Polypyrrole coatings have been electropolymerized onto carbon fiber bundles. Several process parameters were varied, and their effect on the morphology and composition of the coatings was studied. The parameters that were varied included the choice of supporting electrolyte, the concentration of electrolyte, the concentration of pyrrole monomer, the applied constant voltage, and time. SEM micrographs of the coated samples revealed at least four distinct morphologies. EDAX analysis, elemental analysis, and infrared spectroscopy all confirmed that part of the supporting electrolyte was present in the coatings. In addition, the parametric variation showed that the type and concentration of the supporting electrolyte had the greatest influence on the resulting morphologies of the coatings. Later, mechanical properties will be examined.
