Surface Modification of Indium Tin Oxide Film Electrodes

KeyWord:ITO electrode  surface modification  chemical adsorption  silanization  electrochemical grafting

Abstract:

      Indium tin oxide(ITO) thin-film electrodes have good physical(high conductivity and good light transmission) and chemical properties.Proper surface modification could further extend their applications in electroanalytical chemistry.Based on the present research status£¬the preparation and cleaning processes of ITO electrodes are briefly introduced in this paper£¬and the different modification methods are summarized£¬in which three of the most frequently employed methods£¬iª±e.chemical adsorption£¬silanization and electrochemical grafting are emphatically introduced.Finally£¬the challenges and future application prospects in the surface modification of ITO thin film electrode are briefly discussed.
