Surface properties of amorphous carbon films

Abstract The sessile-drop experiment was conducted to analyze the wetting characteristics of the different amorphous carbon films before and after the plasma treatment. Initially in the carbon film–distilled water system the average contact angles have been measured within the values range from 50° to 70°. The plasma treatment of different allotropic carbon forms by low energetic ions increases very strongly the solid/liquid surface energy and reduces the contact angle down to 0°.
