    NPB and arachidic acid (AA) are introduced to the ITO surface through Langmuir-Blodgett (LB) technique to modify the hydrophilic surface to hydrophobic surface. The π-A isotherms and AFM images of NPB-arachidic acid with different mol concentration show that they can form stable and condensed LB films, and the compactness are increased with the increasing of the NPB molecular concentration. The surface morphologies of the composite films were investigated by atomic force microscopy (AFM). The surface properties of the film are characterized by contact angle and cyclic voltammetry.
