Surface modification of indium tin oxide films by amino ion implantation for the attachment of multi-wall carbon nanotubes
Amino ion implantation was carried out at the energy of 80 keV with fluence of 5 x 10(15) ions cm(-2) for indium tin oxide film (ITO) coated glass, and the existence of amino group on the ITO surface was verified by X-ray photoelectron spectroscopy analysis and Fourier transform infrared spectra. Scanning electron microscopy images show that multi-wall carbon nanotubes (MWCNTs) directly attached to the amino ion implanted ITO (NH2/ITO) surface homogeneously and stably. The resulting MWCNTs-attached NH2/ITO (MWCNTs/NH2/ITO) substrate can be used as electrode material. Cyclic voltammetry results indicate that the MWCNTs/NH2/ITO electrode shows excellent electrochemical properties and obvious electrocatalytic activity towards uric acid, thus this material is expected to have potential in electrochemical analysis and biosensors.
