Preparation and application of nanostructured conjugated polymer film by electrophoretic deposition

In this paper, the preparation of nanostructured films of a conjugated polymer, poly (3-octadecylthiophene), through electrophoretic deposition from colloidal suspension is described. The morphology of the film observed by an atomic-force microscope, indicated that the film consists of nanoparticles. It is suggested that the deposition, as well as drying of the film in the non-solvent atmosphere is a key to obtain nanostructured film. A light-emitting device fabricated from the nanostructured conjugated polymer film has emitted light, directly indicating that pin-hole free nanostructured film can be obtained.
