Abstract
Thin films of polyaniline, polypyrrole, polythiophene and poly(ethylenedioxythiophene) are electrochemically grown on indium-tin oxide-coated glass plates. The samples are then exposed to dodecanethiol or 1H, 1H, 2H, 2H-perfluorooctanethiol. These nucleophiles react with the surface to give near-monolayers of the thiols. Contact angle analysis and AFM studies reveal that significant changes result from these treatments, altering the surface energies of the materials. A method for quantifying the alteration in the surface properties and for examining the homogeneity of the coverage is detailed. This involves the modification of the AFM tip by attaching a 20 mu M sphere and making force-distance measurements of the surface under a layer of distilled water.
