【Abstract】 Based on the pyrolysis technology of ionic liquid precursor, the carbon film is prepared on Al2 O3 substrate. The surface morphology, structure and tribological properties of carbon-based films containing the interlayer of sucrose are compared with those of carbon-based films with no transitional layer. The feasibility of using sucrose to prepare the transition layer is explored. The effect of sucrose inter layer on the properties of the carbon films prepared by the precursor of ionic liquids is studied. The structure and surface morphology of carbon films are analyzed by x-ray photoelectron spectroscopy(XPS). Scanning electron microscope(SEM), and the adhesion of different films is tested by scratch apparatus. The tribological properties of films are investigated. The results shows that the binding force between the membranes can be improved effectively by the sucrose interlayer.更多还原
