Carbon nitride films, with good adhesion to surface, were deposited on aluminum surface plate by electrolysis of methanol-urea solution under high voltage condition for increasing the N content and sp(3) hybrid of C-N bonds. Carbon nitride electrodepostion was done in methanol and ethanol for various dielectric constants. The deposited films were characterized by X-ray Photoelectron Spectroscopy (XPS), Fourier Transform Infrared Spectroscopy (Fr-IR) and Scanning Electron Microscopy (SEM). The results indicated that the main components of films contained sp(3) hybrid of C and N with single carbon-nitrogen bonds in the film with some oxygen impurities. The atomic weight percent of C, N, and O elements contained found to be 57.6%, 36.5% and 5.8%, respectively. The coatings had a uniform, flat and smooth morphology with an approximate N/C atomic ratio of 0.63.
