Abstract: Multilayer polymer thin films with well-defined molecular architectures have been fabricated by an electrostatic self-assembly process involving sequential exposure of glass substrates to polyelectrolyte solutions of sulfonated polyaniline and hexadimethrine bromide. Ultraviolet-Visible (UV-Vis) Spectroscopy indicates layer-by-layer growth of alternating monolayers of oppositely charged polymer chains whose structural integrity is verified by X-ray Photoelectron Spectroscopy (XPS). The surface roughness is measured to be 3 nm by Atomic Force Microscopy (AFM). The potential applications of these films in optoelectronic devices are discussed.
