Abstract
AbstractIn this article, morphological structures are presented that are formed during spin coating of thin composite polymer films, containing a conjugated polymer. The system under study is a mixture of electrically conductive polyaniline doped with dodecylbenzenesulfonic acid and a conventional, nonconducting polymer—polystyrene or poly(methyl methacrylate). The dopant strongly influences film morphology, acting as a surfactant at a polymer/polymer interface. The effect of solution composition, spin‐coating atmosphere, and solvent on final morphology is analyzed. Experimental data were collected by means of several techniques: dynamic Secondary Ion Mass Spectrometry, Atomic Force Microscopy, UV–Vis spectroscopy, and optical microscopy. © 2012 Wiley Periodicals, Inc.
