity has been studied in polypyrrole deposited on poly(ethylene oxide)-copper(II) chloride complex films deposited by the dip-coating technique. The preconditioning of these films has a strong influence on the anisotropy of conductivity and in many cases the conductivity is found to be higher in the perpendicular direction than parallel to the direction of pull. There is also a critical speed of the substrate used during dip coating at which the anisotropy is found to be a maximum. These various results have been explained on the basis of the morphology of the polypyrrole deposit which is influenced by the poly(ethylene oxide) complex and confirmed by deliberate modification of the same complex by blending it with other polymers. © 1995.
