摘要：

We describe the fabrication and characterization of new nanoband electrodes, based on ultrathin carbon films produced by carbonization of deposited polyacrylonitrile. Because of their controlled thickness (down to molecular dimensions) and high electrical conductivity, such electrodes show great promise for electroanalytical work. Sigmoidal voltammograms, characteristic of nonlinear diffusion, are obtained. Direct measurements in electrolyte-free organic media are illustrated. Effects of band thickness, scan rate, solute and electrolyte concentrations, and other variables are explored. These films and other forms of carbon from polyacrylonitrile present opportunities for a wide range of electrode materials.
