The influence of cyclodextrin on the electrochemical deposition of polyaniline from neutral perchloric solutions was determined. The oxidation of aniline and the polymer growth were investigated by cyclic voltammetry and electrochemical quartz crystal micro-balance in the presence of either beta-cyclodextrin or sulfated beta-cyclodextrin. The obtained results show the significant impact of the cyclodextrins on polyaniline growth rate, morphology and electrochemical properties of the resulting layers. The different effect was obtained in the presence of beta-cyclodextrin compared to sulfated beta-cyclodextrin. The incorporation of beta-cyclodextrin in the polyaniline layer results in comb like formations within the layer while the incorporation of sulfated beta-cyclodextrin in the polyaniline layer leads to more irregular morphologies and to the layers with the increased ohmic resistance.
